Summaries for EIF2B2 Gene

Entrez Gene Summary for EIF2B2 Gene

  • This gene encodes the beta subunit of eukaryotic initiation factor-2B (EIF2B). EIF2B is involved in protein synthesis and exchanges GDP and GTP for its activation and deactivation. [provided by RefSeq, Aug 2011]

GeneCards Summary for EIF2B2 Gene

EIF2B2 (Eukaryotic Translation Initiation Factor 2B, Subunit 2 Beta, 39kDa) is a Protein Coding gene. Diseases associated with EIF2B2 include eif2b2-related childhood ataxia with central nervous system hypomyelination/vanishing white matter and late infantile cach syndrome. Among its related pathways are Apoptotic Pathways in Synovial Fibroblasts and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include GTP binding and translation initiation factor activity.

Disorders for EIF2B2 Gene

(1) OMIM Diseases for EIF2B2 Gene (606454)


  • 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:11704758, ECO:0000269 PubMed:12707859, ECO:0000269 PubMed:15776425, ECO:0000269 PubMed:21484434, ECO:0000269 PubMed:22285377, ECO:0000269 PubMed:22729508}. Note=The disease is caused by mutations affecting the gene represented in this entry.
