Most genetic studies use only white participants and that affects public health – ThePrint

Text Size:A- A+

Few areas of science have seen such a dramatic development in the last decade as genomics. It is now possible to read the genomes of millions of people in so-called genome-wide association studies. These studies have identified thousands of small differences in our genome that are linked to diseases, such as cancer, heart disease and mental health.

Most of these genetic studies use data from white people over 78% of participants are of European descent. This doesnt mean that they represent Europe. In fact, only three nationalities make up most of the participants: the US, UK, and Iceland. Even though the UK and the US have very diverse populations, their non-white citizens have rarely been included in genetic research.

In recent years, efforts to collect multi-ethnic data have increased. One example is the UK Biobank, a collection of data from half a million British people accessible to any bona fide researcher. It includes some 35,000 DNA samples from people who are either non-European or mixed-race. Yet 92% of research papers on UK Biobank only used the data from the European-descent samples. So collecting data doesnt automatically solve the problem of non-white representation in research.

The under-representation of non-European groups is problematic for scientific and ethical reasons. The effects of gene variants that are present only in the unstudied groups remain unknown, which means important clues about the causes of diseases might be missed. Such undiscovered genes would not be included when testing for genetic diseases. So a person carrying one of them could wrongly get a negative genetic test result and might be told that they are not at increased risk of developing the disease.

Our recent work also shows that existing genetic findings might not apply equally to non-European populations. We found that some gene variants predicting high cholesterol in white populations do not lead to the same heart problems in people from rural Uganda. These findings should serve as a major warning to the field of genetics one cannot blindly apply findings from ancestrally European groups to everyone else.

It is important to support the global application of research because scientists have a moral responsibility to develop science for the benefit of the whole of humanity, not restricted by ethnic, cultural, economic or educational boundaries. Some 80% of the worlds population live in low and middle-income countries where healthcare and research are constrained by limited financial and human resources. We should not overlook this part of the world.

Studying different populations has advanced the medical field for everyones benefit. For example, the first disease gene mapped in humans was the gene for Huntingtons disease in 1983, identified through examining a large population of patients in villages surrounding Lake Maracaibo in Venezuela. The area was found to have the largest concentration of Huntingtons disease sufferers in the world, which helped them to find the gene.

More recently, a study of schizophrenia found new risk genes by using African and Latino American samples. Genetic risk scores based on results from these groups improved the ability to predict who would develop schizophrenia in all ethnic groups.

Two things need to happen if we want to avoid increasing health disparities and instead share the medical benefits of genomic science across countries and ethnic groups. First, we need more large diverse studies. First steps in this direction are being taken by the Human Hereditary and Health in Africa Initiative. PAGE and All of Us are paving the way to recruit more diverse ethnic groups in the US, and East London Genes and Health focuses on people of South Asian origin in London.

And second, to make sure diverse ethnic data resources are widely used by researchers, the challenges of analysing genetic data from ancestrally diverse samples need to be addressed. While there are statistical solutions, more work is needed to make them easy to use and give clear guidance about the best approach.

Understanding how genetic risk and social inequality interact to influence disparities in disease risk and outcomes will be critical to improving public health for all.

We need to understand the culture of whales so we can save them – The Conversation CA

Posted: at 10:20 pm

We often think of culture as solely human. We think of our music, our clothes, our food, our languages. However, culture stretches far beyond Homo sapiens. As evidence of the existence of culture in other animal groups emerges (from insects, rats, fish to land mammals, primates and dolphins), humans need to rethink what it means to have culture. We must accept that what we have long considered our own might be shared.

This is especially important because culture can have important implications for conservation. Understanding an animals culture might be the only way to save them.

As a PhD candidate studying culture in a non-human species, the sperm whale, I have had the chance to witness its implications. The more time I spend with whales and learning from them, the more I am convinced that acknowledging their culture is necessary to understand and protect them.

While most people have a general idea of what culture is, defining it can prove difficult. Culture is pervasive and, at the same time, it can express itself in such small, almost non-perceptible ways. Biology defines culture as shared information (or behaviour) that you acquire socially from your peers.

The importance of culture has long been recognized in humans. It is how we successfully inhabited all the biomes of our planet. Culture dictates our social interactions; the spontaneity of fashion and music; the laws that govern our societies and civilizations; the causes of our wars; the reason why, right now, you are reading this article instead of foraging in the forest.

