Hence, in the present study we prioritized to evaluate previously identified common genetic variants in KCNJ11 (rs5219), TCF7L2 (rs7903146), SLC30A8 (rs13266634), IGF2BP2 (rs4402960), HHEX (rs1111875), CDKN2A (rs10811661), KCNQ1 (rs2237892), CDKAL1 (rs7754840) and FTO (rs8050136) for their association with T2D susceptibility. Here, KCNQ1 is linked to type 2 diabetes mellitus.
