Invitae RCV001069302 SCV001234461 uncertain significance Charcot-Marie-Tooth disease, dominant intermediate B 2019-11-28 criteria provided, single submitter clinical testing This sequence change replaces alanine with valine at codon 732 of the DNM2 protein (p.Ala732Val). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and valine. This variant is present in population databases (rs375577182, ExAC 0.02%). This variant has not been reported in the literature in individuals with DNM2-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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.
