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]

Variant classified as Uncertain Significance - Favor Benign. The c.783-13C>A var iant in TMPRSS3 has not been previously reported in individuals with hearing los s and was absent from large population studies. This variant has been identifie d in 2/60512 European chromosomes by the Exome Aggregation Consortium (ExAC, htt p://exac.broadinstitute.org; dbSNP rs140443203). Although this variant 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 3' splice region but not in the i nvariant positions in the splice site consensus sequence and computational tools do not suggest an impact to splicing. However, this information is not predicti ve enough to rule out pathogenicity. In summary, while the clinical significance of the c.783-13C>A variant is uncertain, these data suggest that it is more lik ely to be benign. -
