We validated three variants for T2D namely, rs11634397 at ZFAND6 (OR = 3.05, 95%CI = 1.02–9.19, p = 0.047) and rs8042680 at PRC1 (OR = 3.67, 95%CI = 1.13–11.93, p = 0.031) showing higher risk and rs6813195 at TMEM154 (OR = 0.28, 95%CI = 0.09–0.90, p = 0.033) showing protective effect. This evidence concerns the gene TMEM154 and type 2 diabetes mellitus.
