Genes affected

KLK15 (HGNC:20453): (kallikrein related peptidase 15) Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers. This gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. In prostate cancer, this gene has increased expression, which indicates its possible use as a diagnostic or prognostic marker for prostate cancer. The gene contains multiple polyadenylation sites and alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Jul 2008]

The c.188G>A (p.C63Y) alteration is located in exon 2 (coding exon 2) of the KLK15 gene. This alteration results from a G to A substitution at nucleotide position 188, causing the cysteine (C) at amino acid position 63 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
