Invitae RCV001218473 SCV001390355 uncertain significance Congenital myopathy 4B, autosomal recessive; Congenital myopathy with fiber type disproportion 2022-10-17 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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: 947402). This variant has not been reported in the literature in individuals affected with TPM3-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 272 of the TPM3 protein (p.Ser272Arg).
