CircleDNA's Premium Test includes personalised reports on Osteoarthritis risk. See your genetic risk →
Osteoarthritis is the most common form of arthritis affecting the joints. Twin studies suggest 40–65% heritability with multiple genes contributing small effects.
How Genetic Is Osteoarthritis?
Genetics plays a meaningful role in Osteoarthritis, with heritability estimated at around 50%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Osteoarthritis: GDF5,TGFB1,COMP. 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 Osteoarthritis?
Family history does matter. Having close relatives with Osteoarthritis 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 Osteoarthritis genetic?
Genetics plays a role, but environment and lifestyle also contribute. Studies suggest heritability of approximately 50%. Key genes involved include GDF5,TGFB1,COMP.
Can a DNA test reveal my risk of Osteoarthritis?
Yes — DNA tests such as CircleDNA's Premium Test include reports on Osteoarthritis risk based on your genetic variants.
Does family history matter for Osteoarthritis?
Family history does matter for Osteoarthritis, though it is not deterministic — lifestyle and screening remain important regardless of family background.
Is Osteoarthritis hereditary, meaning it's passed directly from parent to child?
Osteoarthritis 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.
