Study Description

Brief Summary: The purpose of this study is to determine cross-sectional and longitudinal medical, behavioral, and cognitive differences between PTEN ASD and other groups, as well as to identify cognitive, neural systems, and molecular biomarkers specific to PTEN ASD. In addition, this study will be creating and maintaining a biorepository and linked phenotypic database for PTEN ASD.

Detailed Description: Autism spectrum disorders (ASD) are a set of neurodevelopmental disorders characterized by social communication/interaction impairments and restricted/repetitive behaviors. ASD associated with germline heterozygous PTEN mutations (PTEN ASD) is a genetically defined sub-group that, may be one of the more prevalent genetic disorders contributing to ASD (0.5-2%). The purpose of this research study is to carefully track the phenotypic and molecular characteristics of PTEN ASD and identify biomarkers for intervention studies. Individuals with PTEN ASD, with macrocephalic ASD without a PTEN mutation (macro-ASD), healthy controls, and individuals with PTEN mutations without ASD (PTEN no-ASD) will be asked to participate in this study if they are 18 months and older. Both males and females will be asked to participate. Additionally, to be eligible for study participation, individuals' primary communicative language must be English. The study involves 3 on site visits over the course of two years. Study visits will vary in length from about 4 hours to 6 hours. Study visits involve a physical exam, medical history questions, neuropsychological assessments, and a blood draw done for laboratory studies. A subset of participants between the ages of 2 and 11 years old will take part in the EEG portion of the study. Individuals who have a clinically indicated MRI will have an option to provide routine clinical scans for analysis.
