Scientist Link 60 Genes to Autism Risk

Researchers have found dozens of new genes that may play a role in causing autism, according to two studies published Wednesday in the medical journal Nature.

Scientists identified 60 genes with a greater than 90% chance of increasing a child's autism risk. Previous research has yielded only 11 genes that had been confirmed with this level of certainty.Though other studies have shown the importance of genetics in the development of autism, experts say these new studies zero in on the exact nature of the genetic mutations that cause the disorder
