Genes affected

TMPRSS9 (HGNC:30079): (transmembrane serine protease 9) The protein encoded by this gene is a membrane-bound type II serine polyprotease that is cleaved to release three different proteases. Two of the proteases are active and can be inhibited by serine protease inhibitors, and one is thought to be catalytically inactive. This gene enhances the invasive capability of pancreatic cancer cells and may be involved in cancer progression. [provided by RefSeq, Jul 2016]

Collection Method: clinical testing

The c.290C>T (p.P97L) alteration is located in exon 3 (coding exon 3) of the TMPRSS9 gene. This alteration results from a C to T substitution at nucleotide position 290, causing the proline (P) at amino acid position 97 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
