RCV002013825 | SCV002299277 | uncertain significance | Congenital myopathy 4B, autosomal recessive; Congenital myopathy with fiber type disproportion | 2022-07-06 | criteria provided, single submitter | clinical testing | 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: 1508214). This variant is present in population databases (no rsID available, gnomAD 0.006%). This sequence change replaces glutamic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 29 of the TPM3 protein (p.Glu29Ala). |
