Familial thyroid cancer accounts for ~5% of cases; germline RET mutations cause MEN2-associated medullary thyroid cancer. Common variants also contribute.
How Genetic Is Thyroid Cancer?
Genetics plays a meaningful role in Thyroid Cancer, with heritability estimated at around 53%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Thyroid Cancer: RET BRAF FOXE1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
