Invitae RCV000638174 SCV000759660 uncertain significance Charcot-Marie-Tooth disease, type I 2017-12-14 criteria provided, single submitter clinical testing This sequence change replaces valine with phenylalanine at codon 58 of the MPZ protein (p.Val58Phe). The valine residue is moderately conserved and there is a small physicochemical difference between valine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in an individual affected with Charcot-Marie-Tooth disease, type 1 (PMID: 9452099). 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: "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.
