Labcorp Genetics (formerly Invitae), Labcorp RCV005107087 SCV005733777 pathogenic Charcot-Marie-Tooth disease axonal type 2O 2024-05-17 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 3310 of the DYNC1H1 protein (p.Met3310Val). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with clinical features of Lennox-Gastout syndrome (Invitae). In at least one individual the variant was observed to be de novo. 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 DYNC1H1 protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic.
