Labcorp Genetics (formerly Invitae), Labcorp RCV002039227 SCV002109748 uncertain significance Charcot-Marie-Tooth disease dominant intermediate B 2020-11-21 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with DNM2-related conditions. This sequence change replaces lysine with arginine at codon 257 of the DNM2 protein (p.Lys257Arg). The lysine residue is highly conserved and there is a small physicochemical difference between lysine and arginine. This variant is not present in population databases (ExAC no frequency). 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 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.
