Invitae RCV001307835 SCV001497261 uncertain significance Charcot-Marie-Tooth disease axonal type 2Z 2021-05-30 criteria provided, single submitter clinical testing 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: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals with MORC2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces alanine with glycine at codon 433 of the MORC2 protein (p.Ala433Gly). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and glycine.
