Massive study to unravel genetic mysteries of aortic disease
NCT ID NCT04005976
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is gathering 5,000 people with certain gene changes that raise the risk of aortic disease (like aneurysms or dissections). Researchers will track their health over time to see how these genes affect the condition. The goal is to better predict and manage the disease, not to test a new treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients and their relatives with a confirmed pathogenic, likely pathogenic variant, or variant of unknown clinical significance in at least one of the H-TAD genes (i.e. TGFBR1, TGFBR2, SMAD3, TGFB2, TGFB3, ACTA2, MYH11, MYLK, PRKG1, MAT2A, MFAP5, LOX, COL3A1, FOXE3, and FBN1). * Patients of all ages, sex and race for which informed consent can be obtained. Exclusion Criteria: * Patients without a confirmed causative variant for H-TAD.
