Hypothyroidism occurs when the thyroid gland produces insufficient thyroid hormone. Autoimmune forms (Hashimoto's thyroiditis) have significant hereditary components.
How Genetic Is Hypothyroidism?
Genetics plays a meaningful role in Hypothyroidism, with heritability estimated at around 67%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Hypothyroidism: TSHR,TPO,FOXE1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
