Genes affected

PLK1 (HGNC:9077): (polo like kinase 1) The Ser/Thr protein kinase encoded by this gene belongs to the CDC5/Polo subfamily. It is highly expressed during mitosis and elevated levels are found in many different types of cancer. Depletion of this protein in cancer cells dramatically inhibited cell proliferation and induced apoptosis; hence, it is a target for cancer therapy. [provided by RefSeq, Sep 2015]

The c.613G>T (p.G205W) alteration is located in exon 3 (coding exon 3) of the PLK1 gene. This alteration results from a G to T substitution at nucleotide position 613, causing the glycine (G) at amino acid position 205 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
