MTHFE/C677T polymorphisms affect MTHFR enzyme activity with subsequent elevation in the toxic homocysteine concentrations that result in vasculopathy and nerve ischemia. This case control study was planned to estimate the association between the MTHFR/C677T polymorphism and the occurrence of peripheral neuropathy in type 2 diabetic (T2DM) patients in a group of Iraqi peopleEighty three Iraqi subjects were included in this study, 36 had diabetic peripheral neuropathy, 25 without peripheral neuropathy and 22 were healthy control.Genomic DNA was isolated from fresh whole blood and genotyped using the polymerase chain reaction–based restriction fragment length polymorphism assay for the MTHFR gene C677T mutation.The distribution of MTHFR/ C677T mutated genotypes between DPN and healthy groups was statistically differed with increased risk of occurrence of DPN (OR= 3.1, 95% CI: 1.02-9.4, p=0.05), while this risk was highly increased by seven folds when comparing DPN group with those without DPN& 2 (OR= 6.7, CI=2.1-20.8, p=0.0008).MTHFR/C677T polymorphism is highly associated with development of peripheral neuropathy in T2DM Iraqi population
