None of the seven SNPs in genes involved with insulin production located in other genomic regions (Group 2) were associated with T2D in females; however, three SNPs (IGF2BP2 [rs4402960], TCF7L2 [rs7903146], and SLC30A8 [rs3802177]) were associated in males. Here, TCF7L2 is linked to type 2 diabetes mellitus.
