Labcorp Genetics (formerly Invitae), Labcorp RCV001930107 SCV002129260 uncertain significance Neuronopathy, distal hereditary motor, autosomal recessive 4; Charcot-Marie-Tooth disease recessive intermediate C 2022-08-21 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 609 of the PLEKHG5 protein (p.Thr609Met). This variant is present in population databases (rs553151077, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of Charcot-Marie-Tooth disease (PMID: 33220101). This variant is also known as c.2057C>T (p.Thr686Met). ClinVar contains an entry for this variant (Variation ID: 1366373). 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"). 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.
