Genes affected

KLK9 (HGNC:6370): (kallikrein related peptidase 9) The protein encoded by this gene is a kallikrein-related serine protease. This gene is activated by steroid hormones in a human breast cancer cell line, making it a good marker for cancer detection. The encoded protein is found primarily in the cytoplasm.[provided by RefSeq, Oct 2010]

The c.568G>A (p.A190T) alteration is located in exon 4 (coding exon 4) of the KLK9 gene. This alteration results from a G to A substitution at nucleotide position 568, causing the alanine (A) at amino acid position 190 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
