Invitae | RCV000461805 | SCV000552945 | uncertain significance | Charcot-Marie-Tooth disease, type I | 2016-12-25 | criteria provided, single submitter | clinical testing | 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 disruptive, but these predictions have not been confirmed by published functional studies. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with an MPZ-related disease. This sequence change replaces tryptophan with arginine at codon 66 of the MPZ protein (p.Trp66Arg). The tryptophan residue is highly conserved and there is a moderate physicochemical difference between tryptophan and arginine. |
