How "Dark Matter" Regions of the Genome Affect Inflammatory Diseases – Technology Networks
Posted: May 14, 2020 at 5:45 pm
A study led by researchers at the Babraham Institute in collaboration with the Wellcome Sanger Institute has uncovered how variations in a non-protein coding dark matter region of the genome could make patients susceptible to complex autoimmune and allergic diseases such as inflammatory bowel disease. The study in mice and human cells reveals a key genetic switch that helps immune responses remain in check. Published in Nature, the research, involving collaborations with research institutions in the UK and worldwide, identified a new potential therapeutic target for the treatment of inflammatory diseases.Over the last twenty years, the genetic basis of susceptibility to complex autoimmune and allergic diseases, such as Crohns disease, ulcerative colitis, type 1 diabetes and asthma, has been narrowed down to a particular region of chromosome 11. This work has involved large scale genome-wide association studies (GWAS), a genome-wide spot-the-difference comparison between the genomes of individuals with or without a disease, to highlight regions of variation in the DNA code. This can identify potential genetic causes, and reveal possible drug targets.
However, most of the genetic variations responsible for the susceptibility to complex immune and allergic diseases are concentrated within regions of the genome that dont encode proteins the genomes dark matter. This means theres not always a clear gene target for further investigation and the development of treatments.
Recent advances in sequencing-based approaches have shown that these disease-associated genetic changes are concentrated within regions of DNA called enhancers, which act as switches to precisely regulate the expression of genes. Further technological developments have allowed scientists to map physical interactions between different remote parts of the genome in 3D, so they can connect enhancers in non-coding regions with their target gene.
To gain insight into inflammatory disease, a large team of researchers used these methods to study an enigmatic non-protein-coding region of the genome whose genetic variations are associated with increased immune disease risk. They identified an enhancer element that is required for the immune systems peace-keepers and immune response mediators, regulatory T cells (Tregs), to balance an immune response.
Lead researcher and Babraham Institute group leader, Dr Rahul Roychoudhuri said: The immune system needs a way of preventing reactions to harmless self- and foreign substances and Treg cells play a vital role in this. Theyre also crucial in maintaining balance in the immune system, so that our immune responses are kept in check during infections. Tregs only represent a small percentage of the cells making up our complete immune system but theyre essential; without them we die from excessive inflammation. Despite this important role, there has been little evidence that unequivocally links the genetic variations that cause certain individuals to be susceptible to inflammatory diseases to changes in Treg function. It turns out that non-protein-coding regions provided us with the opportunity to address this important question in the field.
Evolution gave the researchers a helping hand. The researchers took advantage of an approach called shared synteny, where not just genes are conserved between species, but a whole section of the genome. Similar to finding part of your book collection duplicated in your neighbors house, including the order of their arrangement on the bookshelf.
They used this genomic similarity to translate what was known about the enhancer in the human genome and find the corresponding region in mice. They then explored the biological effect of removing the enhancer using mouse models.
The researchers found that the enhancer element controls the expression of a gene in Treg cells, which encodes a protein called GARP (Glycoprotein A Repetitions Predominant). They showed that deleting this enhancer element caused loss of the GARP protein in Treg cells, and an uncontrolled response to a triggered inflammation of the colon lining. This demonstrated that the enhancer is required for Treg-mediated suppression of colitis, with a role for the GARP protein in this immune system control.
There was a similar effect in human Treg cells from healthy blood donors. The researchers identified an enhancer region whose activity was impacted by genetic variation specifically in Treg cells. The enhancer directly interacted with the human form of the same gene, and the genomic variations occurring in the enhancer element were associated with reduced GARP expression.
Dr Gosia Trynka, a senior author on the paper from the Wellcome Sanger Institute and Open Targets, said: Genetic variation provides important clues into disease processes that can be targeted by drugs. In our joint efforts here, we combined human and mouse research to gain invaluable insight into complex processes underlying immune diseases. This has identified GARP as a promising new drug target and brings us a step closer to developing more efficient therapies for people suffering from diseases such as asthma or inflammatory bowel disease.
Dr Roychoudhuri concludes: Decades of research have now identified the variations in our genomes that make some of us more susceptible to inflammatory diseases than others. It has been very difficult, however, to make sense of how these variations relate to immune disease since many of them occur in non-protein-coding regions, and therefore the implications of these changes are poorly understood. Studies such as these will enable us to link the genetic switches that commonly reside in such disease-associated non-coding regions with the genes they control in different cell types. This will yield new insights into the cell types and genes underlying disease biology and provide new targets for therapeutic development.ReferenceNasrallahet al. (2020).

U.K. genome sequencing project aims to identify genetic links to severe COVID-19 infection – BioWorld Online
Posted: at 5:45 pm
LONDON The U.K. is launching a 28 million (US$34.5 million) project to sequence the whole genome of every COVID-19 patient in the country treated in intensive care, with the aim of uncovering host genetic factors that lead some people to be more severely affected by the infection.
The study will involve up to 20,000 people currently or previously treated in one of 170 intensive care units (ICUs), whose genomes will be compared to 15,000 people with a confirmed infection who had mild or moderate symptoms.
It was evident from the first cases in China that people with co-morbidities experience more severe illness, but patients with the same underlying conditions have been found to respond very differently. While co-morbidities and factors such as age and obesity are important, it is thought this high variability in the severity of COVID-19 infections is linked to underlying genetic factors that influence response to the virus.
Backed by detailed medical records, the study will explore the spectrum of symptoms and attempt to pinpoint their genetic roots. The findings will provide biomarkers for assessing in advance which patients will react badly, help inform treatment with existing drugs and provide de novo targets.
This large-scale whole genome sequencing project is not beginning from a standing start, but builds on Genomicc (Genetics Of Mortality In Critical Care), launched in 2016, to sequence the genomes of patients with any condition who were so ill they required critical care.
To date, DNA samples have been collected from patients who were critically ill with influenza, SARS-CoV-1, MERS, sepsis and other causes.
