Figure 1C1–C7 and Figure 1D1–D7 revealed OS and RFS of the 7 pseudogenes, respectively. To discover the most potential functional pseudogenes in RCC, we performed survival analysis (OS and RFS) of the 7 pseudogenes in chRCC and pRCC. As listed in Table 1 and Figure 2, only chRCC and pRCC patients with higher expression of DUXAP8 and DUXAP9 predicted poorer prognosis. Here, DUXAP9 is linked to renal cell carcinoma.
