Rare genetic condition may disrupt fat tissue, raising diabetes risk
NCT ID NCT07516496
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether people with vascular Ehlers-Danlos syndrome (vEDS), a rare genetic disorder that weakens blood vessels, also have problems with how their body stores and uses fat. Researchers will compare 12-17 adults with vEDS to similar adults without the condition using body scans, blood tests, and a sugar-drink test. The goal is to understand if vEDS affects fat tissue and increases the risk of insulin resistance and diabetes.
