Additional Study Information: The Translational Medicine Program at the Center for Autism and the Developing Brain is recruiting individuals with autism from 1 to 40 years of age and their biological family members from 1 - 70 years of age to participate in our Autism Biorepository. Participants will be given a travel reimbursement of $25 for 2 family members, $30 for 3 family members, and $40 for 4 or more family members.The purpose of this study is to determine genetic factors that influence the development of autism. The visit will likely take about 1-2 hours to go through the consent process, some behavioral questionnaires, and blood draws. If all available biological family members under the age of 70 are not able to come at the same time we can schedule multiple visits to accommodate people's schedules.