Culture shapes every aspect of our lives and has allowed us to become the dominant species we are today. However, although humans might be the most cultural species, they are not the only cultural species.

Instead, culture expressed in small and big ways is found throughout the animal kingdom: chimpanzees in West Africa use tools to crack nuts, capuchin monkeys have group-specific social rituals, dolphins cooperate with fishermen to obtain food, songbirds and humpback whales have ever-changing songs, bighorn sheep follow cultural migratory routes, reef fishes have preferred mating sites, bumblebees learn from each other to solve complex puzzles.

And this is only the very tip of the iceberg. Every year, more evidence emerges on to the presence of culture in animals.

Beyond primates, the animal group for which we have the most evidence of culture are the cetaceans (whales and dolphins). Among them, the sperm whale has received particular attention.

Like us, sperm whales have families, they have strong affiliations with a few individuals and they are extremely social. Such a social environment is the perfect substrate for culture.

Sperm whales are matrilineal, which means that females stay with their mothers, forming groups called social units. These social units are comprised of one or two families and are stable over their entire lives. They travel together, socialize together, forage together and learn from each other. Beyond social units, sperm whale societies are also organized at a higher tier called vocal clans. Vocal clans include thousands of individuals and can be recognized acoustically.

Whales from different vocal clans sound incredibly different!

The most exciting part, however, is that individuals from different vocal clans not only have extremely different repertoires but also do not associate with each other, even if they live in the same environment. For example, in the Eastern Caribbean where I study sperm whales, we know about two vocal clans: EC1 and EC2. These two vocal clans have been identified in the same area (around the island of Dominica) but have never been seen interacting with each other: not even once in the 15 years the Dominica Sperm Whale Project has been studying the population.

In contrast, social units that belong to the same vocal clans are regularly observed foraging and socializing together.

Why is that? They live in the same environment, so surely, these differences are not the result of geographic adaptations. Could it be genetics? The evidence says otherwise: genetics cant explain the variation in vocal repertoire. The only remaining explanation is culture. Perhaps whales actively choose to avoid whales from different vocal clans. They learn a specific vocal repertoire from their mothers and then only associate with individuals that share that same repertoire.

EC1 vocal clan audio clip.

EC2 vocal clan audio clip.

These short audio clips are from the two vocal clans present in the Caribbean: EC1 and EC2. While EC1 whales often make clicks in the pattern click-click-click-click-click, EC2 whales often make clicks in the pattern click-click-click-click-click. These patterns have the same number of clicks, but different tempos.

Culture has important implications for conservation. If a population is subdivided into cultural groups, then conservation efforts targeting only one group will lead to a loss of diversity.

If cultural knowledge is mostly obtained from older matriarchs, then protecting these individuals at all costs should be our priority. If species are able to learn socially, they might respond differently to anthropogenic stressors. And yet, we seldom hear about it.

Acknowledging the presence of culture in other species would go against our anthropocentric view of the world: a world where humans are at the end of the evolutionary tree, smarter, more advanced and more important than other species.

It would blur the line between us and them. Once this occurs, how could we justify putting these cultural beings in cages, treating them as legal property and destroying their habitats? Perhaps it is time to re-think culture and acknowledge that other species might share what we long considered our own.

Gender-Specific Brain Cells Have Just Been Discovered Inside The Brains of Mice – ScienceAlert

Posted: at 10:19 pm

Male and female mouse brains could have significant differences that reach right down to the cellular level, according to a new discovery.

Based on a reading of their genetic activity, neurons in a part of the mouse nervous system responsible for aggression and mating behaviours appear to be chemically structured in subtle but distinctly different ways between the two sexes.

These findings haven't been tested in other mammal species as yet, so we can't read too much into them. But it's a fascinating study that warrants further investigation in the brains of other animals.

Researchers from the California Institute of Technology and the Allen Institute for Brain Science in Seattle looked at a region of the brain called the ventrolateral subdivision of the ventromedial hypothalamus (VMHvl) in both male and female mice.

The VMHvl is tiny, made up of a mere 4,000 cells in mice, but still has quite a schedule on its hands, playing an important role in metabolism and complex sexual and social behaviours.

