ASDs are now identified at a rate of 1:150 live children in the United States. Extensive research has identified various genetic disorders associated with ASD in approximately 10% to 15% of cases. The exponential growth of molecular genetic technologies has dramatically increased our ability to identify fundamental causes of the disorder. Such findings have a profound role in providing genetics counseling to families planning future offspring and in developing better treatment strategies.
