Invitae | RCV002236010 | SCV002510448 | uncertain significance | Charcot-Marie-Tooth disease type 2 | 2021-10-23 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). This sequence change replaces isoleucine with threonine at codon 463 of the AARS protein (p.Ile463Thr). The isoleucine residue is moderately conserved and there is a moderate physicochemical difference between isoleucine and threonine. This missense change has been observed in individual(s) with clinical features of Charcot-Marie-Tooth disease (PMID: 32376792). 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. 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: "Benign"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 810833). |
