RCV001959748 | SCV002216894 | uncertain significance | Methylcobalamin deficiency type cblG | 2023-08-17 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 495 of the MTR protein (p.Met495Val). This variant is present in population databases (rs775291294, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with MTR-related conditions. ClinVar contains an entry for this variant (Variation ID: 1431942). 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 MTR protein function. 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 | RCV002562040 | SCV003749030 | likely benign | Inborn genetic diseases | 2021-07-14 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |
