MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes one of five subunits of eukaryotic translation initiation factor 2B (EIF2B), a GTP exchange factor for eukaryotic initiation factor 2 and an essential regulator for protein synthesis. Mutations in this gene and the genes encoding other EIF2B subunits have been associated with leukoencephalopathy with vanishing white matter. [provided by RefSeq, Nov 2009]
PHENOTYPE: Mice homozygous for a knock-in allele exhibit abnormal brain white matter development, decreased body fat, demyelination, impaired recovery from cuprizone-induced demyelination, and impaired coordination. [provided by MGI curators]
