Introduction: Cushing’s disease (CD) is caused by pituitary tumors hypersecreting adrenocorticotropin (ACTH). Until now somatic mutations in the 14-3-3 binding domain of Ubiquitin Specific Peptidase 8 gene (USP8) were the only recurring, driver mutations and were described in about 40% of the 446 CD samples that have been analysed wordwide. We wanted to assess if other driver mutations might be the pathogenetic cause of CD in those tumors without USP8 mu...
