Invitae RCV000527378 SCV000658027 uncertain significance Charcot-Marie-Tooth disease type 4 2018-10-10 criteria provided, single submitter clinical testing This sequence change replaces valine with isoleucine at codon 1403 of the PRX protein (p.Val1403Ile). The valine residue is weakly conserved and there is a small physicochemical difference between valine and isoleucine. This variant is present in population databases (rs139051512, ExAC 0.009%) but has not been reported in the literature in individuals with a PRX-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
