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 Asp400Glu varia nt in TMPRSS3 has not been reported in the literature nor previously identified by our laboratory. This residue is conserved across species and computational an alyses (PolyPhen, SIFT, AlignGVGD) suggest that the Asp400Glu variant may impact the protein. However, this information is not predictive enough to assume patho genicity. In summary, the clinical significance of this variant cannot be determ ined at this time. -
