Research to identify genetic causes of rare diseases
Official title: Diagnostic Research in Patients With Rare Diseases -Solving the Unsolved Rare Diseases
Run by Centre Hospitalier Universitaire Dijon · NCT04024774 · Data updated 2026-11-12
This study is trying to find the genetic causes of rare diseases in patients by looking closely at their DNA and their family members' DNA to help improve diagnosis.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals with rare diseases of unclear genetic origin and their healthy parents for trio analysis.
✕Probably not a fit
Patients without a suspected genetic cause or those not affiliated with a national health insurance scheme may not benefit from this study.

What this trial studies
This observational study focuses on patients with rare diseases that have unclear molecular causes. It employs advanced algorithms and statistical models to re-analyze existing genetic data, complemented by omics technologies and functional studies using patient-derived cell lines. The study also includes a trio analysis involving healthy family members to enhance the identification of de novo variants. The goal is to improve the diagnosis of hereditary diseases that have previously remained unsolved.
Why it matters
Potential benefit: If successful, this research could lead to more accurate diagnoses for patients with rare genetic diseases.
How similar studies have gone: Other studies utilizing advanced genetic analysis techniques have shown promise in identifying previously undiagnosed rare diseases, indicating potential success for this approach.