With over 2,000 patients recruited, it is by far the largest study of critical care genetics in the world, said Kenneth Baillie, academic consultant in critical care at Edinburgh University and principal investigator. In total, we have 2,133 cases in Genomicc, but no results yet for COVID-19, he told BioWorld.
To date, Genomicc has been funded by a sepsis charity; the U.K. government funding and the urgency behind all COVID-19 research will accelerate the study.
Genomicc also will have the backing of Genomics England, the not-for-profit government funded company which has been working on translating advances in genomics into clinical practice.
So far, that work has focused on delivering genetic diagnoses for rare disease patients and selecting gene-targeted therapies in cancer, but Mark Caulfield, chief scientific officer, said Genomics Englands expertise can be applied to understanding why the virus is life-threatening for some, while others have a mild infection. By reading the whole genome, we may be able to identify variation that affects response to COVID-19 and discover new therapies, he said.
Genomics England is now recruiting volunteers who have been ill with COVID-19 to take part in the study. All of 35,000 COVID-19 genomes will be sequenced by Illumina Inc., which will share some of the costs via an in-kind contribution.
Focus on susceptibility
Baillies research into the genomes of critically ill patient builds on the observation that the cause of death following a serious infection is often not attributable to the direct impact of the pathogen or any toxin it produces, but a consequence of a systemic immune response.
Exploring the genetic underpinnings of that is one source of drug targets. A second source will be in identifying host factors the virus depends on for replication. In research published in January, Baillie and colleagues reported the results of a wide-scale screen in which they identified 121 host genes that are required for influenza A replication.
In a hugely heterogeneous disease, the large-scale sequencing of whole genome sequences is the best way to track down the factors underlying the spectrum of response to COVID-19 infection, Baillie said. I think this is one of the best ways to tackle this question. By focusing on extreme susceptibility, that is, patients with critical illness caused by COVID-19, we can increase the size of effect that we see for any genetic signals, making them easier to find, he said.
One very striking characteristic of people who suffer the worst effects of COVID-19 is that far more of them are men than women. Baillie said, It may well be that [Genomicc] gives us clues to explain the difference in susceptibility between the sexes.
Part of the overall study will focus on children and young adults with no known underlying health problems who have been severely affected by COVID-19. There have been reports that a very small number of children in the U.K., U.S. and Italy developed a significant multisystem inflammatory response associated with COVID-19.
The power of the COVID-19 whole genome sequence data will be amplified by linking it to virus genome data. Worldwide, the repository of viral sequences from patients now numbers tens of thousands. In the U.K., the COVID-19 Genomics UK (COG-UK) consortium has sequenced more than 10,000 virus genomes, meaning it will be possible to put together matched pairs of viral/patient genomes.
Linking [viral sequence] data to the patients own genome data in the Genomicc study may provide unique insights into how patient and virus genomes act together to influence the patients response to the infection, said Sharon Peacock, director of COG-UK.
The program is significant for many reasons not only to provide insights into the cause of the potential role of human genome in the severity of COVID-19, but also to provide a real opportunity to link other similar datasets globally, Naveed Aziz, chief administrative and scientific officer at CGEN, Canadas national genome sequencing and analysis platform, told BioWorld.
For example, the Canadian HostSeq program aims to sequence genomes of 10,000 COVID-19 positive people. The ability to query a larger dataset from across the globe will allow researchers to increase the power of COVID-19-related studies when it comes to investigating human gene variations associated with the immune response against infection by SARS-CoV-2, Aziz said.

Endophthalmitis detection by whole genome sequencing and qPCR – Ophthalmology Times
Posted: at 5:45 pm
Abstract / Synopsis:
Quantitative polymerase chain reaction and whole genome sequencing contribute to pathogen identification in endophthalmitis.
Worse outcomes after development of endophthalmitis postoperatively are associated with the presence of bacteria and higher bacterial loads of pathogens other than Staphylococcus epidermidis as detected by whole-genome sequencing (WGS) and quantitative polymerase chain reaction (qPCR).
The incidence rate of endophthalmitis that develops after intravitreal injections is low, but more and more injections are being administered annually in the US and the rate of endophthalmitis is climbing.
However, the current gold standard, cultures, seems less than adequate, in that the Endophthalmitis Vitrectomy Study (Arch Ophthalmol. 1995;113:1479-96) found that only 69.3% of cases were culture-positive, leaving the rest with no etiologic diagnosis.
Related: Diagnostic advances offer glimpse of endophthalmitis pathogens
In addition, the culture-positive rates may be even lower in endophthalmitis that develops following intravitreal injections, in that among 23 cases of endophthalmitis analyzed following 27,736 injections, 16 cases were found to be culture-negative (Ophthalmology. 2011;118:2028-34).
According to Cecilia Lee, MD, MS, and colleagues, as the prognosis of endophthalmitis appears at least partially dependent on the causative organism, the high rate of culture-negative cases suggests a need for a more sensitive modality for pathogen detection.
In light of this, Dr. Lee and colleagues conducted a prospective cohort study in which MidAtlantic Retina, the Retina Service of Wills Eye Hospital, Philadelphia, and the University of Washington, Seattle, participated.
Consecutive patients were enrolled who had a clinical diagnosis of endophthalmitis after any intraocular procedure or surgery within 6 weeks of presentation. The day that they were recruited into the study, all patients underwent either intraocular fluid biopsy or pars plana vitrectomy. qPCR for specific pathogens and WGS were performed, the investigators recounted.
Related: Small changes can help beat endophthalmitis bug
Study findingsFifty patients (52% men; mean age, 72 years) were enrolled in the study. Following qPCR and WGS, 24 cases were culture-positive and the remainder culture-negative. WGS identified the cultured organism in 76% of the culture-positive cases and identified potential pathogens in 33% of the culture-negative cases, said Dr. Lee, who is from the Department of Ophthalmology, University of Washington, Seattle. They published their findings on behalf of the Endophthalmitis Study Group in the American Journal of Ophthalmology. (2020; doi: https://doi.org/10.1016/j.ajo.2020.03.008.)
