Invitae | RCV000697773 | SCV000826402 | uncertain significance | Charcot-Marie-Tooth disease type 4 | 2019-04-09 | criteria provided, single submitter | clinical testing | This sequence change replaces cysteine with arginine at codon 86 of the PRX protein (p.Cys86Arg). The cysteine residue is highly conserved and there is a large physicochemical difference between cysteine and arginine. This variant is present in population databases (rs765676916, ExAC 0.002%). 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: "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. |
