Invitae RCV000703288 SCV000832184 uncertain significance Charcot-Marie-Tooth disease type 4 2018-06-20 criteria provided, single submitter clinical testing This sequence change replaces serine with proline at codon 814 of the PRX protein (p.Ser814Pro). The serine residue is moderately conserved and there is a moderate physicochemical difference between serine and proline. This variant is present in population databases (rs201809431, ExAC 0.02%). 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0". The proline amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
