The expression of GRAMD1C, NFKBIA, and ACSS2 was significantly higher in normal tissues than in tumour tissues (P < 0.001, P = 0.0096, and P < 0.001, respectively), which indicated that CD24 and INHBA were risk genes and that GRAMD1C, NFKBIA, and ACSS2 were protective genes (Fig. S2). This evidence concerns the gene CD24 and neoplasm.
