- Abstract
- AIMS: We examined whether the common polymorphisms of the peroxisome proliferator-activated receptor-gamma (PPARgamma) gene are associated with Type 2 diabetes or obesity in the Korean population. METHODS: We genotyped two common PPARgamma polymorphisms (Pro12Ala and 161C > T) and examined their association with the clinical phenotypes found in 684 patients with Type 2 diabetes mellitus and 291 non-diabetic control subjects. RESULTS: The 12Ala allele was less frequent in the Type 2 diabetic patients than in the non-diabetic control subjects (0.036 vs. 0.053, P = 0.024). The allele frequencies of the 161C > T polymorphism did not differ between the control and Type 2 diabetic group (0.158 vs. 0.173). In the non-diabetic controls, those with the T allele had lower BMI and fasting serum triglyceride (TG) concentrations than those with the C/C homozygote (22.7 +/- 2.9 vs. 23.8 +/- 3.2 kg/m2, P = 0.002; 1.45 +/- 0.81 vs. 1.65 +/- 0.83 mmol/l, P = 0.03, respectively). The 12Ala-161T haplotype was associated with a decreased risk for Type 2 diabetes (OR = 0.47, P = 0.009), whereas the 12Pro-161T haplotype was associated with lower BMI and lower fasting serum TG (22.5 +/- 2.8 vs. 23.7 +/- 3.2 kg/m2, P = 0.004; 1.41 +/- 0.87 vs. 1.64 +/- 0.79 mmol/l, P = 0.02, respectively). CONCLUSIONS: The PPARgamma 12Ala allele was associated with a reduced risk of Type 2 diabetes, whereas the PPARgamma 161T allele was associated with lower BMI and fasting serum TG concentrations in the Korean subjects. The subjects with 12Ala-161T haplotypes had a reduced risk of Type 2 diabetes.
