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.521G>A (p.R174H) alteration is located in exon 4 (coding exon 4) of the GZMH gene. This alteration results from a G to A substitution at nucleotide position 521, causing the arginine (R) at amino acid position 174 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
