CDKN1A and neoplasm: We also noticed a number of known oncogenes in the list of CNA-affected genes, including Cdkn1a, Dach1, Erbb4, Klf5, Myc, and Ppp6c. The number of CNA-affected oncogenes and tumor suppressor genes per tumor is shown in Fig. 3C. Furthermore, we found 5556 CNDs from the 8 mouse tumors, with a frequency of 694.5 CNDs per tumor (Fig. 3A).
