Labcorp Genetics (formerly Invitae), Labcorp RCV001361479 SCV001557455 pathogenic Charcot-Marie-Tooth disease axonal type 2O 2023-11-27 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 1679 of the DYNC1H1 protein (p.Arg1679Trp). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This missense change has been observed in individual(s) with clinical features of DYNC1H1-related conditions (PMID: 32376792; Invitae). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 1053168). 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.
