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.
