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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2023The c.335A>G (p.Y112C) alteration is located in exon 4 (coding exon 3) of the SERPINB9 gene. This alteration results from a A to G substitution at nucleotide position 335, causing the tyrosine (Y) at amino acid position 112 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
