About
DDX3X syndrome is a genetic cause of intellectual disability and other neurologic features including, in some cases, autism. Variants in the DDX3X gene are thought to account for 1-3% of unexplained intellectual disability in females, making it one of the more common causes of intellectual disability.This study seeks to characterize DDX3X-related neurodevelopmental disorders using a number of genetic, medical and neuropsychological measures.
Full description
Subjects with a variant in the DDX3X gene will be asked to complete a battery of developmental, behavioral and medical assessments to better characterize gene-related neurodevelopmental deficits. This series of assessments takes place over the course of a three-day period. It includes the Autism Diagnostic Observation Schedule (ADOS), parent interviews regarding developmental history and behavior, a psychiatric evaluation, a neurology assessment, as well as a clinical genetic evaluation that includes a physical and vitals exam. Affected individuals, as well as biologically related siblings, will also undergo a series of sensory assessments, including a research EEG, visual evoked potential, and an eyetracking assessment. Family members present for the visit will also be asked to provide a blood and/or saliva sample for research genetics.
