Genetic test predicts risk for Autism

A team of Australian researchers, led by The University of Melbourne has developed a genetic test that is able to predict the risk of developing Autism Spectrum Disorder, ASD.

Lead researcher Stan Skafidas, Director of the Centre for Neural Engineering and Professor of Electrical and Electronic Engineering at the University of Melbourne, said the test could be used to assess the risk for developing the disorder.

This test could assist in the early detection of the condition in babies and children and help in the early management of those who become diagnosed, he said.

It would be particularly relevant for families who have a history of Autism or related conditions such as Aspergers Syndrome, he said.

Autism affects around one in 150 births and is characterised by abnormal social interaction, impaired communication and repetitive behaviours.

The test correctly predicted ASD with more than 70 per cent accuracy in people of central European descent. Ongoing validation tests are continuing including the development of accurate testing for other ethnic groups.

Clinical neuropsychologist, Dr Renee Testa from the University of Melbourne and Monash University, said the test would allow clinicians to provide early interventions that may reduce behavioural and cognitive difficulties that children and adults with ASD experience.

Early identification of risk means we can provide interventions to improve overall functioning for those affected, including families, she said.

A genetic cause has been long sought with many genes implicated in the condition, but no single gene has been adequate for determining risk.
