Global registry for genetic obesity

International Genetic Obesity Registry

Observational University of Ulm · NCT07296900

This registry collects health and genetic information from people with genetically confirmed or early-onset severe obesity to see if different genes relate to symptoms, complications, and treatment responses.

What this trial studies

The International Genetic Obesity Registry is an observational program that gathers clinical, genetic, and routine outpatient data from patients with monogenic or early-onset severe obesity. Participants provide consent and allow their medical records, genetic test results, and follow-up information to be entered into a centralized database. No experimental treatments are given; the registry documents natural history, comorbidities, and responses to standard therapies. The aggregated data aim to support research, inform clinical care, and help tailor management to specific genetic subtypes.

Who should consider this trial

Good fit: Ideal candidates are people with genetically confirmed genetic obesity (ACMG class 3-5 variants linked to obesity) or those with early-onset severe obesity who have had genetic testing, and who can provide informed consent (or whose guardians can consent).

Not a fit: People without genetic confirmation and those whose obesity is clearly non-genetic, as well as individuals unable to provide informed consent, are unlikely to benefit directly from this registry.

Why it matters

Potential benefit: If successful, the registry could lead to more accurate diagnosis, better subtype-specific guidance, and more personalized treatment options for people with genetic forms of obesity.

How similar studies have performed: Registries for rare genetic disorders have previously improved understanding of natural history and care, so this approach is established rather than novel.
