. Published 2013. this article discussed the SNP risk for osteoarthritis in a selenium-deficient region, following up on the 2010 study also cited here. "Kashin-Beck disease (KBD) is a kind of degenerative osteoarthropathy." It found that "Haplotypes TCC, TTC and TTT of rs1050450, rs1800668 and rs3811699 in GPX1 showed a significant association with KBD and controls with P value of 0.0421, 5.0E-4 and 0.0066, respectively." (Abstract) . Published 2010, this article discussed the SNP risk for osteoarthritis in a selenium-deficient region. "Kashin-Beck disease (KBD) is a disabling osteoarthropathy involving growth cartilage endemic to selenium (Se)-deficient regions in China." "Four polymorphisms including GPX1 (rs1050450), TrxR2 (rs5748469), SEPP1 (rs7579) and DIO2 (rs225014) were analyzed for 161 KBD patients and 312 controls." However, Only GPX1 (rs1050450) polymorphisms that were heterozygote proline/leucine or homozygote leucene/leucene conferred a risk compared with the other variant: "odds ratio=1.781; 95% confidence interval: 1.127-2.814." "No association was observed between the other three single nucleotide polymorphisms (SNPs) and KBD risk." .
