Genes affected

GZMB (HGNC:4709): (granzyme B) This gene encodes a member of the granzyme subfamily of proteins, part of the peptidase S1 family of serine proteases. The encoded preproprotein is secreted by natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) and proteolytically processed to generate the active protease, which induces target cell apoptosis. This protein also processes cytokines and degrades extracellular matrix proteins, and these roles are implicated in chronic inflammation and wound healing. Expression of this gene may be elevated in human patients with cardiac fibrosis. [provided by RefSeq, Sep 2016]

Ambry Genetics

May 20, 2024

The c.400G>T (p.A134S) alteration is located in exon 4 (coding exon 4) of the GZMB gene. This alteration results from a G to T substitution at nucleotide position 400, causing the alanine (A) at amino acid position 134 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
