Aortic aneurysm is an abnormal bulging of the aorta. Familial forms exist and several connective tissue disorders associated with gene mutations dramatically increase risk.
How Genetic Is Aortic Aneurysm?
Genetics plays a meaningful role in Aortic Aneurysm, with heritability estimated at around 54%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Aortic Aneurysm: FBN1,MYH11,ACTA2,SMAD3. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
