We investigated the association between 12 single nucleotide polymorphisms (SNPs) in 11 genes involved in folate metabolic and preterm birth. A subset of SNPs selected from 11 genes/loci involved in the folic acid metabolism pathway were subjected to SNaPshot analysis in a case-control study. Twelve SNPs (CBS-C699T, DHFR-c594+59del19, GST01-C428T, MTHFD-G1958A, MTHFR-C677T, MTHFR-A1298C, MTR-A2756G, MTRR-A66G, NFE2L2-ins1+C11108T, RFC1-G80A, TCN2-C776G, and TYMS-1494del6) in 503 DNA samples were simultaneously tested, and included 315 preterm births and 188 controls. None of the 12 SNP genotype distributions related to the folic acid metabolism pathway showed a significant difference between preterm and term babies. The frequency of the compound mutation genotype of MTHFD-G1958A, MTR-A2756G and RFC1-G80A in preterm babies was 7.3%, which was significantly higher than the 2.7% in term babies. Seven babies carried the compound mutation genotype of MTHFD-G1958A, MTR-A2756G, and CBS-C699T, but this was not observed in term babies. The frequency of the combined wild-type genotype of MTHFD-G1958A, MTR-A2756G, MTRR-A66G, MTHFR-A1298C, NFE2L2-ins1+C11108T, and RFC1- G80A in preterm babies was 3.17%, which was significantly lower than the 7.4% in term babies. The 12 SNPs screened in this study were not independent risk factors of preterm birth. Compound mutation genotypes, including MTHFD-G1958A, MTR-A2756G, and RFC1- G80A and MTHFD-G1958A, MTR-A2756G, and CBS-C699T, may increase the risk of preterm birth. The combined wild-type genotype MTHFD-G1958A, MTR-A2756G, MTRR-A66G, MTHFR-A1298C, NFE2L2-ins1+C11108T, and RFC1-G80A may decrease the risk of preterm birth.
