Özet:

Abstract We aims investigate Turkish type 2 diabetic patients with/without diabetic foot ulcers and healthy group and examined the contribution of the Pro12Ala exon 2  and C478T exon 6 of the PPARgamma gene polymorphisms 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 Pro12Ala exon 2 and C478T exon 6 of the PPAR-gamma gene polymorphisms for all individuals was performed by PCR-RFLP method. 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) (p<0.05). The frequency of the polymorphic T allele in exon 6 was similar for the groups (p>0.05). 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 Pro12Ala exon 2 and C478T exon 6 of the PPARgamma gene polymorphisms are 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. Key words: Peroxisome Proliferator Activated Receptor Gene Polymorphism, Type 2 Diabetic Patients, diabetic foot ulcers
