TCF7L2 and type 2 diabetes mellitus: The minor allele (‘T’) of SNPs (rs12255372 and rs7903146) of TCF7L2 gene showed significant susceptibility to T2D; however, in the present study after correction for multiple testing only the association between SNP rs7903146 and T2D remained statistically significant (P = 0.0001) (S1 Table).After Bonferroni correction, statistically significant association between the ‘C’ allele of theMC4R SNP rs17782313 and T2D was also observed (P = 0.00022) (S2 Table).
