Congenital myopathy with internal nuclei and atypical cores Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 28, 2023This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 35 of the CCDC78 protein (p.Gly35Asp). This variant is present in population databases (no rsID available, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with CCDC78-related conditions. ClinVar contains an entry for this variant (Variation ID: 447005). 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 CCDC78 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