The most frequently cultured organisms were S. epidermidis followed by other Staphylococcus and Streptococcus species.
Regarding bacterial load, the median load was 3.32 (mean, 53.50; range, 0.028-480) in the culture-positive cases. In the WGS-positive but culture-negative cases, the median bacterial load was 1.44 (mean, 2.04; range, 0.35-6.19).
The visual outcomes in cases with S. epidermidis endophthalmitis did not differ from the visual outcomes in cases that were pathogen-negative; however, the patients who tested positive for organisms other than S. epidermidis had worse visual outcomes.
Related: Study targets therapies for endophthalmitis
The investigators found that in cases that had higher baseline bacterial DNA loads of pathogens other than S. epidermidis that were detected by WGS had worse visual acuity levels at months 1 and 3. Interestingly, the bacterial loads of S. epidermidis did not seem to affect the outcomes, the investigators reported.
qPCR identified Torque teno virus in 49% of cases and Merkel cell polyomavirus in 19% of cases. When Torque teno virus was present, there was a higher rate of secondary pars plana vitrectomy and retinal detachment.
The authors concluded that the culture/molecular pathogen testing status (for bacteria and virus) as well as the baseline visual acuity has prognostic significance for clinical outcomes including the visual acuity and secondary vitrectomy in endophthalmitis.
Molecular studies provide more extensive and sensitive characterization of pathogens and have the potential to allow for improved treat paradigms, they wrote. Further development of rapid, point-of-service molecular diagnostics and subsequent prospective randomized controlled clinical trials will allow for testing of new paradigms for risk stratification and individualized treatment for endophthalmitis.

Mainframes to PCs. $1B genome to $1k. The brain and mind are next. – TechCrunch
Posted: at 5:45 pm
Subject: Mainframes to PCs. $1B genome to $1k. The brain and mind are next.
Hello Humanity,
What a fun week it has been! After four years quietly building, we pulled back the curtains at Kernel, revealing how our brain recording hardware will replace room-sized machines.
Weve seen this before. Mainframes became PCs. The $1B genome became $1k. The brain and mind are next.
We also showed a fun demonstration: Kernel Sound ID, which decodes a persons brain activity and within seconds identifies the speech or song they are hearing. Here is the science.
So, where do we go from here? Unlike our steps, calories, likes and followers, the technology hasnt yet existed to meaningfully quantify our brains and minds in natural environments and at scale. The inner workings of the most complicated and consequential organ on the planet remains a black boxbut not for long. Consider this:
We live in a data-illuminated world, but the user manual for our brains has no biomarkers. The current gold standard, Diagnostic and Statistical Manual of Mental Disorders (DSM), has not a single number. Leaving us with no option but to describe cognition in hunches, not numbers.
Imagine a cardiologist explaining how your heart is doing with hunches. No electrocardiogram (ECG). No blood work. Just asking you some questions about how your heart feels. We dont self-introspect to determine our cholesterol levels either.
When it comes to understanding our own and others brains and minds, we are in medieval times, stuck with self-introspection.
Of the little we can measure of our brain today, we build around it. For example, traffic signals are designed around a few measures, including the 1) limits of human reaction 2) physics of braking distance required and 3) needs of society, managing traffic flow. Blood-alcohol levels are another example we measure this because we care about what it means for a drivers impaired cognition.
However, we cannot yet quantify and characterize decision making, cooperation, emotion, attention, bias, or focus because we dont have the numbers. Instead, we make guesses and rely upon hunches and hopes.
What if we could do better? What would such a world look like?
If we could quantify and characterize thoughts and emotions, conscious and subconscious, a Neuro-Quantified Era (NQE) would emerge. The foundation already exists to use numbers judiciously.
Perhaps in an NQE there would be bumper lanes for decision making, enabling us to bowl more cognitive strikes and fewer gutter balls. In new(ish) cars, when you want to change lanes but someone is in your blind spot, you get a warning that you are about to err.
Could we do the same for certain anxieties, risks, or maladaptive thoughts? (There is already a stress relieving GPS app that directs people through rush hour traffic. Again, this is based on a crude cognitive proxy a hunch.)
In a NQE, how would humans cooperate during a pandemic? Or, how would we manage an existential crisis such as climate change.something that happens gradually and then all of a sudden, doesnt have dopamine feedback loops, and cant be perceived with the five senses? A trio that is especially lethal to humans.
Future generations may condemn us for our mindlessness in using our god-like technology powers to encourage lesser versions of ourselves (ie. digital addiction, extremism, misinformation.) Our cognitive biases have held us back for too long.
Maybe a neurome, like our genome, would give us a blueprint of insight and plan for action. Could we create the needed bridge between our technology, science and institutions to systematically and methodically scaffold human progress?
Coronavirus has reminded us that human nature is fundamentally unchanged from millennia ago. We may find ourselves wanting to revisit first principles of what it means to be human to improve whats not working.
Sometimes the worst events in life become the greatest learning moments.

Pangolins May Not Have Been The Intermediary Host of SARS-CoV-2 After All – ScienceAlert
Posted: at 5:44 pm
Understanding the origins of the virus causing COVID-19 is one of the key questions scientists are trying to resolve while working out how to manage the pandemic. But in a fast-evolving situation, we're bound to point our fingers at a few innocent suspects along the way.
The current hypothesis goes something like this: SARS-CoV-2 passed through a mystery animal host in its suspected evolutionary journey from bats to humans. Critically endangered pangolins have been a favoured candidate for this intermediary host, but now a genomic analysis led by geneticist Ping Liu from Guangdong Academy of Science in China has provided evidence this may not be the case.
SARS-CoV-2 belongs to the Betacoronavirus genus of coronaviruses; this group of coronaviruses primarily infects mammals, and the new study suggests that pangolins are indeed natural hosts for them.
