Study: Siblings of autistic children more likely to have autism than previously thought

A new study released this morning by the journal Pediatrics finds that the siblings of autistic children are more likely to have autism than previously thought.

Previous studies estimated that the ASD recurrence risk in younger siblings was between 3% and 10%. But this study found that the overall risk was much higher, at 18.7% and even higher in families with more than one affected sibling – about 32.2%.

Today on American Morning, Alycia Halladay, director for environmental research for Autism Speaks, joins Alina Cho to explain the study and to weigh in on how this research may impact future genetic screening and family planning decisions.
