New Genetic Test Determines Risk of Autism

Boston (DbTechNo) – A new study to be published in the April print issue of Pediatrics details a new genetic test that can determine a child’s risk of being born with autism.

The test is called the chromosomal microarray analysis and has only been available for the last few years.

When compared to other forms of genetic tests which have been on the market for a longer period of time, the new CMA test was more accurate at predicting autism than the others.

The tests are performed to determine if the parents of autistic children are carrying abnormal genes or not, and can determine if parents are at greater risk of having multiple children with the condition.

“The CMA test alone has triple the detection rate of karyotyping or fragile X,” said co-senior author Bai-Lin Wu, director of the Genetics Diagnostic Laboratory at Children’s Hospital Boston. “CMA should be added to first-tier genetic testing for autism spectrum disorders.”
