The MTHFD1 c.1958 G>A polymorphism and recurrent spontaneous abortions

Area of Science:

• Genetics
• Reproductive Biology
• Molecular Biology

Background:

• Recurrent spontaneous abortion (RSA) is a complex condition with multifactorial causes.
• The MTHFD1 gene plays a crucial role in DNA synthesis and folate metabolism, processes vital for successful pregnancy.
• Single Nucleotide Polymorphisms (SNPs) in genes like MTHFD1 are potential candidates for influencing RSA risk.

Purpose of the Study:

• To investigate the potential association between the c.1958 G>A Single Nucleotide Polymorphism (SNP) in the MTHFD1 gene and recurrent spontaneous abortions (RSA).
• To determine if variations in MTHFD1 genotype frequencies differ between women with RSA and healthy controls.

Main Methods:

• Genotyping of the c.1958 G>A SNP in the MTHFD1 gene was performed using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP).
• A cohort of 131 women diagnosed with at least two consecutive spontaneous abortions (cases) was compared to a matched control group of 131 women.

Main Results:

• The allele frequency for the A allele was 44.3% in patients and 42.4% in controls.
• The allele frequency for the G allele was 55.7% in patients and 57.6% in controls.
• Statistical analysis revealed no significant difference in allele frequencies between the RSA patient group and the control group.

Conclusions:

• The study found no significant difference in the allele frequencies of the MTHFD1 c.1958 G>A SNP between women with recurrent spontaneous abortions and controls.
• These results suggest that this specific MTHFD1 SNP is unlikely to be a major genetic contributor to the etiology of recurrent spontaneous abortions.
• Further research may explore other genetic or environmental factors implicated in RSA.
