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]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Asp100His variant in TMPRSS3 has been reported by our laboratory in 1 Cauc asian individual with hearing loss; however, a variant affecting the remaining c opy of TMPRSS3 was not identified in this individual (LMM unpublished data). It has also been identified in 1/11568 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs397517374). Computatio nal prediction tools and conservation analysis suggest that the p.Asp100His vari ant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the p.Asp10 0His variant is uncertain. -

This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 100 of the TMPRSS3 protein (p.Asp100His). This variant is present in population databases (rs397517374, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with TMPRSS3-related conditions. ClinVar contains an entry for this variant (Variation ID: 46110). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on 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. -
