Scientists at the Washington University School of Medicine have uncovered more evidence of a genetic basis for autism. Reviewing surveys collected from more than 1,000 families with autistic kids, they discovered that siblings of autistic children who have not been diagnosed with the disease often exhibit mild traits of autism, including speech delays.
The team sifted through information about almost 3,000 children from 1,235 families in which at least one child was diagnosed with an autism spectrum disorder and in which there was at least one full biological sibling. The families were participants in the Interactive Autism Network, an online research registry that collects autism-related data from volunteer families nationwide.