To identify cell types in the region, the researchers usedsingle cell RNA reading technology, which identifies genes that have been actively translated into RNA.

This is important, because while a species' full genome is kept in the nucleus of each cell, only a limited number of these genes will actually be expressed into proteins that meet the needs of the specific cell type. For example, a blood cell has different needs and therefore will activate different genes than a skin cell.

This technology provided the scientists with a snapshot of the 'books' being read in each cell's genetic library, giving them a clear idea of how each cell's individual physical make-up and activity differs.

Cells are considered to be of a certain type if clusters of genes in close proximity are expressed together to carry out a task.

In total the team identified 17 distinct types of brain cells in this tiny bit of brain tissue, which they then verified using glowing genetic tags in a process called fluoro in-situ hybridisation.

While that might sound like a lot of brain cell types, uncovering such a level of diversity shouldn't be all that surprising. Similar research has already identified scores of cell types across the entire hypothalamus.

What hadn't been seen before in mammals, at least were clear differences in neuron types between the male and female brains they analysed.

Some of these cell types were found in vastly greater numbers among mice of one gender or the other. One in particular was already known to make an enzyme that was present only in male mouse brains.

But another newly identified cell type was specific to female mice, not being found at all in male mice.

Importantly, these differences weren't a direct result of contrasting sex chromosomes, with the distinct brain cell types traced back to patterns of genes on parts of the genome both sexes possess.

Having genes that are generally active in one sex but not the other is hardly shocking. The small but significant leap in this case is finding clusters of activity large enough in brain cells to make them physically different types.

One thing that did come as a surprise was that only a few of these specific variations seemed to match specific behaviours, posing questions on just what it is many of these gender-biased cell types do.

"The results show that there are differences between male and female mammalian brains at the level of cellular composition as well as gene expression but that those differences are subtle, and their functional significance remains to be explained," says California Institute of Technology biologist, David Anderson.

It's a conclusion that's sure to polarise opinions on what is already a controversial topic. Research on the culture and biology of human gender is a divisive topic marked by a history of stereotypes and misinformation

On top of that, it's difficult to know how studies on lab animals might apply to humans. We're unlikely to be unique, but it's an assumption that would require further research to support.

Treading cautiously, studies like this one can't be dismissed out of hand either.

Like mice, there's a good chance our own brains not only promote different behaviours depending on whether we have a Y chromosome, but have fundamentally different cell types that just might be responsible for sex-specific functions.

That doesn't mean men are from Mars and women are from Venus. Genetics is complicated, and while we can generalise based on patterns, it doesn't dismiss the significance of individual variations or cultural influences.

Technology that can provide a detailed library list of genes being actively read in individual cells is changing what we know about everything from mental health to evolution to our own developing bodies.

We're almost certain to be surprised by just how diverse human biology can be.

This research was published in Cell.

Stem cell therapy is for animals too – SciTech Europa

Posted: at 10:19 pm

Stem cell therapy for animals has seen breakthroughs

Stem cell therapy is increasingly becoming a more mainstream form of medicine. Usually applied to humans, the use of this regenerative treatment is now also being extended to animals including cats and dogs. Regenerative medicine, particularly stem cell treatment has seen many advancements in recent years with some groundbreaking studies coming to light.

Taking the cells from bone marrow, umbilical cords, blood or fat, stem cells can grow to become any kind of cell and the treatment has seen many successes in animals. The regenerative therapy has been useful particularly for treatment of spinal cord and bone injuries as well as problems with tendons, ligaments and joints.

Expanded Potential Stem Cells (EPSCs) have been obtained from pig embryos for the first time. The cells offer groundbreaking potential for studying embryonic development and producing transnational research in genomics and regenerative medicine, biotechnology and agriculture.

The cells have been efficiently derived from pig preimplantation embryos and a new culture medium developed in Hong Kong and Cambridge enabled researchers from the FLI to establish permanent embryonic stem cell lines. The cells have been discovered in a collaboration between research groups from the Institute of Farm Animal Genetics at the Friedrich-Loeffler-Institut (FLI) in Mariensee, Germany, the Wellcome Trust Sanger Institute in Cambridge, UK and the University of Hong Kong, Li Ka Shing Faculty of Medicine, School of Biomedical Sciences.