The team pieced together almost an entire genome of the coronaviruses found in two sick Malayan pangolins (Manis javanica). They called the coronavirus isolated from these critically endangered animals pangolin-CoV-2020. Its final sequence had 29,521 base pairs, only slightly shorter than the 30,000-odd base pairs making up SARS-CoV-2.
The resulting genome displayed a 90.32 percent sequence similarity to SARS-CoV-2 and 90.24 percent to the Rhinolophus affinis bat coronavirus BatCoV-RaTG13, which still remains the closest known relative to SARS-CoV-2, with a match of 96.18 percent.
But the sequence similarities don't reflect the full story. The genetic instructions for the all-important protein spike of the SARS-CoV-2 virus matched more between the bat and human coronavirus than the pangolin one.
However, the pangolin virus essentially shares the same ACE2 binding receptor as that used by the COVID-19 virus - the part of the spike that allows the virus to enter and infect human cells. This was also found in another study that is still undergoing review, and led to suggestions that the human coronavirus may be a type of hybrid (a chimera) between a bat and a pangolin virus.
Liu's team also thinks these similarities may indicate that a recombination event occurred somewhere in the evolution of these different viruses - where the viral genomes exchanged pieces of their genetic materials with each other. However, their analysis of the evolutionary relationship between the three viruses did not support the idea that the human version evolved directly from the pangolin one.
"At the genomic level, SARS-CoV-2 was also genetically closer to Bat-CoV-RaTG13 than pangolin-CoV-2020," they wrote in their paper.
There are clearly still a lot of unknowns. With well over 4 million confirmed cases around the world, and a death toll still increasing sharply, the need to understand as much as we can about this virus just continues to intensify.
However, one thing all these genetics studies have firmly ruled out is the idea that the virus was lab made.
As for the pangolins, they had been rescued by the Guangdong Wildlife Rescue Center after being smuggled for black market trade, and sadly succumbed to their illness. Liu's team could not determine if their deaths were linked to the coronavirus they found.
But perhaps a little good can arise from all this, at least for the world's most trafficked mammal, with the researchers concluding:
"Minimising the exposures of humans to wildlife will be important to reduce the spillover risks of coronaviruses from wild animals to humans."
The new research was published in PLOS Pathogens.

WHITEHALL ANALYTICA THE AI SUPERSTATE: Part 2 Is COVID-19 Fast-Tracking a Eugenics-Inspired Genomics Programme in the NHS? – Byline Times
Posted: at 5:44 pm
Nafeez Ahmed explores the troubling implications and assumptions of the Governments AI-driven gene programme.
In Part 1 of this investigation, I looked at how the convergence of an AI Superstate and corporate interests with health data lies at the heart of a new frontier for profit and surveillance. But the Governments response during the COVID-19 pandemic has revealed something even more profoundly disturbing: a fascination with genomics which moves from a merely descriptive tool to something so prescriptive it verges on eugenics.
The NHSX app is simply one project with a questionable design which appears to result from the Governments much wider project to remake the NHS.
At the core of the new NHSX AI drive is the goal of predictive, preventive, personalised and participatory medicine, according to an NHSX document published in October 2019. Pivotal to this AI-driven transformation is genetics:
Key to unlocking the benefits of precision medicine with AI is the use of genomic data generated by genome sequencing. Machine learning is already being used to automate genome quality control. AI has improved the ability to process genomes rapidly and to high standards and can also now help improve genome interpretation.
The NHS Genomic Medicine Service is starting with a focus on cancer, rare and inherited diseases,but its broader goal is far more comprehensive. Initially, the hope is that genomics will expand to cover other areas, such as pharmacogenomics, which looks at how an individuals genes influence a particular biological process that mediates the effects of a medicine, according to The Pharmaceutical Journal.
But the end-goal is to convert the NHS into a health service oriented fundamentally around the role of genetics in disease. The aspiration is that from 2020, and by 2025, genomic medicine will be an embedded part of routine care to enable better prediction and prevention of disease and fewer adverse drug reactions. The GMS aims to complete five million genomic analyses and five million early disease cohorts over the next five years.
By 2025, genomic technologies will be embedded through multiple clinical pathways and included as a fundamental part of clinical training. As a result, it is hoped that there will be a new taxonomy of medicine based on the underlying drivers of disease.
But, this entire premise is deeply questionable. There is little evidence that the underlying drivers of disease are primarily genetic.
Last December, a study in the journal PLOS One found that genetics usually explains no more than 5-10% of the risk for several common diseases. The study examined data from nearly 600 earlier studies identifying associations between common variations in the DNA sequence and more than 200 medical conditions. But its conclusion was stark: more than 95% of diseases or disease risks including Alzheimers, autism, asthma, juvenile diabetes, psoriasis, and so on could not be predicted accurately from the DNA sequence. A separate meta-analysis of two decades of DNA science corroborated this finding.
The implication is startling: that the entire premise for the billions of pounds this Government is investing in building a new privatised NHS infrastructure for AI-driven genomic medicine is scientifically unfounded.
The obsession with genetics can be traced directly back to the Prime Ministers chief advisor, Dominic Cummings.
Cummings set out his vision for the NHS in a February 2019 blog, which although previously reported on has not been fully appreciated for its astonishingly direct implications. While focusing on disease risk, the blog flagged-up Cummings hopes that a new NHS genomics prediction programme would ultimately allow the UK to, not just prevent diseases, but to do so before birth in effect a nod toward the selective breeding techniques at the core of eugenics.
They are using the COVID-19 crisis to erect a corporate superstate powered by mass surveillance and AI. Their grim ambition is to reach into the very DNA of every British citizen.
His vision for what a genomics-focused NHS would look like bears startling resemblance to the core ideas of eugenics the discredited pseudoscience aiming to improve the genetic quality of a human population by selecting for superior groups and excluding those with inferior genes. Its worst manifestations were exemplified by the Nazis.
