Phenotypic and Genetic Factors in Autism Spectrum Disorders
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

The purpose of the study is to collect phenotypic (observable characteristics) and genetic information about individuals with Autism Spectrum Disorders (ASDs) and their families.
Condition or disease
Autism Spectrum Disorders
Participation in this research study involves two research visits, at least one of which is at Children's Hospital Boston. The first visit lasts about 4-6 hours. On this visit, the child will work with a research assistant on a few different cognitive assessments while one or both parents answer interview questionnaires about the child's development, along with other family history information. The second visit at the hospital lasts about 2 and a half hours and involves medical history and family history questionnaires, as well as height, weight, and head circumference measurements and a blood draw from each family member. In addition, digital photographs will be taken of each family member and a 3-D picture of the child's face will be taken. Shortly after the visits, participants will receive a research report of our observations. These results include cognitive, behavioral, developmental, and social findings. The total time commitment for the study is 6 to 8 hours.
