How Genetic Is Cushing's Syndrome?
Genetics plays a meaningful role in Cushing's Syndrome, with heritability estimated at around 20%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Cushing's Syndrome: ARMC5 MEN1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
