WDR72 and nonpapillary renal cell carcinoma: Kaplan-Meier plots showed that in the promoter regions of WDR72, hypomethylation of two CpG sites, cg18613421 and cg24866923, located in the 5’UTR region predicted favourable OS of ccRCC (Supplementary Figure 6E, 6F) and no statistical significance was found in other CpG sites of promoter region (Supplementary Figure 6B–6D).
