Genes affected
KLK13 (HGNC:6361): (kallikrein related peptidase 13) 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. Expression of this gene is regulated by steroid hormones and may be useful as a marker for breast cancer. [provided by RefSeq, Jan 2017]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2024The c.731G>A (p.R244Q) alteration is located in exon 5 (coding exon 5) of the KLK13 gene. This alteration results from a G to A substitution at nucleotide position 731, causing the arginine (R) at amino acid position 244 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
