Cushing syndrome caused by cortisol excess is mostly sporadic. Familial forms occur in Carney complex (PRKAR1A mutations) and MEN1 syndrome.
How Genetic Is Cushing Syndrome?
Genetics plays a meaningful role in Cushing Syndrome, with heritability estimated at around 10%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Cushing Syndrome: PRKAR1A,MEN1,APC. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
