Of these, we found significant evidence for association between T2D and SNPs at TCF7L2 in our Sudanese population, and suggestive evidence for associations at SNPs in CAPN10 and HHEX. Given the limitations of our sample size, we cannot discount the possibility that further associations with SNPs in more of these genes would be found in this population if larger sample sizes were employed. This evidence concerns the gene TCF7L2 and type 2 diabetes mellitus.