Embryonic stem cells (ESC) are derived from the inner cells of very early embryos, the so-called blastocysts. Embryonic stem cells are all-rounders and can develop into various cell types of the body in the culture dish. This characteristic is called pluripotency. Previous attempts to establish pluripotent embryonic stem cell lines from farm animals such as pigs or cattle have resulted in cell lines that have not really fulfilled all properties of pluripotency and were therefore called ES-like.

Dr Monika Nowak-Imialek of the FLI said: Our porcine EPSCs isolated from pig embryos are the first well-characterized cell lines worldwide. EPSCs great potential to develop into any type of cell provides important implications for developmental biology, regenerative medicine, organ transplantation, disease modelling and screening for drugs.

The stem cells can renew themselves meaning they can be kept in culture indefinitely, and also show the typical morphology and gene expression patterns of embryonic stem cells. Somatic cells have a limited lifespan, so these new stem cells are much better suited for long selection processes. It has been shown that these porcine stem cell lines can easily be modified with new genome editing techniques such as CRISPR/Cas, which is particularly interesting for the generation of porcine disease models.

The EPSCs have a high capacity to develop not only into numerous cell types of the organism, but also into extraembryonic tissue, the trophoblasts, making them very unique and lending them their name. This capacity could prove valuable for the future promising organoid technology, where organ-like small cell aggregations are grown in 3D aggregates that can be used for research into early embryo development, various disease models and testing of new drugs in petri dishes. In addition, the authors were able to show that trophoblast stem cells can be generated from their porcine stem cells, offering a unique possibility to investigate functions or diseases of the placenta in vitro.

A major hurdle to using neural stem cells derived from genetically different donors to replace damaged or destroyed tissues, such as in a spinal cord injury, has been the persistent rejection of the introduced material (cells), necessitating the use of complex drugs and techniques to suppress the hosts immune response.

Earlier this year, an international team led by scientists at University of California San Diego School of Medicine successfully grafted induced pluripotent stem cell (iPSC)-derived neural precursor cells back into the spinal cords of genetically identical adult pigs with no immunosuppression efforts. The grafted cells survived long-term, displayed differentiated functionality and caused no tumours.

The researchers also demonstrated that the same cells showed similar long-term survival in adult pigs with different genetic backgrounds after only short course use of immunosuppressive treatment once injected into injured spinal cord.

Senior author of the paper Martin Marsala, MD, professor in the Department of Anesthesiology at UC San Diego School of Medicine said: The promise of iPSCs is huge, but so too have been the challenges. In this study, weve demonstrated an alternate approach.

We took skin cells from an adult pig, an animal species with strong similarities to humans in spinal cord and central nervous system anatomy and function, reprogrammed them back to stem cells, then induced them to become neural precursor cells (NPCs), destined to become nerve cells. Because they are syngeneic genetically identical with the cell-graft recipient pig they are immunologically compatible. They grow and differentiate with no immunosuppression required.

Co-author Samuel Pfaff, PhD, professor and Howard Hughes Medical Institute Investigator at Salk Institute for Biological Studies, said: Using RNA sequencing and innovative bioinformatic methods to deconvolute the RNAs species-of-origin, the research team demonstrated that pig iPSC-derived neural precursors safely acquire the genetic characteristics of mature CNS tissue even after transplantation into rat brains.

NPCs were grafted into the spinal cords of syngeneic non-injured pigs with no immunosuppression finding that the cells survived and differentiated into neurons and supporting glial cells at all observed time points. The grafted neurons were detected functioning seven months after transplantation.

Then researchers grafted NPCs into genetically dissimilar pigs with chronic spinal cord injuries, followed by a transient four-week regimen of immunosuppression drugs again finding long-term cell survival and maturation.

Marsala continued: Our current experiments are focusing on generation and testing of clinical grade human iPSCs, which is the ultimate source of cells to be used in future clinical trials for treatment of spinal cord and central nervous system injuries in a syngeneic or allogeneic setting.

Because long-term post-grafting periods between one and two years are required to achieve a full grafted cells-induced treatment effect, the elimination of immunosuppressive treatment will substantially increase our chances in achieving more robust functional improvement in spinal trauma patients receiving iPSC-derived NPCs.

