Genes affected

CTSG (HGNC:2532): (cathepsin G) The protein encoded by this gene, a member of the peptidase S1 protein family, is found in azurophil granules of neutrophilic polymorphonuclear leukocytes. The encoded protease has a specificity similar to that of chymotrypsin C, and may participate in the killing and digestion of engulfed pathogens, and in connective tissue remodeling at sites of inflammation. In addition, the encoded protein is antimicrobial, with bacteriocidal activity against S. aureus and N. gonorrhoeae. Transcript variants utilizing alternative polyadenylation signals exist for this gene. [provided by RefSeq, Sep 2014]

Ambry Genetics

Jun 24, 2022

The c.58G>A (p.E20K) alteration is located in exon 2 (coding exon 2) of the CTSG gene. This alteration results from a G to A substitution at nucleotide position 58, causing the glutamic acid (E) at amino acid position 20 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