In the blog, Cummings wrote:
Britain could contribute huge value to the world by leveraging existing assets, including scientific talent and how the NHS is structured, to push the frontiers of a rapidly evolving scientific field genomic prediction. He called for free universal SNP [single-nucleotide polymorphis] genetic sequencing as part of a shift to genuinely preventive medicine, to be rolled-out across the UK. This approach holds the promise of revolutionising healthcare in ways that give Britain some natural advantages over Europe and America.
Later in the post, Cummings allowed himself to speak more directly to what natural advantages could actually entail. He claimed that a combination of AI-driven machine learning with very large genetic sampling could enable the precise prediction of complex traits such as general intelligence and most diseases.
The two scientists Cummings cited as the primary sources for his vision were educational psychologist Robert Plomin and physicist Steven Hsu.
Plomin, described by Cummings as the worlds leading expert on the subject, is a renowned scientist. But he also has a history of association with the eugenics movement, according to Dr David King, founder of Human Genetics Alert and previously a molecular biologist. (Sir David King, the former chief scientific adviser to the UK Government, has also criticised the genome sequencing goldrush).*
When The Bell Curve a book advocating the genetic inferiority of African Americans was published, Plomin was a key signatory to a statement defending the science behind the book, explained Dr David King in a paper for the non-profit watchdog Human Genetics Alert. The statement carefully avoided explicitly endorsing The Bell Curves racist conclusions (aptly summarised by Francis Wheen as black people are more stupid than white people: always have been, always will be. This is why they have less economic and social success), while failing to repudiate them. Plomins fellow co-signatories included several self-proclaimed scientific racists, Philippe Rushton and Richard Lynn. Plomin has also published papers with the American Eugenics Society and spoken at several meetings of the British Eugenics Society (the latter rebranded itself as the Galton Institute in 1989) both of which advocated racial science.
In December 2013, Plomin was called as an expert witness to the House of Commons Education Select Committee, where he called for the Government to focus on the heritability of educational attainment. Twenty-five minutes into the session, Dominic Raab who as Foreign Secretary and First Secretary has stood in for Boris Johnson during his period of absence due to COVID-19 prompted Plomin to focus more specifically on explaining his views about genetics, intelligence and socio-economic status.
Just two months before Plomins parliamentary testimony, a 237-page dossier by Cummings then a top advisor to Education Secretary Michael Gove was leaked to the press. The paper claimed that genetics plays a bigger role in a childs IQ than teaching and called for giving specialist education as per Eton to the top 2% in IQ. Pete Shanks of the Centre for Genetics and Society described Cummings policy proposal as a blatantly eugenic association of genes with intelligence, intelligence with worth, and worth with the right to rule.
The Cummings dossier which cites Plomin extensively further reveals that, according to Cummings, he had invited Plomin into the DfE [Department for Education] to explain the science of IQ and genetics to officials and ministers.
The Education Select Committees report shows that, at the time of Plomins testimony, the Government was resistant to these views. But, the position appears to have changed since then, with figures such as Cummings, Raab and Gove now at the seat of power under Prime Minister Boris Johnson.
Plomin would go on to work with Steven Hsu, who was involved in a major Chinese genome sequencing project based on thousands of samples from very high-IQ people around the world. The goal was to identify genes that can predict intelligence. Hsu went on to launch his own company, Genomic Prediction. In slide presentations about his work from 2012, Hsu approvingly quoted British eugenicist Ronald Fisher, closing his slides with the following quotation: but such a race will inevitably arise in whatever country first sees the inheritance of mental characters elucidated. Hsus slides, wrote David King, include plans for a eugenic breeding scheme using embryo selection to improve the overall IQ of the population.
Yet, on his blog, Cummings confirmed that Hsu has recently attended a conference in the UK where he presented some of these ideas to UK policy-makers. Among the ideas Hsu presented to Cummings colleagues in Government was that the UK could become the world leader in genomic research by combining population-level genotyping with NHS health records. Hsu further claimed that risk prediction for common diseases was already available to guide early interventions that save lives and money.
Hopefully the NHS and Department for Health will play the Gretzky game, take expert advice from the likes of Plomin and Hsu and take this opportunity to make the UK a world leader in one of the most important frontiers in science, enthused Cummings.
Plomins claim that intelligence is determined primarily by genes contradicts a vast body of scientific literature, and is largely overblown. One of the latest studies debunking Cummings hopes was led by the University of Bristol and published in March. Based on a sample size of 3,500 children, the study found that polygenic scores (which combine information from all genetic material across the entire genome) have limited use for accurately predicting individual educational performance or for personalised education.
The study did not dismiss a role for genes outright, noting genetic scores modestly predictededucational achievement. The problem was that these predictions were less accurate than using standard information known to predicteducational outcomes, such as achievement at younger ages, parents educational attainment or family socio-economic position.
Last November, Hsus Genomic Prediction began touting new report cards to its customers. The cards displayed alleged results of genetic tests containing warnings that embryos might have low intelligence, grow up to be short, or have other conditions such as diabetes. But, according to the MIT Technology Review, the company has struggled both to validate its predictions and to interest fertility centres in them. In the month prior to Hsus grand announcement, the first major study to test the empirical viability of screening embryos, led by statistical geneticist Shai Carmi of the Hebrew University of Jerusalem, concluded that the technology is not plausible.
The lack of scientific substantiation has not stopped Cummings from suggesting a more interventionist vision for the NHS, which could be accused of paving the way for a new form of eugenics. In his February 2019 blog, he wrote: We can imagine everybody in the UK being given valuable information about their health for free,truly preventive medicinewhere we target resources at those most at risk, and early (evenin utero) identification of risks. This passage appears to nod to the core eugenics notion of selective breeding using embryo selection. Cummings even went further to endorse the goal of editing genes to fix problems.
