This group is more homogeneous than many others. We hope to identify specific genes that predispose children to develop autism. By identifying those genes we can try to understand the general neurodevelopmental processes that lead to the development of autism. Researchers are not looking for simple answers, Risch explained. We don't think of autism as one dominant gene disorder.
Autism is genetically more complicated.
We are likely dealing with multiple genes. We have a strong suspicion that genetic factors play a part in autism. Both biological parents and the affected child must be willing and available to have a blood sample drawn. The study, which has just gotten under way, is multifaceted. In the clinical segment, families will be interviewed and receive individual diagnoses.
