Genes affected

KLK12 (HGNC:6360): (kallikrein related peptidase 12) 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. Alternate splicing of this gene results in three transcript variants encoding different isoforms.

Ambry Genetics

Nov 02, 2023

The c.179C>T (p.A60V) alteration is located in exon 3 (coding exon 2) of the KLK12 gene. This alteration results from a C to T substitution at nucleotide position 179, causing the alanine (A) at amino acid position 60 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
