We observed that the tumor types with highly significant KDM7A-DT gain and amplification were highly aggressive, including hepatocellular carcinoma (p = 8.8E-13), pilocytic astrocytoma (p = 3.43E-10), melanoma (p = 5.21E-10), prostate adenocarcinoma (p = 5.16E-08), medulloblastoma (p = 4.20E-07), and colorectal carcinoma (p = 6.14E-04). Here, KDM7A is linked to colorectal carcinoma.
