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. The gene discussed is CDKN2A; the disease is type 2 diabetes mellitus.
