Autism Spectrum Disorder (ASD) and Intellectual Disability (ID) Determinants in Tuberous Sclerosis Complex (TSC)

Active Not RecruitingN/A

Sponsor: Boston Children's Hospital

Conditions: Tuberous Sclerosis, Autism Disorder, Intellectual Disability

Countries: United States

The purpose of this study is to characterize the developmental phenotype of ASD and ID and to identify biomarkers using advanced MRI methodology and electrophysiological biomarkers of synaptic function and connectivity predictive of ASD and ID presence and severity in patients with TSC. In addition, this study will be establishing infrastructure for the collection and storage of human bio-specimens, including genetic material, from TSC patients and their family members with ASD.
