Genetic Modifiers of 22q11.2 Deletion Syndrome

What this Trial Is About

22q11.2 deletion syndrome is a genetic disorder caused by the loss of a small part of chromosome 22. It can lead to a range of health issues including heart defects, facial abnormalities, immune deficiencies, kidney problems, hearing loss, developmental delays, learning disabilities, and increased risk of mental illnesses. The severity of symptoms varies widely among individuals, with some experiencing many problems and others having very few or none at all. This study seeks to understand why the severity differs by examining genetic variations in people with this syndrome. Participants will provide a sample of either blood or saliva during one study visit. Researchers will analyze the DNA from these samples to identify genetic differences that might influence how severe the disorder is in each person. This observational study does not involve treatments or interventions but focuses solely on genetic analysis. During the single visit, participants will undergo sample collection and may be asked to provide some medical history information. The main goal is to study the genetic material to find variations that could explain differences in symptom severity. There are no further visits or treatments, and the total time commitment is limited to the one study visit for sample collection and assessment.
