An analysis of the common SNPs in T2D patients and matched controls identified three T2D-associated loci in the noncoding regions near CDKN2A and CDKN2B, introns of IGF2BP2 and CDKAL1, as well as replication associations near HHEX and SLC30A8. T2D-related loci were also identified and confirmed in noncoding regions by analyzing common SNPs in T2D patients and matched controls [19]. Here, CDKN2B is linked to type 2 diabetes mellitus.
