WNT2B and type 2 diabetes mellitus: Results. In single-locus analysis, SNPs in four genes were significantly associated with T2D adjusted for multiple testing (rs7903146C in TCF7L2, p = 3.21∗10−3, OR = 1.39, 95% CI [1.31–1.47], rs12904944G in SMAD3, p = 2.51∗10−3, OR = 1.39, 95% CI [1.31–1.47], rs2273368C in WNT2B, p = 4.46∗10−3, OR = 1.23, 95% CI [1.11–1.32], rs6902123C in PPARD, p = 1.14∗10−2, OR = 1.40, 95% CI [1.32–1.48]).
