Genes affected

EIF2B5 (HGNC:3261): (eukaryotic translation initiation factor 2B subunit epsilon) 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]

Variant summary: EIF2B5 c.925G>C (p.Val309Leu) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 1.2e-05 in 251458 control chromosomes. c.925G>C has been reported in the literature in individuals affected with Leukoencephalopathy With Vanishing White Matter (example: Huyghe_2012,Fogli_2002). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 22737209, 12499492). ClinVar contains an entry for this variant (Variation ID: 5947). Based on the evidence outlined above, the variant was classified as likely pathogenic. -
