RCV001342527 | SCV001536462 | uncertain significance | Charcot-Marie-Tooth disease type 2 | 2021-08-11 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine with phenylalanine at codon 524 of the MFN2 protein (p.Leu524Phe). The leucine residue is highly conserved and there is a small physicochemical difference between leucine and phenylalanine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MFN2-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt 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. |
