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]

Ambry Genetics

Dec 28, 2022

The c.406T>C (p.C136R) alteration is located in exon 3 (coding exon 3) of the KLK9 gene. This alteration results from a T to C substitution at nucleotide position 406, causing the cysteine (C) at amino acid position 136 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
