RCV001097108 | SCV001253362 | uncertain significance | Vanishing white matter disease | 2018-01-13 | criteria provided, single submitter | clinical testing | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. |

RCV001288965 | SCV003288161 | uncertain significance | not provided | 2022-07-07 | 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 155 of the EIF2B3 protein (p.Arg155His). This variant is present in population databases (rs147773599, gnomAD 0.08%). This missense change has been observed in individual(s) with clinical features of leukoencephalopathy with vanishing white matter although a second variant was not observed (PMID: 31692161). ClinVar contains an entry for this variant (Variation ID: 874280). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
| Ambry Genetics | RCV004619515 | SCV005119472 | uncertain significance | Inborn genetic diseases | 2024-03-27 | criteria provided, single submitter | clinical testing | The c.464G>A (p.R155H) alteration is located in exon 5 (coding exon 4) of the EIF2B3 gene. This alteration results from a G to A substitution at nucleotide position 464, causing the arginine (R) at amino acid position 155 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
