To prioritize genes, a literature review of the candidate markers was conducted to identify genes associated with cell proliferation, tumor growth, invasion, and prognosis, and 14 markers were selected for additional verification (KDF1, EPPK1, QSOX2, DHTKD1, MAP1B, CENPJ, E2F3, TMED2, TM9SF4, COL3A1, CCDC116, TAL1, CDK1, and VPS13B). The gene discussed is CPAP; the disease is neoplasm.
