Similarly, after adjusting for correlation by tumor purity in TIMER, IGFLR1 expression level was significantly correlated with CD33 (partial cor = 0.61, p < 0.001) and CD11b (partial cor = 0.499, p < 0.001) in ccRCC (Figures 5E,G). The gene discussed is CD33; the disease is nonpapillary renal cell carcinoma.
