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]

Identified in a patient with sensorineural hearing loss in published literature (PMID: 34515852); In silico analysis is inconclusive as to whether the variant alters gene splicing. In the absence of RNA/functional studies, the actual effect of this sequence change is unknown.; This variant is associated with the following publications: (PMID: 34515852) -

This sequence change falls in intron 7 of the TMPRSS3 gene. It does not directly change the encoded amino acid sequence of the TMPRSS3 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs138768408, gnomAD 0.03%). 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: 46124). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). 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. -

Variant classified as Uncertain Significance - Favor Benign. The c.616+5G>A vari ant in TMPRSS3 has been reported by our laboratory in 1 Caucasian individual wit h hearing loss, who was compound heterozygous for 2 pathogenic variants in USH2A , which likely explained this individual's hearing loss. This variant has been identified in 30/65986 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs138768408). Although it has been seen in the general population, its frequency is not high enough to rule out a p athogenic role. This variant is located in the 5' splice region. Computational t ools do not suggest an impact to splicing. However, this information is not pred ictive enough to rule out pathogenicity. In summary, while the clinical signific ance of the c.616+5G>A variant is uncertain, these data suggest that it is more likely to be benign. -

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -
