Invitae | RCV000550833 | SCV000655839 | uncertain significance | Charcot-Marie-Tooth disease, axonal, type 2z | 2017-07-26 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with tryptophan at codon 264 of the MORC2 protein (p.Arg264Trp). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is present in population databases (rs558057376, ExAC 0.01%). This variant has not been reported in the literature in individuals with MORC2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; 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. |
