Association Between Mthfr Gene Polymorphism And Ntds In Chinese Han Population
INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL MEDICINE(2014)
Abstract
Objective: This study aims to investigate the single nucleotide polymorphisms (SNPs) of 5,10-methylenetetrahydrofolate reductase (MTHFR) gene and neural tube defects (NTDs) in Chinese population. Method: A total of 271 NTDs cases and 192 healthy controls were used in this study. Fifty-two selected single nucleotide polymorphism (SNP) sites in the MTHFR gene were analyzed with next-generation sequencing method. A series of statistical methods were carried out to investigate the correlation between the SNPs and the patient susceptibility to NTDs. Results: Statistical analysis showed a significant correlation between the SNP sites rs1801133 in MTHFR gene and NTDs. The GG genotype, G allele of rs1801133 in MTHFR significantly decreased the incidence of NTDs (OR = 0.449, 95% CI: 0.255-0.789 with genotype, and OR = 0.669, 95% CI: 0.508-0.881 with allele). Conclusions: The gene polymorphism loci rs1801133 in MTHFR gene maybe potential risk factors for NTD in Chinese population.
