RCV001070077 | SCV001235287 | pathogenic | not provided | 2024-01-31 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 315 of the EIF2B5 protein (p.Arg315His). This variant is present in population databases (rs113994064, gnomAD 0.007%). This missense change has been observed in individuals with leukoencephalopathy with vanishing white matter (PMID: 11704758, 17646634; Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 5950). 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 not expected to disrupt EIF2B5 protein function with a negative predictive value of 80%. This variant disrupts the p.Arg315 amino acid residue in EIF2B5. Other variant(s) that disrupt this residue have been observed in individuals with EIF2B5-related conditions (PMID: 11704758, 15136673, 21307862), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. |
