We further observed that reductions of IQGAP1 mRNA expression at −0.6 SD (standard deviation or z-scores at −0.6), −0.8 SD, and −1 SD significantly stratified ccRCCs into high- and low-risk groups of fatality within the TCGA PanCancer Atlas ccRCC dataset (Figure S1B–D). This evidence concerns the gene IQGAP1 and nonpapillary renal cell carcinoma.
