The results of the CTPAC online tool implied that CDC42 protein was enriched in clear cell renal cell carcinoma (ccRCC, p = 1.7e-08), hepatocellular carcinoma (HCC, p = 1.0e-05), head and neck cancer (HNSC, 5.3e-18), and endometrioid cancer (UCEC, p = 1.5e-09) compared to normal tissues (Figure 2C). The gene discussed is CDC42; the disease is head and neck cancer.
