Genetic variants in CDKN2A/B, CDKAL1, TCF7L2, TCF2, MC4R, and PPARG showed a nominal association with type 2 diabetes (P≤0.05), of whom the three first would stand correction for multiple testing: CDKN2A/B rs10811661, OR: 1.26 (1.12–1.43) P = 1.8*10−4; CDKAL1 rs10946398, OR: 1.23 (1.09–1.39); P = 7.1*10−4, and TCF7L2 rs7903146, OR: 1.61 (1.19–2.18) P = 2.3 * 10−3. This evidence concerns the gene CDKAL1 and type 2 diabetes mellitus.
