Genes affected

PRSS57 (HGNC:31397): (serine protease 57) This gene encodes an arginine-specific serine protease and member of the peptidase S1 family of proteins. The encoded protein may undergo proteolytic activation before storage in azurophil granules, in neutrophil cells of the immune system. Following neutrophil activation, the protease is released into the pericellular environment, where it may play a role in defense against microbial pathogens. [provided by RefSeq, Jul 2016]

Collection Method: clinical testing

The c.757G>A (p.A253T) alteration is located in exon 5 (coding exon 5) of the PRSS57 gene. This alteration results from a G to A substitution at nucleotide position 757, causing the alanine (A) at amino acid position 253 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
