Genes affected

KLK2 (HGNC:6363): (kallikrein related peptidase 2) This gene encodes a member of the grandular kallikrein protein family. Kallikreins are a subgroup of serine proteases that are clustered on chromosome 19. Members of this family are involved in a diverse array of biological functions. The protein encoded by this gene is a highly active trypsin-like serine protease that selectively cleaves at arginine residues. This protein is primarily expressed in prostatic tissue and is responsible for cleaving pro-prostate-specific antigen into its enzymatically active form. This gene is highly expressed in prostate tumor cells and may be a prognostic maker for prostate cancer risk. Alternate splicing results in both coding and non-coding transcript variants.

Ambry Genetics

Nov 07, 2024

The c.380C>T (p.S127L) alteration is located in exon 3 (coding exon 3) of the KLK2 gene. This alteration results from a C to T substitution at nucleotide position 380, causing the serine (S) at amino acid position 127 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
