However, the same comprehensive overall survival analysis was done in UALCAN, and we found that CDKN2A showed a great significance in 14 cancers of which four cancers were associated with high gene expression, including COAD (p = 0.031), LIHC (p = 0.014), MESO (p = 0.0099), and PCPG (p = 0.068) (supplementary Figures 15A-15D) and associated with low gene expression in 10 cancers, including ACC, CESC, LUAD, HNSC, KICH, KIRC, KIRP, TGCT, THYM, and UCES. The gene discussed is CDKN2A; the disease is cancer.
