Social Responsiveness Scale

Using an innovative statistical approach, a research team from the School of Medicine and the University of California, Los Angeles, has identified two regions of DNA linked to autism. They found the suspicious DNA with a much smaller sample of people than has been used traditionally in searches for autism genes.

Drawing by an autistic childA research team at the School of Medicine has identified regions of DNA that may be related to risk for autism. The researchers are learning how autism is inherited, and to identify genetic factors, they’re studying families and looking for traits that normally aren’t considered autistic but have connections to autism risk. Several studies have demonstrated that autism has a strong genetic component.
