Genes affected

KLK14 (HGNC:6362): (kallikrein related peptidase 14) This gene encodes a member of the kallikrein subfamily of serine proteases that have diverse physiological functions such as regulation of blood pressure and desquamation. The altered expression of this gene is implicated in the progression of different cancers including breast and prostate tumors. The encoded protein is a precursor that is proteolytically processed to generate the functional enzyme. This gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2015]

The c.344C>T (p.T115M) alteration is located in exon 5 (coding exon 4) of the KLK14 gene. This alteration results from a C to T substitution at nucleotide position 344, causing the threonine (T) at amino acid position 115 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
