CircleDNA's Premium Test includes personalised reports on Graves Disease risk. See your genetic risk →
Graves disease is the most common cause of hyperthyroidism. It has a heritability of approximately 79% and is significantly more common in women.
How Genetic Is Graves Disease?
Genetics plays a meaningful role in Graves Disease, with heritability estimated at around 79%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Graves Disease: TSHR,HLA-DR3,CTLA4. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Graves Disease?
Family history does matter. Having close relatives with Graves Disease can increase your personal risk, though it is not deterministic. Maintaining a healthy lifestyle and regular screening remain important regardless of family background.
Frequently Asked Questions
Is Graves Disease genetic?
Genetics plays a role, but environment and lifestyle also contribute. Studies suggest heritability of approximately 79%. Key genes involved include TSHR,HLA-DR3,CTLA4.
Can a DNA test reveal my risk of Graves Disease?
Yes — DNA tests such as CircleDNA's Premium Test include reports on Graves Disease risk based on your genetic variants.
Does family history matter for Graves Disease?
Family history does matter for Graves Disease, though it is not deterministic — lifestyle and screening remain important regardless of family background.
Is Graves Disease hereditary, meaning it's passed directly from parent to child?
Graves Disease follows a multifactorial inheritance pattern in cases with a clear genetic cause, though not every case is inherited directly from a parent — some arise from new (de novo) mutations or a combination of genetic and environmental factors.
