What this trial studies

This study focuses on analyzing genetic variants found in individuals with psychiatric disorders such as schizophrenia, bipolar disorder, autism spectrum disorder, and resistant depression. It aims to investigate how these genetic variants are inherited within families and to explore their functional consequences in the cells of patients and their relatives. The study will enrich biocollections with DNA samples from blood or saliva, as well as hair follicles from participants, to facilitate further genetic analysis. Participants must be over 18 years old and affiliated with the social security system.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the genetic underpinnings of psychiatric disorders, potentially leading to improved diagnosis and treatment options.

How similar studies have gone: Other studies have shown promise in understanding genetic contributions to psychiatric disorders, making this approach both relevant and potentially impactful.
