The influence of the Pro12Ala mutation of the PPAR-gamma receptor gene on metabolic and clinical characteristics in treatment-naäve patients with type 2 diabetes

Peroxisome proliferator activated receptor-gamma is an important factor in adipocyte differentiation and energy metabolism and is thus a candidate gene for obesity, insulin resistance and dyslipidaemia. We therefore assessed the associations between the most common variant of the PPAR-γ, the Pro12Ala (P12A) substitution in the PPAR-_γ2. gene, with BMI, blood pressure, fasting plasma glucose, HbA_1c, total cholesterol, LDL and HDL cholesterol and plasma triglyceride in 183 treatment-naïve patients with type 2 diabetes (T2D). The P12A allele associated with lower fasting plasma glucose but had no influence on HbA_1c, or BMI. In obese patients (BMI > 29 kg/m²), the P12A substitution associated with elevated total and non-HDL cholesterol levels.
