Invitae RCV000168067 SCV000218721 pathogenic Charcot-Marie-Tooth disease, type I 2023-12-19 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 61 of the MPZ protein (p.Asp61Gly). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with clinical features of Charcot-Marie-Tooth disease (PMID: 10764043; Invitae). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 188168). 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 not expected to disrupt MPZ protein function with a negative predictive value of 80%. This variant disrupts the p.Asp61 amino acid residue in MPZ. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 11484669, 22451207, 23290023). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic.
