Neuberg Centre For Genomic Medicine, NCGM RCV003340883 SCV004047691 uncertain significance Leukoencephalopathy with vanishing white matter 1 criteria provided, single submitter clinical testing The c.752A>G (p.Lys251Arg) missense variant in EIF2B1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The p.Lys251Arg variant is novel (not in any individuals) in gnomAD Exomes and 1000 Genomes. The amino acid Lys at position 251 is changed to a Arg changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Lys251Arg in EIF2B1 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Variant of Uncertain Significance (VUS). In the absence of another reportable variant the molecular diagnosis is not confirmed.