In a further telling but slightly more well-known passage, Cummings characterised the genomics programme as a precursor to more realistic views about IQ and social mobility: It ought to go without saying that turning this idea into a political/government success requires focus on A) the NHS, health, science, NOT getting sidetracked into B) arguments about things like IQ and social mobility. Over time, the educated classes will continue to be dragged to more realistic views on (B) but this will be a complex process entangled with many hysterical episodes. (A) requires ruthless focus.
This passage affirms that Cummings approach is deliberately deceptive. The focus on health and the NHS is revealed as a cover for a longer-term vision to usher in more realistic views about things like IQ and social mobility. The passage also lifts the rock on Cummings weakest point that he fears that public attention on these more realistic views could sidetrack the broader strategy before it reaches fruition.
In the words of Dr David King, Cummings deference to Hsu, who openly advocated eugenics breeding programmes, suggests that the Prime Ministers chief advisor clearly favours this strategy for Britain; of course, this is precisely what all the European countries were trying to achieve in the heyday of eugenics to overcome their imperialist competitors by improving the national stock.
This, it seems, is the essence of Cummings ambition to use the NHS genomics prediction programme as a mechanism to provide Britain natural advantages over Europe and America.
And in this context, it is impossible to ignore the implications of Cummings appointment of Andrew Sabisky to a senior role advising Boris Johnson. When Johnsons spokespeople were asked repeatedly whether the Prime Minister would condemn Sabiskys sympathies for racist eugenics, he repeatedly refused. Sabisky later stepped away from the role.
The COVID-19 pandemic has now provided the Government with the opportunity to double down on its goals of extending genome sequencing across the UK population.
While genomic sequencing of the Coronavirus is undoubtedly an important scientific task to map and understand it, the crisis fits neatly into Cummings call for a ruthless focus on the NHS as a vehicle for Britains genetic enhancement.
On 23 March, when the UK finally instituted a lockdown at least three weeks after being informed that hundreds of thousands of people (and potentially up to a million) people were at risk of death from its previous policy of herd immunity, the Government launched a new scientific research consortium coordinated by Cambridge University along with the Wellcome Sanger Institute, the NHS and Public Health England.
The consortium would gather samples from patients confirmed with COVID-19 and send them to genetic sequencing centres across the country to analyse the whole genetic code of the samples. The project was billed breathlessly as an essential step in being able to control the pandemic and prevent further spread.
Unsurprisingly, it has done no such thing. Instead, six weeks later, the UK has ended up with the highest COVID-19 fatality rate in Europe.
As the death toll approaches the same level of British civilian casualties during the Second World War, the Governments strategy has privileged ambiguous, extortionate high technology solutions, pouring hundreds of millions of pounds into powerful private sector players with no transparency or due process. Meanwhile, traditional, proven, public health strategies such as better border controls, or extensive contact tracing and testing by scaling up local capacity, were inexplicably delayed for months.
On 13 March, the Government launched a new partnership between the NHS, Genomics England, the GenOMICC consortium, and US biotech giant Illumina, to conduct a nationwide human whole genome sequencing study targeting COVID-19 patients in 170 intensive care units.
The Governments new genome sequencing partner, Illumina, has previously produced genetic sequencing systems marketed to police agencies in China to facilitate its genetic profiling of the minority Uyghur population in Xinjang the largest system of discriminatory, ethnically-targeted biometric surveillance using DNA ever created.
It is difficult to avoid the conclusion that Dominic Cummings and his fellow ideologues in Government are hell-bent on pursuing a pseudo-scientific vision that has been years in the making.They are using the COVID-19 crisis to erect a corporate superstate powered by mass surveillance and AI. Their grim ambition is to reach into the very DNA of every British citizen.
Dominic Cummings was contacted for this article, but is yet to reply.

Genetic origins of hybrid dysfunction | Stanford News – Stanford University News
Posted: at 5:44 pm
In a small pool nestled between two waterfalls in Hidalgo, Mexico, lives a population of hybrid fish the result of many generations of interbreeding between highland and sheepshead swordtails. The lab of Molly Schumer, assistant professor of biology at Stanford University, has been collecting these fish for years to study the evolution of hybrids.

Were just realizing that hybridization affects species all across the tree of life, including our own species many of us carry genes from Neanderthals and Denisovans, said Schumer, referring to two ancient human species that interbred with our ancestors. Understanding hybridization and the negative and positive effects that can come from genes that have moved between species is important in understanding our own genomes and those of other species with which we interact.
In a new paper, published May 14 in Science, the researchers pinpoint two genes responsible for a melanoma that often develops near the tails of male highland-sheepshead hybrids. The finding marks only the second time that a hybrid dysfunction has been traced to specific genes in vertebrates. (The only other case where scientists have narrowed hybrid dysfunction in vertebrates down to the single-gene level is in a longstanding hybrid population of mice in Europe and their relatives.)
People have long known that the offspring of two different species tend to have genetic flaws. For example, mules which are donkeys-horse hybrids are infertile. Ironically, in order to find the genes responsible for such dysfunctions, researchers need hybrids that are fit enough to breed for several generations after the initial hybridization. Otherwise, the pieces of their genomes that come from the parental species are so large that it is nearly impossible to trace the influence of any one gene.

This is what makes the highland-sheepshead hybrids an exceptional case study. They have been interbreeding for about 45 generations, resulting in genomes that contain smaller chunks of parental DNA, which are easier to inspect at a single-gene level.
Weve known about genetic incompatibility between the genes of two species since the 1940s. Despite that, we dont know many of the genes that cause these negative interactions, said Daniel Powell, a postdoctoral fellow in the Schumer lab and lead author of the paper. Our lab has clearly defined natural hybrids and weve developed the genomic resources for both parental species. These fish represent a unique system for addressing this question.
In order to home in on the genes responsible for melanoma in hybrids, the researchers first turned their attention to the pure sheepshead swordtails and the genetic origin of a black spot some of these fish develop which is non-cancerous but found in the same location as the hybrids melanoma. Analyzing the genomes of nearly 400 individual fish, they linked the black spot with the presence of a gene called xmrk. Following that lead, the researchers concluded that xmrk was also more highly expressed in hybrids with melanoma compared to those without it altogether, it could explain 75 percent of all variation in the spotting they studied in both the pure sheepshead and hybrid fishes.
