Leukoencephalopathy with vanishing white matter is an autosomal recessive neurological disease. The cause of the disease are mutations in any of the 5 genes encoding subunits of the translation initiation factor eIF2B: EIF2B1, EIF2B2, EIF2B3, EIF2B4, or EIF2B5. The disease belongs to a family of conditions called the Leukodystrophies.

Rap guanine nucleotide exchange factor 5 is a protein that in humans is encoded by the RAPGEF5 gene.

eIF2B is a protein complex found in eukaryotes. It is the guanine nucleotide exchange factor for the eukaryotic initiation factor 2 and therefore converts the inactive eIF2-GDP to the active eIF2-GTP. This activation is hindered by phosphorylation of the alpha subunit of eIF2, which leads to a stable eIF2α-P-GDP-eIF2B complex and therefore inhibits translation initiation.

Eukaryotic Initiation Factor 2 (eIF2) is an eukaryotic initiation factor. It is required for most forms of eukaryotic translation initiation. eIF2 mediates the binding of tRNAiMet to the ribosome in a GTP-dependent manner. eIF2 is a heterotrimer consisting of an alpha, a beta, and a gamma subunit.

<span class="mw-page-title-main">EIF-W2 protein domain</span>

In molecular biology, the protein domain eIF4-gamma/eIF5/eIF2-epsilon is a family of evolutionarily related proteins. This domain is found at the C-terminus of several translation Initiation factors. It was first detected at the very C-termini of the yeast protein GCD6, eIF-2B epsilon, and two other eukaryotic translation initiation factors, eIF-4 gamma and eIF-5 and it may be involved in the interaction of eIF-2B, eIF-4 gamma, and eIF-5 with eIF-2.
