Genes affected

KLK5 (HGNC:6366): (kallikrein related peptidase 5) 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. Its expression is up-regulated by estrogens and progestins. The encoded protein is secreted and may be involved in desquamation in the epidermis. Alternative splicing results in multiple transcript variants encoding the same protein.

Nov 15, 2024

The c.152G>A (p.G51E) alteration is located in exon 3 (coding exon 2) of the KLK5 gene. This alteration results from a G to A substitution at nucleotide position 152, causing the glycine (G) at amino acid position 51 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