The researchers also found that another gene called cd97 which some hybrids inherit from their highland swordtail ancestors was more highly expressed in the highland swordtails and in hybrids than in sheepshead swordtails. Further genetic evidence suggests that cd97 and xmrk interact in some way to produce melanoma in the hybrids.
Interestingly, even though neither gene is associated with melanoma in the parental swordtails species, theyre both linked to cancer in other animals. In a distantly related swordtail hybrid, for example, xmrk interacts with another gene not cd97 to cause melanoma, and a gene related to cd97 has been associated with cancer in humans.
Taken together, these findings yield a puzzling picture. Weve ended up with competing but not mutually exclusive ideas about hybrid incompatibility and disease, said Powell. Weve lent credibility to the idea that some genes might be vulnerable to breaking down in different species which is surprising, given the randomness of evolution. But we also have evidence for the idea that there is a diversity of genetic causes for similar dysfunctions.
Schumer says she took a bit of a gamble when she focused her studies on hybridization, but her bet is paying off.
When I started my PhD in 2011, it was really not accepted that hybridization was common in animals. The best-known examples were mules and fruit flies. Its been such a massive shift and a fun time to be working on this question, said Schumer, who is senior author of the paper and a member of Stanford Bio-X. What weve arrived at now is the best kind of project in science: one that raises way more questions than answers and spins you off in a bunch of different directions.
Through future work, the researchers want to figure out why hybrid swordtails with melanoma are less likely to survive in the wild and in captivity. They are also curious to know why so many of these fish have the melanoma its possible that, when it comes to mate selection, females prefer males with the large black spots generated by melanoma. Already, they have lined up several ideas to further understand whether genes go wrong in a repeatable way in hybrids, or if what theyve found in xmrk and cd97 is closer to coincidence.

Pangolins’ Genome Suggest That Pharmaceutical Suppression Of The Immune Response Could Improve Covid-19 Outcomes – IFLScience
Posted: at 5:44 pm
Recent reports have been describing how some of the worst outcomes from Covid-19 in humans is caused by an inflammatory immune response. Research published in the journal Frontiers in Immunologyhas revealed that pangolins, whichcancarry coronaviruses, may be protected from the disease as they lack two virus-sensing genes thatare known to elicit the kind of extreme immune response seen in humans.
Pangolins are scaly animals thatresemble anteaters and are the most trafficked animal in the world. Its been suggested they could potentially be the intermediary animal thatenabled Covid-19 from bats to humans, though there is noconclusive evidence for this theory. As such, the team from the Medical University of Vienna in Austria decided to study their genome to see if here lay an explanation as to how these animals can tolerate having a virus in their systemsthatis so devastating to other animals.
They analyzed the genome sequence of pangolins and compared it to other mammals, including humans, cats, dogs, and cattle. Their findings revealed that the two key genes thatsignal an immune response in other mammals are missing from pangolins, which could potentially provide some explanation as to why this disease is tolerated by these animals.
"Our work shows that pangolins have survived through millions of years of evolution without a type of antiviral defense that is used by all other mammals," says co-author Dr Leopold Eckhart in a statement. "Further studies of pangolins will uncover how they manage to survive viral infections, and this might help to devise new treatment strategies for people with viral infections."
The discovery is significant as it could suggest that gene suppression is a potential route for treatment. As the pandemic has developed, physicians across the globe have been reporting that the inflammatory immune responsetriggered by these key genes in some patients causes whats known as a cytokine storm. Cytokines are proteins in the body thatactivate immune cells. In Covid-19, these have been found to flock to the lungs, causing hyperinflammation thatcan kill the patient rather than helping them.
As the response by the immune system is sometimes whats killing infected patients, its possible that pharmaceutical suppression of gene signaling could be a route of treatment for severe cases of Covid-19. However, Eckhart cautions that reducing the bodys immune response could also make the symptoms of the disease worse.
"The main challenge is to reduce the response to the pathogen while maintaining sufficient control of the virus, he suggested. He notedthat this could be achieved by reducing the intensity or by changing the timing of the defense reaction."
The discovery still doesnt explain exactly how pangolins can tolerate coronavirus, as Eckhart suggests that another gene called RIG-I, which is also a virus sensor, could potentially play a role. However, the findings provide theintriguingpossibility of suppressing immune responses in the body as a means of securing better outcomes for Covid-19 patients.

Craig Venter: 20 years of decoding the human genome – DW (English)
Posted: April 13, 2020 at 11:48 am
The decoding of the genome was a sensation, although the announcement by Craig Venter on April 6, 2000, was somewhat premature. It actually took another year before the Human Genome Project (HGP), which was in competition with Venter, published its peer-reviewed research results in the scientific journal Science and Nature on February 15, 2001.
Battle for first place
The decoding of the genome was a race for scientific fame between the HGP, which is government-funded by the US, and Venter with his private company Celera Genomics. The government researchers lagged somewhat behind Celera Genomics in their work. By April 2000, they had been able to decode only 54% of the human genome.
The genome is made up of the genetic storage material deoxyribonucleic acid (DNA). It contains all hereditary information of life.

Craig Venter 1998 in the laboratory of his company Celera Genomics. Venter invented the shotgun sequencing method.
Going after the genetic material with a shotgun
Venter used a different sequencing method than the HGP researchers: namely, the so-called shotgun method that he developed. In this method, the individual DNA fragments are generated randomly. This is similar to shooting at the long chain with a shotgun and then looking at and reading out the fragments individually.
However, Venter also used HGP data to achieve his goal. And that was an ambitious one: The human genome consists of 3.2 billion base pairs the letters of life, so to speak. Finding them all was a mammoth task for him and the competing researchers. But the design of this genetic chain is actually quite simple.
