Invitae | RCV001979976 | SCV002227348 | uncertain significance | Amyotrophic lateral sclerosis type 21 | 2021-08-19 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine with valine at codon 666 of the MATR3 protein (p.Ala666Val). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and valine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in individual(s) with clinical features of MATR3-related conditions (Invitae). 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. |
