Invitae RCV000794914 SCV000934349 uncertain significance Neuronopathy, distal hereditary motor, autosomal recessive 4; Charcot-Marie-Tooth disease recessive intermediate C 2021-09-01 criteria provided, single submitter clinical testing This sequence change replaces arginine with glutamine at codon 20 of the PLEKHG5 protein (p.Arg20Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with PLEKHG5-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: "Tolerated"; 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. 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.
