Labcorp Genetics (formerly Invitae), Labcorp RCV003034645 SCV003328385 uncertain significance Charcot-Marie-Tooth disease type 2 2024-11-05 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with asparagine, which is neutral and polar, at codon 355 of the MFN2 protein (p.Lys355Asn). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MFN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 2112586). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on MFN2 protein function. 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.
