PTK2 and ovarian carcinoma: The genes exhibiting the highest frequency of copy number variations (CNVs) in the 589 samples of epithelial ovarian cancer (EOC) are depicted in Figure 1D. Notably, the MYC gene, a well-established oncogene, demonstrates the most frequent CNV events (407/589, 69.10%), followed by the PTK2 gene (401/589, 68.08%).
