| MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the 5-methyltetrahydrofolate-homocysteine methyltransferase. This enzyme, also known as cobalamin-dependent methionine synthase, catalyzes the final step in methionine biosynthesis. Mutations in MTR have been identified as the underlying cause of methylcobalamin deficiency complementation group G. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, May 2014]
PHENOTYPE: Mice homozygous for a targeted null mutation exhibit embryonic lethality prior to E9.5. Heterozygous appear mostly similar to conrtols, except that they exhibit elevated plasma methionine and homocysteine levels. [provided by MGI curators]
