Genes affected

PRSS58 (HGNC:39125): (serine protease 58) This gene encodes a member of the trypsin family of serine proteases. This gene and several related trypsinogen genes are localized to the T cell receptor beta locus on chromosome 7. This gene was previously described as a trypsinogen-like pseudogene, but it is now thought to be a protein-coding gene. [provided by RefSeq, Jul 2008]

The c.496C>T (p.R166C) alteration is located in exon 5 (coding exon 4) of the PRSS58 gene. This alteration results from a C to T substitution at nucleotide position 496, causing the arginine (R) at amino acid position 166 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
