    Cushing's syndrome is a critical state of endogenous hypercortisolemia with metabolic, cardiovascular, and musculoskeletal complications that requires surgical or medical treatment

    The cause is a germline inactivating mutation of PRKAR1A (a regulatory unit of PKA) or phosphodiesterase 11A (PDE11A)


    Methods: Fifty-seven patients with CPA underwent adrenalectomy at Seoul National University Hospital


    Results: The incidence of PRKACA L206R mutation was 51% (29/57)

    Analysis of differentially expressed genes (DEGs) between protein kinase camp-activated catalytic subunit alpha (PRKACA) L206R mutant and wild-type cortisol-producing adenomas (CPAs) (A) V volcano plot of DEGs with PRKACA L206R mutation on the x-axis The magnitude of the difference in gene expression between body and wild-type CPAs, and the y-axis is the statistical significance of the difference

    Transcriptome analysis supported that the PRKACA L206R mutation in CPAS resulted in increased hormone activity and limited proliferative capacity
