Labcorp Genetics (formerly Invitae), Labcorp RCV000701835 SCV000830654 pathogenic Charcot-Marie-Tooth disease, type I 2022-05-12 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Tyr82 amino acid residue in MPZ. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 7505151, 11545686, 11835375, 12402337, 26310628). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 549681). This missense change has been observed in individual(s) with Charcot-Marie-Tooth (CMT) disease type 1 and Déjérine-Sottas syndrome (PMID: 7505151, 9633821, 11545686, 11835375, 12402337, 26310628). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 82 of the MPZ protein (p.Tyr82Cys).
