Background: Meningioma is the second most common primary tumor of the central nervous system, and multiple genetic and environmental factors contribute to its etiology. Methylene tetrahydrofolate reductase (MTHFR) is a pivotal enzyme in folate metabolism. We conducted a case-control study to investigate the association of the MTHFR gene and meningioma in a Han population in northern China.
Methods: We genotyped two SNPs (C677T and A1298C) using polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). In this study 317 meningioma patients were compared to 320 normal controls. Data were analyzed by SPSS 13.0 and HaploView software.
Results: We found a significant difference in the frequency distribution of 677CC and 677TT between cases and control groups; another SNP exhibited no differences in any genotype between the two cohorts.
Conclusion: The results revealed that variations of the MTHFR gene were associated with meningioma; this finding indicates that the MTHFR gene potentially plays an important role in the pathogenesis of meningioma in the Northern Chinese Han population.
