Extensive Research Description

We are interested in studying the genetics of autism, regression and other childhood neurological disorders. Our primary focus is on Childhood Disintegrative Disorder (CDD), a rare form or autism in which a child is typically developing until at least age 3 and then experiences a major regression in which they lose skills such as social, language, play and toiletry. After regression, these children are diagnosis on the spectrum, and most with intellectual disorder. As regression is found in roughly 30% of children on the spectrum, we are interested in studying the potential genetic causes of regression as they may shed light on the biological pathways involved in CDD.
