Abstract

We aims investigate Turkish type 2 diabetic patients with/without diabetic foot ulcers and healthy group and examined the contribution of the G/C exon 2 and T/C exon 6 of the PPARgamma gene polymorphism to the development of diabetic foot ulcers. The PPARgamma genotypes were determined prospectively in 50 patients with diabetic foot ulcers and 50 without diabetic foot ulcers and a control group of 50 healthy individuals. Genotyping of the G/C exon 2 and T/C exon 6 of the PPAR-gamma gene polymorphism for all individuals was performed by melting curve analysis of the generated amplicons after real-time online PCR. The genotype exon 2 and exon 6 distribution did not differ between the control group and the type 2 diabetes mellitus patients (with and without diabetic foot) (P>0.05). The frequency of the polymorphic G allele in exon 2 was no similar for the groups (6% and 1%, respectively) (p0.05). The evaluation of exon 2 and exon 6, genotype and haplotype did not show statistically significant difference between the patient diabetic foot and without diabetic foot (p>0.05). The G/C exon 2 and T/C exon 6 of the PPARgamma gene polymorphism is not an independent risk factor for diabetic foot in Turkish type 2 diabetes mellitus patients. Genetic factors in the pathogenesis of diabetic foot may also show any changes in different populations.
