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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.985G>A (p.A329T) alteration is located in exon 7 (coding exon 6) of the SERPINB9 gene. This alteration results from a G to A substitution at nucleotide position 985, causing the alanine (A) at amino acid position 329 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
