ObjectiveACE I/D and MTHFR C677T gene polymorphisms can be seen as candidate genes for glioma on the basis of their biological functions and their involvement in different cancers. The aim of this study was to analyze potential association and overall survival between MTHFR C677T and ACE I/D polymorphism in glioma patients in our population.Materials and methodsWe tested genotype distribution of 112 glioma patients against 141 cancer-free controls from the same region. Kaplan-Meier survival analysis was performed to evaluate overall survival of patients for both genes.ResultsNo significant differences were found among MTHFR C677T wild type C and variant genotypes CT/TT with glioma patients. In ACE, the distribution of variant ID and DD was found to be significantly higher in glioma cases as compared to controls (p<0.0001). ACE DD genotypes were highly presented in glioma cases 26.8% versus 10.6% in controls (p<0.0001) and conferred 5-fold risk for predisposition in glioma cases. Per copy D allele frequency was found higher in cases than in controls (0.54 versus 0.25: p<0.0001). Interestingly we found a significant overall survival (with log rank p<0.01) in patients who presented with ACE DD genotypes had the least estimated overall survival of 13.4months in comparison to 21. 7 and 17.6months for ACE II and I/D genotypes respectively.ConclusionWe conclude ACE I/D polymorphism plays a vital role in predisposition of higher risk for glioma. We also suggest that ACE DD genotypes may act as an important predictive biomarker for overall survival of glioma patients.
