Autism is no stranger to the genetics versus environment debate, and research has shown the answer likely lies in the middle — where both contribute to the diagnosis of autism spectrum disorder (ASD). ASD is considered a complex genetic disorder because even though numerous sibling studies have shown that genetics contribute to ASD, not all identical twins have ASD. Researchers know that something else is involved in the development of ASD for many individuals. Early finds from a recent Center for Autism Research (CAR) study zero in on a specific region of DNA that may be particularly important to ASD.
