Observing metabolic profiles in patients with imprinting disorders
Official title: National Cohort on Imprinting Disorders and Their Metabolic Consequences
Run by Institut National de la Santé Et de la Recherche Médicale, France · NCT05945576 · Data updated 2026-11-12
This study looks at the metabolic health of people, both adults and children, with imprinting disorders to see if there are common patterns and how these conditions affect their overall health.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include both adults and children diagnosed with any imprinting disorder, regardless of disease severity.
✕Probably not a fit
Patients without a confirmed diagnosis of an imprinting disorder will not benefit from this study.

What this trial studies
This observational study aims to describe the natural history of imprinting disorders (IDs) by analyzing the metabolic profiles of affected patients, both adults and children. It seeks to identify common metabolic characteristics across various IDs, assess the impact of these disorders on metabolic health, and explore potential therapeutic approaches. Participants will be recruited from partner centers, and informed consent will be obtained from all subjects. The study will focus on conditions such as Silver Russell Syndrome, Beckwith-Wiedemann Syndrome, and others.
Why it matters
Potential benefit: If successful, this study could enhance the understanding of metabolic risks associated with imprinting disorders and improve clinical classification and prognosis.
How similar studies have gone: While there have been studies on individual imprinting disorders, this comprehensive approach to analyzing metabolic profiles across multiple IDs is relatively novel.
