rs7775228(T) was found to be associated with increased risk for osteoarthritis among Japanese, but not Europeans, with an odds ratio of 1.34 (CI: 1.21-1.49, combined p = 2.43×10e?8). This SNP is also in linkage disequilibrium with rs10947262, which was found to be associated in multiple populations with osteoarthritis.[PMID 20305777
