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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.245C>T (p.T82M) alteration is located in exon 2 (coding exon 2) of the TMPRSS9 gene. This alteration results from a C to T substitution at nucleotide position 245, causing the threonine (T) at amino acid position 82 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
