Among them, 10 mRNAs (APOE, ZNF808, TMEM65, EEF2, ELMSAN1, CLN8, 8MP8A, DIP2C, MSR1, and GNB4) were associated with two clinical features, and four mRNAs (IL21R, FCGR3A, CXCL11, and CCR5) had connections with three clinical features, not to mention the star gene, ADAMDEC1, which had an association with the tumor pathological stage, TNM staging system, tumor metastasis, and patients' outcome. The gene discussed is APOE; the disease is neoplasm.
