Invitae RCV000654047 SCV000775937 uncertain significance Charcot-Marie-Tooth disease type 4 2017-11-10 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with alanine at codon 1353 of the PRX protein (p.Glu1353Ala). The glutamic acid residue is weakly conserved and there is a moderate physicochemical difference between glutamic acid and alanine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with PRX-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: "Tolerated"; PolyPhen-2: "Possibly 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.
