MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Dihydrofolate reductase converts dihydrofolate into tetrahydrofolate, a methyl group shuttle required for the de novo synthesis of purines, thymidylic acid, and certain amino acids. While the functional dihydrofolate reductase gene has been mapped to chromosome 5, multiple intronless processed pseudogenes or dihydrofolate reductase-like genes have been identified on separate chromosomes. Dihydrofolate reductase deficiency has been linked to megaloblastic anemia. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2014]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit lethality soon after E14.5 with reduced size, pallor, impaired hematopoiesis and abnormal folic acid levels. Mice heterozygous for this allele exhibit abnormal folic acid levels, abnormal hemopoiesis and reduced endothelium-dependent vasorelaxation. [provided by MGI curators]
