MTHFD1 encodes C1-tetrahydrofolate synthase, which is a folate-dependent enzyme that catalyzes the formation and interconversion of folate-activated one-carbon groups for nucleotide biosynthesis and cellular methylation. A polymorphism in MTHFD1 (1958G→A) impairs enzymatic activity and is associated with increased risk of adverse pregnancy outcomes, but the mechanisms are unknown.
