We found that IRAK1 expression was associated with a poorer overall survival (OS) in ACC (p = 0.015, HR (high) = 2.6), BRCA (p = 0.029, HR (high) = 1.4), HNSC (p = 0.037, HR (high) = 1.3), KICH (p = 0.024, HR (high) = 5.1), LGG (p < 0.01, HR (high) = 2), LIHC (p = 0.0042, HR (high) = 1.7), and UVM (p = 0.0072, HR (high) = 3.4) (Figure 2). This evidence concerns the gene IRAK1 and adrenal cortex carcinoma.
