Genes affected

TMPRSS3 (HGNC:11877): (transmembrane serine protease 3) This gene encodes a protein that belongs to the serine protease family. The encoded protein contains a serine protease domain, a transmembrane domain, an LDL receptor-like domain, and a scavenger receptor cysteine-rich domain. Serine proteases are known to be involved in a variety of biological processes, whose malfunction often leads to human diseases and disorders. This gene was identified by its association with both congenital and childhood onset autosomal recessive deafness. This gene is expressed in fetal cochlea and many other tissues, and is thought to be involved in the development and maintenance of the inner ear or the contents of the perilymph and endolymph. This gene was also identified as a tumor-associated gene that is overexpressed in ovarian tumors. Alternatively spliced transcript variants have been described. [provided by RefSeq, Jan 2012]

Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Jan 04, 2019	The p.Gly94Arg variant in TMPRSS3 has been reported in at least 2 individuals wi th hearing loss (Miyagawa 2013, LMM data). It has also been identified in 0.03% (42/129164) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org) and has been reported in ClinVar (Variation ID: 440339). Computational predicti on tools and conservation analysis suggest that the p.Gly94Arg variant may impac t the protein, though this information is not predictive enough to determine pat hogenicity. In summary, the clinical significance of the p.Gly94Arg variant is u ncertain. ACMG/AMP criteria applied: PM2_Supporting, PP3. -

Uncertain significance, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 94 of the TMPRSS3 protein (p.Gly94Arg). This variant is present in population databases (rs143762350, gnomAD 0.03%). This missense change has been observed in individual(s) with hearing loss (PMID: 23967202, 25770132). ClinVar contains an entry for this variant (Variation ID: 440339). 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. 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. -
