Genes affected

SERPINB9 (HGNC:8955): (serpin family B member 9) This gene encodes a member of the serine protease inhibitor family which are also known as serpins. The encoded protein belongs to a subfamily of intracellular serpins. This protein inhibits the activity of the effector molecule granzyme B. Overexpression of this protein may prevent cytotoxic T-lymphocytes from eliminating certain tumor cells. A pseudogene of this gene is found on chromosome 6. [provided by RefSeq, Mar 2012]

Ambry Genetics

Feb 06, 2023

The c.965T>C (p.V322A) alteration is located in exon 7 (coding exon 6) of the SERPINB9 gene. This alteration results from a T to C substitution at nucleotide position 965, causing the valine (V) at amino acid position 322 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
