In molecular subtype, CLCN4 expression was correlated with ACC (P = 4.3E-04), BRCA (P = 3.13E-89), COAD (P = 7.22E-03), ESCA (P = 2.88E-15), HNSC (P = 1.52E-11), KIRP (P = 3.59E-06), LGG (P = 3.16E-05), LUSC (P = 2.38E-06), OV (P = 1.7E-08), PCPG (P = 1.15E-06), PRAD (P = 6.71E-03), SKCM (P = 1.8E-02), STAD (P = 2.27E-07), and UCEC (P = 2E-28) (Figure 5). This evidence concerns the gene CLCN4 and adrenal cortex carcinoma.
