| Research Abstract |
To investigate the underlying genetic variants in EPAS1 and MMP13 in osteoarthritis, we conducted a case-control association study in Japanese population. 475 patients and 563 health individuals from two areas(Itabashi and Miyama) of Japan were genotyped using restriction fragment length polymorphism and TaqMan SNP Genotyping Assays. The allele frequencies of rs1703192 in EPAS1 and rs2252070 in MMP13 were significantly different between knee osteoarthritis patients and healthy controls. In Itabashi cohort analysis, rs1703192 was associated with knee osteoarthritis under allelic(χ2test : p=0. 018) and recessive model(p=0. 031). In the cohorts-combined analysis, the associations were observed in rs1703192 under allelic(p=0. 013) and recessive(p=0. 018) models, and in rs2252070 under recessive model(p=0. 039).
