Summaries for EIF2B3 Gene

Entrez Gene Summary for EIF2B3 Gene

  • The protein encoded by this gene is one of the subunits of initiation factor eIF2B, which catalyzes the exchange of eukaryotic initiation factor 2-bound GDP for GTP. It has also been found to function as a cofactor of hepatitis C virus internal ribosome entry site-mediated translation. Mutations in this gene have been associated with leukodystrophy with vanishing white matter. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

GeneCards Summary for EIF2B3 Gene

EIF2B3 (Eukaryotic Translation Initiation Factor 2B, Subunit 3 Gamma, 58kDa) is a Protein Coding gene. Diseases associated with EIF2B3 include eif2b3-related childhood ataxia with central nervous system hypomyelination/vanishing white matter and leukoencephalopathy with vanishing white matter. Among its related pathways are Apoptotic Pathways in Synovial Fibroblasts and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include guanyl-nucleotide exchange factor activity and translation factor activity, RNA binding.

Disorders for EIF2B3 Gene

(1) OMIM Diseases for EIF2B3 Gene (606273)


  • Leukodystrophy with vanishing white matter (VWM) [MIM:603896]: A leukodystrophy that occurs mainly in children. Neurological signs include progressive cerebellar ataxia, spasticity, inconstant optic atrophy and relatively preserved mental abilities. The disease is chronic-progressive with, in most individuals, additional episodes of rapid deterioration following febrile infections or minor head trauma. While childhood onset is the most common form of the disorder, some severe forms are apparent at birth. A severe, early-onset form seen among the Cree and Chippewayan populations of Quebec and Manitoba is called Cree leukoencephalopathy. Milder forms may not become evident until adolescence or adulthood. Some females with milder forms of the disease who survive to adolescence exhibit ovarian dysfunction. This variant of the disorder is called ovarioleukodystrophy. {ECO:0000269 PubMed:11835386, ECO:0000269 PubMed:19158808, ECO:0000269 PubMed:21484434}. Note=The disease is caused by mutations affecting the gene represented in this entry.
