PPARGC1A and type 2 diabetes mellitus: These findings are similar to those from a study in Sichuan, China by Song et al.[28] Additionally, the present study detected no difference in the genotypes and allele distribution of the 3 SNPs of the PPARGC1A gene (rs8192678, rs3755863, and rs3736265) between the IFG+DM and NFPG groups even after adjusting for age, sex, BMI, and drinking status, suggesting that the polymorphisms of the PPARGC1A gene were not associated with IFG or T2DM.
