UC-Davis Study Evaluates Autism Risk Among Siblings
The future sibling of a child born with autism has a 19%Â chance of developing the condition, according to a new study led by Sally Ozonoff, a professor of psychiatry and behavioral sciences at the UC-Davis MIND Institute. The study found that the risk of developing autism increases to 32% if a child has at least two older siblings with the condition. Previous, smaller studies estimated the autism recurrence risk at between 3% and 10%.
