| Invitae | RCV000820512 | SCV000961228 | pathogenic | Charcot-Marie-Tooth disease axonal type 2Z | 2023-03-13 | criteria provided, single submitter | clinical testing | For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Arg132 amino acid residue in MORC2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 31618753, 32693025). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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 MORC2 protein function. ClinVar contains an entry for this variant (Variation ID: 662781). This missense change has been observed in individuals with clinical features of Charcot-Marie-Tooth disease (PMID: 27105897). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 132 of the MORC2 protein (p.Arg132Leu). |
