The MALDI-TOF-MS(matrix assisted laser desorption ionization time of flight mass spectrometry)method was used for genotyping of SNP loci in PPARG gene, detection and analysis of 100 cases of(50 controls, 50 cases)unrelated Kirgiz populations, to investigate the relationship between the SNPs of PPARG gene with type 2 diabetes mellitus(DM)in Xinjiang Kirgiz population. The results showed that 23 SNPs have polymorphism(MAF≥0.05)among the selected 31 SNP loci. There were statistical differences in blood pressure, hip circumference, blood sugar, TH, and LDL between the case and control groups(P<0.01). There were significant differences in genotypes and allele frequency distribution of SNPs rs1801282, rs1899951, rs2881654, and rs2972162 between the case and control groups(P<0.05). Logistics regression analysis displays significant differences in allele frequency between the two groups (OR value is 2.639, 2.639, 1.774, 2.639, P<0.05). There were significant differences in genotypes frequency of SNPs rs1899951, rs2292101, rs2881654, rs6782475, and rs1801282 between the men and women control group(P<0.05). The results also showed that the PPARG gene SNPs rs1801282, rs1899951, and rs2881654 have correlation with type 2 DM in Xinxiang Kirgiz people.
