Labcorp Genetics (formerly Invitae), Labcorp RCV002730422 SCV003018769 likely pathogenic not provided 2022-04-22 criteria provided, single submitter clinical testing In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a 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 expected to disrupt TMPRSS3 protein function. This missense change has been observed in individual(s) with autosomal recessive deafness (PMID: 32860223; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tryptophan, which is neutral and slightly polar, with serine, which is neutral and polar, at codon 343 of the TMPRSS3 protein (p.Trp343Ser).
