Maternal Mthfd1(gt/+) genotype impairs fetal growth but does not cause NTDs when dams are maintained on a folate- and choline-deficient diet. Mthfd1(gt/+) mice exhibit a spectrum of adverse reproductive outcomes previously attributed to the human MTHFD1 1958G→A polymorphism. Mthfd1 heterozygosity impairs folate status in pregnant mice but does not significantly affect homocysteine metabolism.
