Several genes that are known to be important in ACC tumors are highlighted with black dots at right, including (from top to bottom) EN1, GABRP, MYB, MYBL1 and NFIB, all of which are expressed more highly in the ACC tumors than in the normal salivary gland or acinic cell carcinoma samples (at left). This evidence concerns the gene MYB and adrenal cortex carcinoma.