In our current clinical cell-replacement trials, immunosuppression is required to achieve the survival of allogeneic cell grafts. The elimination of immunosuppression requirement by using syngeneic cell grafts would represent a major step forward said co-author Joseph Ciacci, MD, a neurosurgeon at UC San Diego Health and professor of surgery at UC San Diego School of Medicine.

Other recent advancements include the advancement toward having a long-lasting repair caulk for blood vessels. A new method has been for generating endothelial cells, which make up the lining of blood vessels, from human induced pluripotent stem cells. When endothelial cells are surrounded by a supportive gel and implanted into mice with damaged blood vessels, they become part of the animals blood vessels, surviving for more than 10 months.

The research was carried out by stem cell researchers at Emory University School of Medicine and could form the basis of a treatment for peripheral artery disease, derived from a patients own cells.

Young-sup Yoon, MD, PhD, who led the team, said: We tried several different gels before finding the best one. This is the part that is my dream come true: the endothelial cells are really contributing to endogenous vessels.

When cells are implanted on their own, many of them die quickly, and the main therapeutic benefits are from growth factors they secrete. When these endothelial cells are delivered in a gel, they are protected. It takes several weeks for most of them to migrate to vessels and incorporate into them.

Other groups had done this type of thing before, but the main point is that all of the culture components we used would be compatible with clinical applications.

This research is particularly successful as previous attempts to achieve the same effect elsewhere had implanted cells lasting only a few days to weeks, using mostly adult stem cells, such as mesenchymal stem cells or endothelial progenitor cells. The scientists also designed a gel to mimic the supportive effects of the extracellular matrix. When encapsulated by the gel, cells could survive oxidative stress inflicted by hydrogen peroxide that killed unprotected cells. The gel is biodegradable, disappearing over the course of several weeks.

The scientists tested the effects of the encapsulated cells by injecting them into mice with hindlimb ischemia (restricted blood flow in the leg), a model of peripheral artery disease.

After 4 weeks, the density of blood vessels was highest in mice implanted with gel-encapsulated endothelial cells. The mice were nude, meaning genetically immunodeficient, facilitating acceptance of human cells.

The scientists found that implanted cells produce pro-angiogenic and vasculogenic growth factors. In addition, protection by the gel augmented and prolonged the cells ability to contribute directly to blood vessels. To visualise the implanted cells, they were labelled beforehand with a red dye, while functioning blood vessels were labelled by infusing a green dye into living animals. Implanted cells incorporated into vessels, with the highest degree of incorporation occurring at 10 months.

Additional details for the event can be found here.

About Galactosemia Galactosemia is a rare metabolic disease that affects how the body processes a simple sugar called galactose, and for which there is no known cure or approved treatment available. Galactose is found in foods, but the human body also naturally produces galactose on its own, so dietary restriction cant prevent complications of disease. It is estimated that the U.S. Galactosemia population is approximately 2,800 patients, based on newborn screening data identifying 2,500 infants through 2014, and the estimated birth rate of 80 patients per year. High levels of galactose circulating in the blood and tissues of Galactosemia patients enables Aldose Reductase to convert galactose to a toxic metabolite, called galactitol, which causes long-term complications ranging from CNS dysfunction to cataracts.

About AT-007AT-007 is a central nervous system (CNS) penetrant Aldose Reductase inhibitor (ARI) in Phase 1/2 development for treatment of Galactosemia. AT-007 has been studied in in an animal model of Galactosemia, which demonstrated that AT-007 reduces toxic galactitol levels and prevents disease complications.Applied Therapeuticsis conducting a biomarker based development program in patients with Galactosemia, based on the recently released draft industry guidance on drug development for low prevalence, slowly progressing rare metabolic diseases. The company received Orphan Designation for AT-007 for Galactosemia inMay 2019.

