SPARK -- a large database of DNA from people with autism and their families -- offers insight into the spectrum of the disorder.

Neuropsychologist Ericka Wodka of Kennedy Krieger Institute explains how the enormous number of SPARK participants helps researchers investigate other conditions that commonly affect people with autism. And Angie Auldridge, whose son, Mark, has autism, tells how genetic testing revealed a rare mutation and set his treatment on a different path.
