Fifty healthy subjects served as controls. Materials and Methods: Genotypes were de­termined using polymerase chain reaction followed by restriction fragment length poly­morphism analysis. The restriction enzyme for the MTHFR C677T variants was HinfI. Results: No statistically significant differences were seen between the allelic and genotypic distribution of the MTHFR polymorphism. Conclusions: Additional studies with larger sample sizes are needed to define the influence of MTHFR C677T genotyping on clinical outcomes in renal allograft recipients.en-USMTHFRAssociationChronic allograft dysfunctionIranianGeneticArticle612146-8427
