The relationship of the endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) gene polymorphism in Turkish type 2 diabetic patients with and without diabetic foot ulcers

Abstract

OBJECTIVEThis study aims to evaluate the influence of eNOS G894T and VEGF C936T gene polymorphism in diabetic foot ulcers. METHODWe studied 50 patients with diabetic foot ulcers and 57 diabetic patients without diabetic foot ulcer and a control group of 75 healthy individuals. RESULTSThe genotype eNOS distribution did not differ between Type 2 Diabetic Patients group and Diabetic Foot Ulcer group (P>0.05). The frequency of the polymorphic T allele in Type 2 Diabetic Patients were significantly higher than the control group (42.3% and 24.5%, respectively)(p<0.01). The frequency of the polymorphic T allele between the Type 2 Diabetic Patients and Diabetic Foot Ulcer group was similar (p>0.05). The genotype VEGF distribution did not differ between Type 2 Diabetic Patients group and Diabetic Foot Ulcer group (P>0.05). The frequency of the polymorphic T allele between the Type 2 Diabetic Patients and Diabetic Foot Ulcer group was similar for both groups (p>0.05). CONCLUSIONPolymorphism of eNOS G894T is not a risk factor for diabetic foot ulcer formation. T allele is a risk factor for diabetes, but T allele is not a risk factor for diabetic foot ulcer formation. Polymorphism of VEGF C936T and T allele are not risk factors for diabetes occurence and diabetic foot formation.
