The evidence is unclear, but it is possible that certain circumstances may aggravate the condition and accelerate neurological decline, including head trauma (children may benefit from wearing helmets), contact sports, and stressful situations (including high body temperature, and prophylactic measures and rapid treatment related to infections may be beneficial)

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the EIF2B2 gene is commonly pathogenic or not. These statistics are base on transcript: NM_000014239.4. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

Function: FUNCTION: Catalyzes the exchange of eukaryotic initiation factor 2-bound GDP for GTP.;
Disease: DISEASE: 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.;
