RCV002049102 | SCV002312439 | uncertain significance | Congenital myopathy 4B, autosomal recessive; Congenital myopathy with fiber type disproportion | 2021-10-10 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine with glutamic acid at codon 30 of the TPM3 protein (p.Gln30Glu). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and glutamic acid. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with TPM3-related conditions. 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. 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. |
