MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a branched chain aminotransferase found in mitochondria. The encoded protein forms a dimer that catalyzes the first step in the production of the branched chain amino acids leucine, isoleucine, and valine. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]
PHENOTYPE: The metabolism of branched chain amino acid is impaired in homozygous null mice, resulting in a phenotype similar to human maple syrup urine disease. Mutants exhibit a failure to thrive and die prematurely, though the severity of the symptoms can be ameliorated with a restricted diet. [provided by MGI curators]
