Seven of these genes were associated with poor prognosis in ccRCC when highly expressed, namely MTCP1 (p = 0.002), EIF4EBP1 (p < 0.0001), FN1 (p = 0.024), COL1A1 (p = 0.042), EFNA3 (p = 0.00046), COL6A2 (p < 0.0001), and IL2RG (p = 0.047) shown in Figure 5. Here, COL1A1 is linked to nonpapillary renal cell carcinoma.
