Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
