According to the correlation between the predictive expression of 7 metastasis-related lncRNAs (Figure 8A) and the OS of ccRCC patients from TCGA database (Supplementary File S6), the expression of SSR3-6, WISP1-2, CYP4F22-3 and UBAC2-6 were identified in carcinoma and adjacent tissues of ccRCC patients (normal=9, tumor=9) (Figure 8B). The gene discussed is CYP4F22; the disease is neoplasm.
