RCV003069647 | SCV003471768 | uncertain significance | Methylcobalamin deficiency type cblG | 2022-03-31 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 205 of the MTR protein (p.Ala205Val). This variant is present in population databases (rs763284188, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with MTR-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. |
