Analyzing genetic markers in patients with intellectual disabilities

Official title: Search for Genetic Markers and Biomarkers to Follow Patients With Intellectual Disabilities of Genetic Origin and to Understand Its Origin and Associated Comorbidities

Run by Institut Jerome Lejeune · NCT05767203 · Data updated 2026-11-12

This study is trying to learn more about the genetic causes of intellectual disabilities, like Down Syndrome, by looking at blood and skin samples from patients to find better ways to diagnose and treat these conditions.

What this trial studies

This study aims to analyze genetic and biological markers in patients diagnosed with intellectual disabilities of genetic origin, such as Down Syndrome. Blood and skin samples will be collected from participants at the Institut Jérôme Lejeune, where researchers will identify and study the mechanisms of modified genes and the cellular pathways involved in these disorders. The goal is to enhance understanding of the complications and pathologies associated with genetic intellectual disabilities. This research could lead to improved diagnostic and therapeutic strategies for affected individuals.

Why it matters

Potential benefit: If successful, this study could provide insights that lead to better management and treatment options for patients with intellectual disabilities of genetic origin.

How similar studies have gone: While this approach is focused on genetic markers in intellectual disabilities, similar studies have shown promise in understanding genetic conditions, suggesting potential for success.
