Four risk alleles for SLC30A8, CDKN2A/B, CDC123, and KCNQ1 were significantly associated with T2DM (P < 0.05), although three of them were not significant when Bonferroni's correction for multiple testing applied (significance level, 0.05/17 = 0.0029). This evidence concerns the gene CDC123 and type 2 diabetes mellitus.
