Labcorp Genetics (formerly Invitae), Labcorp RCV001221817 SCV001393880 uncertain significance Congenital myopathy 4B, autosomal recessive; Congenital myopathy with fiber type disproportion 2023-07-07 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 42 of the TPM3 protein (p.Asp42Asn). This variant has not been reported in the literature in individuals affected with TPM3-related conditions. 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. 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 TPM3 protein function. ClinVar contains an entry for this variant (Variation ID: 950167).