New Data from Ambry Genetics Demonstrates Impact of First Major Advancement in Over 10 Years to Increase Diagnostic Yield in Genetic Testing for…

Posted: at 5:08 pm

ALISO VIEJO, Calif., Oct. 15, 2019 /PRNewswire/ --Ambry Genetics(Ambry), a leading clinical genetic testing lab, will present data at the American Society of Human Genetics (ASHG) annual conference this week from the first prospective study of paired RNA and DNA genetic testing for hereditary cancer risk, called +RNAinsight. The data from this study of the first 1,000 patients to receive +RNAinsight show a significant increase in diagnostic yield (identifying mutations in our DNA as disease-causing) compared to DNA testing alone. This is the first major increase in diagnostic yield for hereditary cancer risk in over 10 years. Through +RNAinsight, Ambry is the first and only lab to offer paired RNA and DNA genetic testing for hereditary cancer as a commercially available clinical test.

Standard DNA testing excludes large portions of DNA, thereby missing some mutations that cause increased risks for cancer. In addition, DNA testing for hereditary cancer risk can produce inconclusive results and fail to determine that a variant (an error in our DNA) increases cancer risk. These limitations impact patients and their families because doctors may not have the information needed to recommend appropriate preventive, early detection steps, or certain therapeutic treatments, and relatives may not be referred for genetic testing and subsequently may not be referred for necessary high-risk surveillance. Adding RNA to DNA testing overcomes these limitations for a substantial number of patients as RNA provides considerably more evidence than DNA alone about whether our DNA has variants that increase cancer risk.

At ASHG, Ambry will present data showing that +RNAinsight both (1) identified new variants that increased cancer risk and that would have been missed with DNA testing alone, and (2) determined whether certain variants actually increased cancer risk even though DNA testing alone would have been inconclusive and left doctors without this crucial information.

"Combining RNA and DNA genetic testing lets more people know they have genetic mutations that increase their risks for cancer, empowering them to take action to better manage their cancer risks," said Tyler Landrith, Ph.D., an Ambry scientist who will present the study. "+RNAinsight is the first major, genetic-testing advancement in over 10 years to increase diagnostic yield for hereditary cancer risk."

Dr. Landrith will present data from a prospective analysis of 1,000 patients who received RNA genetic testing (for up to 18 genes). The data show a relative increase in diagnostic yield of 9.1 percent more than DNA testing alone. Adding RNA genetic testing also resulted in a 5.1 percent relative decrease in the number of patients that would have received inconclusive results with DNA testing alone and would not have learned whether they had increased cancer risk.

The prospective study also validated the accuracy of +RNAinsight, establishing a large control dataset of healthy patients. This dataset allowed Ambry researchers to establish a baseline for benign and disease-causing mutations across the genes tested. Dr. Landrith will address the validation in his presentation.

In addition to the prospective study, Ambry Senior Research Associate Blair Conner, M.S., will present data at ASHG showing that RNA genetic testing provided additional evidence to clarify the interpretation of 15 complex variants in genes associated with increased risks for breast, ovarian, colorectal, uterine, and other cancers. Without RNA genetic testing, these variants would have remained inconclusive. This means that past, current, and future patients who otherwise would not have learned they have increased risks for these cancers will now have crucial information to more precisely tailor their medical management for the prevention, early detection, and treatment of cancer.

"An inconclusive result can be unsettling for patients, especially for patients with a strong family history of cancer. Both clinicians and patients may worry that current technology has missed disease-causing mutations in the genes tested," said Ms. Conner. "These data show how +RNAinsight was able to overcome the technological limitations of DNA genetic testing by turning inconclusive results into actionable information for clinicians to better guide patient care."

+RNAinsight is now available through doctors and genetic counselors around the country. For more information on RNA genetic testing, please go to http://www.ambrygen.com/RNAinsight.

Top Researchers to Present Discoveries Made Possible by Bionano’s Saphyr System for Genome Imaging Technology at the ASHG 2019 Annual Meeting -…

Posted: at 5:08 pm

SAN DIEGO, Oct. 16, 2019 (GLOBE NEWSWIRE) -- Bionano Genomics, Inc. (Nasdaq: BNGO) today announced that disease researchers using Bionanos Saphyr system for whole genome imaging will present their results at the American Society of Human Genetics (ASHG) Annual Meeting, between October 15-19 in Austin, Texas.

The impact of analysis using the Saphyr system for ultra-sensitive and ultra-specific genome-wide detection of structural variation will be presented at ASHG with 22 oral and poster presentations and an Educational Event hosted by Bionano.

