Here, we have studied theassociation of SNPs of folate metabolizing genes with the primary brain tumors (glioma and meningioma) in North Indianpopulation. Methods: SNPs of genes coding for folate metabolizing enzymes was carried out in 288 study populationfrom North India [Glioma (n=108), Meningioma (n=76) and healthy-control (n=104)]. The allele-specific polymerasechain reaction (ARMS-PCR) was used to analyse the SNP A1298C of the MTHFR (Methylenetetrahydrofolate-reductase)and the SNP A66G of the methionine synthase reductase (MTRR) genes. The PCR-RLFP (Restriction Fragment LengthPolymorphism) was used to analyse the SNP C677T of the Methylene tetrahydrofolate-reductase and the SNP A2756Gof the methionine-synthase (MTR) genes. Serum homocysteine, vitamin B12 and folate levels were evaluated in controls/patients serum using Chemiluminescence immunoassay and the levels were correlated with SNPs genotype. Results:The CC genotype of MTHFR A1298C was observed to have reduced risk of having meningioma than AA genotype(odd ratio=0.62, 95%CI 0.32-0.97, p=0.03). Similarly, the AG genotype of MTRR A66G showed reduced risk ofglioma than AA genotype (odd ratio=0.56, 95%CI 0.32-0.97, p=0.039). Furthermore, in patients with AA genotype ofMTR A2756G and CT genotype of MTHFR C677T showed higher serum homocysteine level than GG genotype (8.6μmol/L, p=0.048) and CC genotype (11.2μmol/L, p=0.039) respectively. Conclusion: Our findings provide an insightinto the risk association of SNPs in MTHFR A1298C and MTRR A66G genes with glioma/meningioma patients.Further studies are needed to evaluate their clinical implications.
