Of the nine SNPs, GLIS3-rs7034200 was also significantly associated with type 2 diabetes (OR [95%CI]  = 1.27 [1.09–1.49], P = 0.003), IFG (OR [95%CI]  = 1.21 [1.07–1.36], P = 0.002), and combined IFG/type 2 diabetes (OR [95%CI]  = 1.23 [1.10–1.37], P = 0.0002) (Table 3). This evidence concerns the gene GLIS3 and type 2 diabetes mellitus.
