pervasive developmental disorder

Siblings of children with autism have more frequent language delays and other subtle characteristics of the disorder than previously understood. Girls also may be mildly affected more often than recognized in the past, according to a new study, led by researchers at Washington University School of Medicine in St. Louis.  

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.
