Genes affected

GZMH (HGNC:4710): (granzyme H) This gene encodes a member of the peptidase S1 family of serine proteases. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate a chymotrypsin-like protease. This protein is reported to be constitutively expressed in the NK (natural killer) cells of the immune system and may play a role in the cytotoxic arm of the innate immune response by inducing target cell death and by directly cleaving substrates in pathogen-infected cells. This gene is present in a gene cluster with another member of the granzyme subfamily on chromosome 14. [provided by RefSeq, Nov 2015]

Collection Method: clinical testing

The c.555G>T (p.E185D) alteration is located in exon 4 (coding exon 4) of the GZMH gene. This alteration results from a G to T substitution at nucleotide position 555, causing the glutamic acid (E) at amino acid position 185 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
