Moreover, the high ANG expression cohort showed high CNA frequency, with more deletion in tumor-suppressive genes, including CDKN2A, CDKN2B, MTAP, MLLT3, and PTEN, while with more amplification in oncogenic genes, including EGFR, CDK4, FIP1L1, PDGFRA, CHIC2, PIK3C2B, MDM4, MBD6, and DDIT3 (Figure 3B). The gene discussed is CDK4; the disease is neoplasm.
