Addison's disease is an autoimmune adrenal insufficiency. It has a significant genetic basis with HLA genes being major determinants of susceptibility.
How Genetic Is Addison's Disease?
Genetics plays a meaningful role in Addison's Disease, with heritability estimated at around 40%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Addison's Disease: HLA-DQ2,HLA-DR3,CTLA4. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
