We next explored KRAS expression in different cancers compared to normal tissue, and discovered that it is highly expressed in eight cancers (BRCA, CHOL, ESCA, HNSC, LIHC, LUAD, LUSC, and STAD) while it has low expression in four cancers (COAD, KIRC, READ and THCA). The gene discussed is KRAS; the disease is cancer.
