Introduction: Adrenal Cushing due to bilateral multiple adrenal tumors known as Primary Pigmented Nodular Adrenocortical Disease (PPNAD) can be observed in the multiple neoplasia syndrome Carney Complex or as an isolated disease. In both situations germline inactivating mutations of PRKAR1A (regulatory subunit R1A of PKA) can be observed. The loss of PKA R1A results in an increased PKA activity. Comparison of the transcriptome of PPNAD and stably transfected H295R adr...
