KCNQ1 SNPs have been shown as a more significant contributor to type 2 diabetes than other loci in other Asian populations [40] and because both SNPs (in weak LD) with larger ORs are located on the same gene, it appears that KCNQ1 may truly have a stronger signal in South Asians than in white Europeans. Here, KCNQ1 is linked to type 2 diabetes mellitus.
