Autoimmune thyroid diseases including Graves disease and Hashimoto's thyroiditis have heritability of approximately 70–80%.
How Genetic Is Autoimmune Thyroid Disease?
Genetics plays a meaningful role in Autoimmune Thyroid Disease, with heritability estimated at around 70%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Autoimmune Thyroid Disease: HLA-DR3,CTLA4,PTPN22,TSHR. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
