Genomic studies indicate that mutations in defined driver genes, including zinc and ring finger 3 (ZNRF3), telomerase reverse transcriptase (TERT), protein kinase cAMP-dependent type I regulatory subunit alpha (PRKAR1A), ribosomal protein L22 (RPL22), telomeric repeat binding factor 2 (TERF2), cyclin E1 (CCNE1), and neurofibromin 1 (NF1), may have a major role in the etiology of ACC [2], and that ACC has a moderate overall mutation burden compared with other tumor types [3]. Here, RPL22 is linked to adrenal cortex carcinoma.
