This study examines adults with COL5A gene mutations to understand why some develop aortic aneurysms while others do not. Participants provide a small skin biopsy, and researchers analyze fibroblasts to evaluate collagen production, extracellular matrix organization, and connective-tissue signaling pathways. The goal is to identify biological differences that may explain variable vascular risk and support future personalized monitoring and treatment strategies.
Subjects aged 18 and above
