All three SNPs, including rs13266634, rs3802177 and rs11558471 in the SLC30A8 gene were strongly associated with T2D in this study; however, rs3802177 had the most significant assocaition with T2D among the three SNPs with an adjusted p value of 1.22 × 10-8 and an odd ratio of 1.58 when a recessive model was tested. The gene discussed is SLC30A8; the disease is type 2 diabetes mellitus.
