Invitae RCV000697382 SCV000825990 uncertain significance Charcot-Marie-Tooth disease, axonal, type 2R 2019-09-29 criteria provided, single submitter clinical testing This sequence change replaces arginine with glutamine at codon 423 of the TRIM2 protein (p.Arg423Gln). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs777541972, ExAC 0.002%). This variant has not been reported in the literature in individuals with TRIM2-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Benign"; 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.
