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]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 81 of the EIF2B5 protein (p.Glu81Lys). This variant is present in population databases (rs113994047, gnomAD 0.004%). This missense change has been observed in individuals with autosomal recessive leukoencephalopathy with vanishing white matter (PMID: 15054402, 15136673, 18263758, 27665184). ClinVar contains an entry for this variant (Variation ID: 285116). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt EIF2B5 protein function. For these reasons, this variant has been classified as Pathogenic. -
