Labcorp Genetics (formerly Invitae), Labcorp RCV001312798 SCV001503269 uncertain significance Congenital myopathy 4B, autosomal recessive; Congenital myopathy with fiber type disproportion 2022-11-15 criteria provided, single submitter clinical testing 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 expected to disrupt TPM3 protein function. ClinVar contains an entry for this variant (Variation ID: 1014108). This missense change has been observed in individual(s) with congenital myopathy (PMID: 35741838). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 237 of the TPM3 protein (p.Glu237Lys). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.
