Identification of differentially expressed FRGs in the TCGA database. A The heatmap demonstrates the expression of 19 differentially expressed FRGs in ccRCC samples compared to normal samples. B Volcano plot of 19 differentially expressed FRGs in ccRCC samples compared to normal samples. C The box diagram exhibits the expression patterns, median values, and data ranges of the 19 differentially expressed FRGs. D The correlation network of the 19 differentially expressed FRGs
