Genetic Markers and Biomarkers in Patients With Intellectual Disabilities of Genetic Origin

Not Applicable

Recruiting

• Conditions: Down Syndrome; Intellectual Disability

• Registration Number: NCT05767203
• Lead Sponsor: Institut Jerome Lejeune

Brief Summary

Analyze genetic and biological markers in patients with Intellectual Deficiencies (ID) of genetic origin in order to better understand the mechanisms of modified genes, cellular mechanisms, pathways involved in different disorders , complications and pathologies associated with ID of genetic origin.

Detailed Description

Blood and skin samples will be taken from patients coming at the outpatients clinic of the Institut Jérôme Lejeune and who consent to participate to the study. Search and identification of markers will be then done from the collected samples.