ASHG 2019 represents a milestone for Bionano, with a record number of presentations demonstrating novel discoveries through our genome mapping technology, said Erik Holmlin, Ph.D., CEO of Bionano. The growing use of the Saphyr system in disease research illustrates the value in identifying genomic variations for deep understanding of disease origin and diagnostic development.

Optical mapping through Saphyr enables the direct observation of large genomic variations through imaging of fluorescently labeled, megabase-size native DNA molecules. Next-generation sequencing (NGS), in contrast, relies on short-reads that piece together sequence fragments in an attempt to rebuild the actual structure of the genome. NGS often misses large DNA variations, such as deletions, insertions, duplications, and translocations and inversions. Genome mapping resolves these structural variations for more insight into the genetic variations that cause disease.

Below is a summary of key presentations to be given at ASHG 2019 featuring the use of optical genome mapping:

Genetic diagnosis of sex development disorders through optical mappingHalf of disorders of sex development (DSD) patients lack a firm diagnosis. Prof. Eric Vilain, from George Washington University and Childrens National Medical Center, will present research validating the diagnostic and gene discovery use of Bionano genome mapping to identify structural variants in patients with DSD. The talk, entitled Integration of optical genome mapping and sequencing technologies for identification of structural variants in DSD, will be presented on Wed. Oct. 16 at 5:15 - 5:30 pm in the convention center Level 3, Room 361D.

Genomic mapping has the potential to replace a combination of current cytogenetic techniquesCurrently, a comprehensive clinical analysis of genomic aberrations requires a combination of various assays such as CNV-microarrays, karyotyping and fluorescence in situ hybridization (FISH). Dr. Tuomo Mantere, from Radboud University Medical Center, will present data directly comparing traditional cytogenetic assays with Bionano mapping in leukemia patient samples to illustrate that genome mapping can identify all aberrations found by the three conventional technologies combined, and additional variants as well. The poster, entitled Next-generation cytogenetics: High-resolution optical mapping to replace FISH, karyotyping and CNV-microarrays will be presented on Thurs. Oct. 17, between 2 - 3pm, PgmNr 2533/T.

Genomic architecture reveals critical factors that may contribute to schizophrenia-associated 3q29 chromosomal deletionDeletions at the 3q29 chromosomal locus are associated with a 40-fold increase in risk for schizophrenia. Knowing the features that contribute to genomic instability is critical for identifying risk factors of chromosomal deletions. Trenel Mosley, from Emory University, will present the discovery of novel genomic structural characteristics found in 12 patients with 3q29 deletion and their parents using Saphyr. The poster entitled, Optical mapping of the schizophrenia-associated 3q29 deletion reveals new features of genomic architecture, will be presented on Wed. Oct. 16, between 2 - 3pm, PgmNr 1389/W.

Bionano and NGS resolve complex rearrangements in extrachromosomal, circular DNA in glioblastoma The rapid growth of aggressive tumors such as glioblastoma is partially caused by the rapid amplification of oncogenes in circular structures outside of native chromosomes. Because these structures do not occur in the reference genome, standard analysis methods fail to correctly assemble them. Jens Luebeck, from the University of California, San Diego, demonstrates that a combination of Bionano genome mapping and NGS resolves important breakpoints and gene amplifications in extrachromosomal DNA. The talk, entitled Integrated Analysis of NGS and Optical Mapping Resolves the Complex Structure of Highly Rearranged Focal Amplifications in Cancer, will be presented on Sat. Oct. 19, from 10:15 - 10:30am PgmNr: 323

Bionano Educational Event will feature research on muscular dystrophy, prenatal development & neurodegenerative disordersAt Bionanos educational event, Dr. Alka Chaubey from Perkin Elmer Genomics, Dr. Frances High from Mass General Hospital for Children, and Dr. Mark Ebbert from the Mayo Clinic will present findings from their work using the Saphyr system for structural genomic resolution. Analysis of chromosomal repeats, complex genomic haplotypes, and risk loci found in genetic disease will be highlighted by the speakers. Entitled Resolving Structural Variants Across the Whole Genome to Power Your Next Discovery in Human Genetics, the event will take place on Thurs. Oct 17, from 12:45 - 2:00pm at the Marriott Marquis, Houston, River Oaks, Level 3, and include a complimentary lunch.
