The chi-square test was used to determine the association between MTHFD1 G1958A polymorphism and male infertility, using SPSS software.P?0.05 was considered significant.
A polymorphism in methylenetetrahydrofolate dehydrogenase 1 (MTHFD1), R653Q (MTHFD1 c.1958 G > A), has also been associated with increased birth defect risk, likely through reduced purine synthesis.
Our study suggests no significant genetic association of MTHFR (rs1801131, rs1801133) and MTHFD1 (rs8006686) polymorphisms in South Indian PEX patients.
The minor allelic frequencies of the MTHFD1 1958G>A and MTHFR 1298A>C in our populations were similar to those reported from Southeast Asian population, suggesting a possible explanation for the prevalence of this malformation in these regions.
This case-control study investigated the interactions of methylenetetrahydrofolate dehydrogenase 1 (MTHFD1)-1958G>A (rs2236225) and the methylenetetrahydrofolate reductase (MTHFR) - 677C>T (rs1801133) and 1298A>C (rs1801131) polymorphisms with the risk of AE in the Northeast Indian population.
In people, a single nucleotide polymorphism of this gene (1958G>A; rs2236225) is associated with increased risk for bipolar disorder and schizophrenia, neural tube and other birth defects.
Hyperactivity-impulsivity score revealed association with rs5742905 'TT' and rs2236225 'CC', while rs1801133 'CC' showed association with inattentiveness and hyperactivity-impulsivity. rs1801131 exhibited strong synergistic interaction with rs1051266 and rs2236225.

In the case-control study, those with the MTHFD1 G1958A variant were associated with around twofold risk of anencephaly (p=0.01) and spina bifida (p<0.01).
Associations of plasma serine and glycine concentrations with risk of AMI</span> across 2 common and functional MTHFD1 polymorphisms (rs2236225 and rs1076991) were explored in Cox regression models.
In the case-control study, those with the MTHFD1 G1958A variant were associated with around twofold risk of anencephaly (p=0.01) and spina bifida (p<0.01).
The haplotype GGGG, which consists of 4 SNPs (rs2236225, rs2236224, rs1256146, and rs6573559), is also associated with risk of NTDs (P value=0.0438, OR=0.7180, 95% CI=0.5214-0.9888).
Statistically significant associations were observed between CRC risk and functionally defined candidate SNPs of methylenetetrahydrofolate dehydrogenase 1 (MTHFD1; K134R), 5-methyltetrahydrofolate-homocysteine methyltransferase reductase (MTRR; P450R), and PR domain containing 2 with ZNF domain (PRDM2; S450N) and a literature candidate SNP of thymidylate synthase (TYMS; g.676789A>T; nominal P < .05).
Drinking water inorganic arsenic concentration was associated with increased risk of myelomeningocele for participants with 4 of the 14 studied single-nucleotide polymorphisms in genes involved in folate metabolism: the AA/AG genotype of rs2236225 (MTHFD1), the GG genotype of rs1051266 (SLC19A1), the TT genotype of rs7560488 (DNMT3A), and the GG genotype of rs3740393 (AS3MT) with adjusted odds ratio of 1.13, 1.31, 1.20, and 1.25 for rs2236225, rs1051266, rs7560488, and rs3740393, respectively.
The polymorphism of SNP loci rs1956545 and rs56811449 as well as a haplotype in MTHFD1 gene could serve as an indicator for the occurrence of NTDs in Chinese population and some specific genotypes of the loci may have lower risk of developing NTDs.
The haplotype GGGG, which consists of 4 SNPs (rs2236225, rs2236224, rs1256146, and rs6573559), is also associated with risk of NTDs (P value=0.0438, OR=0.7180, 95% CI=0.5214-0.9888).
The R134K and R653Q variants in MTHFD1 were genotyped in an Australian cohort of 520 unrelated migraineurs (162 were diagnosed with migraine without aura [MO] and 358 with MA) and 520 matched controls.
