Labcorp Genetics (formerly Invitae), Labcorp RCV005080404 SCV005714434 uncertain significance Charcot-Marie-Tooth disease type 2 2024-04-09 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with glycine, which is neutral and non-polar, at codon 502 of the LMNA protein (p.Ala502Gly). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with arrhythmogenic cardiomyopathy (Invitae). 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 LMNA protein function with a positive predictive value of 95%. 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.
