MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes L-2-hydroxyglutarate dehydrogenase, a FAD-dependent enzyme that oxidizes L-2-hydroxyglutarate to alpha-ketoglutarate in a variety of mammalian tissues. Mutations in this gene cause L-2-hydroxyglutaric aciduria, a rare autosomal recessive neurometabolic disorder resulting in moderate to severe mental retardation. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a hypomorphic allele exhibit increased levels of lysine and arginine associated with decreases in saccharopine, glutamine, and glutamate in adult brains, neurobehavioral deficits, and brain spongiosis with vacuolar lesions mostly affecting oligodendrocytes and myelin sheaths.