It consists of a sequence of only four different building blocks: the DNA bases cytosine (C), guanine (G), adenine (A) and thymine (T). It is the sequence of these bases that determines our eye or hair color or whether we have any hereditary diseases.

Many doors leading nowhere
Only a few sections of the entire genome are the genes that contain important instructions for building blocks of life such as proteins. "According to current knowledge, however, a large proportion of DNA is an evolutionary remnant and has no function whatsoever. This makes it clear that although the door to the code of life has been opened, countless new doors are hidden behind it," writes chemist Friederike Fehr from the Max Planck Institute for Dynamics and Self-Organization in Gttingen.
Many genes that were discovered in the genome sequence had been unknown until then. "So the effects or tasks associated with them must also be researched. The sequence of letters alone is of limited help in this regard," Fehr writes.
Long road to medical applications
It was only with the completion of sequencing that the project of decoding the human genome could bear practical fruit. Although Venter published his own personal genome in the scientific journal PLoS Biology in 2007, this, too, was of rather symbolic importance. Gene sequencing in itself was only a first step toward a fundamental change in our medicine.
Scientists still had to research and assign the respective functions of the individual building blocks of the genome, i.e. find out which building block is responsible for what. They did this with the help of mice. Their genome is largely identical to that of humans and thus provided a basis for understanding the functions of human genes.
Experts believe that it could take dozens, if not hundreds, of years to really understand the human genome.
Read more:Who's the daddy: Does it really matter where your DNA comes from?
What do we get out of this?
The genomes of two people differ. These differences are the basis for the genetic predisposition to certain diseases.
Increasingly, genetic tests are being offered that enable experts to identify some of these predispositions and thus determine whether or not a person carries an increased risk of disease. A saliva sample is sufficient for this.
The most important thing in all these tests is to interpret the results correctly, for example, to determine if there is the disposition for Alzheimer's or diabetes.
With the help of genome research, it is now possible to identify various gene functions. This in turn helps doctors to treat certain diseases, including in children with an immune deficiency that is hereditary. Doctors can even implant new genes into these children to treat the disease.
Breast and ovarian cancer become apparent in the alterations of two genes (BRCA1 and BRCA2). A genetic risk for a tumor disease can be detected only in a few cases by genetic analysis.
There is still much to be done
The human genome consists of roughly22,500genes. Researchers around the world were astonished at this result as, believe it or not, a water flea has 30,907.
How complex a living being is, therefore, not dependent only on the number of genes. US President Bill Clinton said on April 6, 2000: "Now we are learning the language with which God created life." We now know that we still need a lot more vocabulary before we master that language.

In 1891, a Croatian born, Argentine criminologist, Juan Vucetich, started building up the first modern-style fingerprint archive. Since then, fingerprints have become one of the main forms of evidence used to convict criminals. Here, a police officer spreads dust on the lock of a burglarized apartment. Fingerprints become visible.
He uses an adhesive film to capture the fingerprint. Then he glues it to a piece of paper. In the past, comparing fingerprints was a painstaking affair. Officers had to compare fingerprints found at the scene of a crime, one-by-one, with those of possible suspects. These days computers do the job.
Taking fingerprints used to be a messy affair - with ink and dirty hands. These days scanners have replaced the inky mess. And the data can immediately be sent to a database and turned into biometrical data.
The computer identifies typical spots within the ridge patterns of the fingerprint. These include forks in the lines, spots and the location of the center of the print. Fingerprints are never the same between two people - not even with identical twins.
No chance! Here, officials use fingerprint scanners during an election in Nigeria. It's how they make sure the people voting are registered voters and that they only vote once.
This is an important question for officials who have to decide about the refugee or asylum status of applicants. In the European Union all migrants are supposed to have their fingerprints taken at the first point of entry - provided, of course, the local police officers are equipped with the scanners.
Many smartphones now come with fingerprint recognition software, such as the iPhone's Touch-ID. The owner of the phone unlocks it with his fingerprint. If someone else finds or steals the phone, they have no way of getting at any encrypted data within.
This is an Automatic Teller Machine (ATM) in the Scottish town of Dundee. Customers wanting to withdraw money need to show biometric proof of identity - in the form of a fingerprint. Not good news for pickpockets.
Since 2005, German passports, and many other passports, contain a digital fingerprint as part of the biometric information stored on a RFID (radio-frequency controlled ID) chip. Other information on the chip includes a biometric passport photo. The facial image is similar to fingerprints: no two images are alike.
Facial recognition software, which uses biometrics, is well advanced. It is possible to identify suspects within large crowds, with surveillance cameras. Also internet services and private computer owners are increasingly making use of facial recognition software to sort holiday pictures and tagging them to names.
Alec Jeffreys discovered DNA-fingerprinting almost accidentally in 1984 during research at the University of Leicester. He identified a specific pattern on DNA segments, which were different for every human. He created a picture, which looks like a barcode at the supermarket.
Germany's Federal Criminal Police Office (BKA) started storing such barcodes in a federal database in 1998. Investigators have since solved more than 18,000 crimes, using genetic fingerprints.
It's not just criminals who get identified. Many innocent people can be cleared of criminal charges through good identification. For some, technology has saved their lives. Kirk Bloodsworth spent almost nine years on death row. The US Innocence Project has proved the false incarceration of more than 100 people using DNA evidence.
The first big test for DNA-fingerprinting came with the mass murder of Srebrenica. Bodies, exhumed from mass graves, were systematically identified using DNA techniques. They were then reburied by their loved ones. Here, five year old Ema Hasanovic pays last respects to her uncle. More than 6,000 victims of the massacre - mostly men - were identified using DNA-fingerprinting.
You may be surprised, but there's biometric information in sounds and other digital data. Voice recognition software can, for instance, identify people making threatening phone calls - the human voice is also unique. And don't forget: we leave all kinds of digital traces on the internet, which hold clues to who we really are.
