The California Autism Twin Study (CATS)
07/2004 - 06/2009

The California Autism Twin Study (CATS) seeks to study the behavior and learning styles of children with autism and their twins. The study will enroll families with twins throughout California in order to learn whether some characteristics of autism, including impairments in social interaction, language and learning are shared between twins.  By evaluating twins where one or both twins has autism, researchers hope to find out which characteristics of autism are influenced more by genes and which are caused more by something else.  Scientists from Stanford University, Kaiser Permanente, University of California, San Francisco, Autism Genetic Resource Exchange (AGRE), the Medical Investigation of Neurodevelopmental Disorders Institute (M.I.N.D), and California CADDRE are collaborating on this study. The study is being funded by the National Institute of Mental Health (NIMH).
