7901: Autism Spectrum Disorder (ASD) and Intellectual Disability (ID) Determinants in Tuberous Sclerosis Complex (TSC)

Status: Closed to Enrollment

 

Study Summary

The goal of this research study is to learn more about children and young adults who have tuberous sclerosis complex (TSC) with autism spectrum disorder (ASD), TSC with intellectual disability (ID) or TSC with both. People with TSC have a higher chance of getting ASD, also called autism, as well as ID. Researchers in this study are trying to find earlier signs of autism and ID and gain a better understanding of ASD/ID in individuals with TSC so that effective treatments and interventions for ASD/ID can be found.

For Diseases: Tuberous Sclerosis Complex, Autism Spectrum Disorder, Intellectual Disability

 

Background

TSC is a multi-system disease that can present in many different ways both among and within families. About 50% of individuals with TSC develop ID and/or ASD. The purpose of this research study is to learn more information about ASD/ID in individuals with TSC through neurobehavioral assessments and magnetic resonance imaging (MRI) so that new and effective treatments and interventions for ASD/ID can be discovered.

 

About this Study

This is a longitudinal study of 100 individuals with TSC and ASD/ID. Individuals with TSC will be asked to participate in this study if they are between the ages of 3 and 21 years old and have been diagnosed with suspected or confirmed ASD and/or ID. Both males and females will be asked to participate. To be eligible for study participation, individuals’ primary language must be English. Additionally, the subject and at least one biological parent must be willing to provide a blood sample for the TSC biorepository.

The study involves 5 visits over the course of two years. Study visits will vary in length, lasting from about 4 hours to 6 hours. Study visits involve a physical exam, medical history questions and neuropsychological assessments. There will also be a blood draw at one time point during the study. Individuals with TSC have annual MRI scans as clinically indicated. The clinical scan will be 15 minutes longer as part of this study.

This study is taking place at 5 institutions throughout the country: Boston Children's Hospital, Cincinnati Children’s Hospital Medical Center, University of Alabama at Birmingham, University of Texas at Houston and University of California at Los Angeles.
