Introduction: Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH) is a rare disease responsible for variable levels of cortisol excess. Constitutional pathogenic variants of the tumor suppressor gene ARMC5 are its most frequent molecular cause (20% of index cases). Recently, KDM1A has been identified as the causing gene for PBMAH associated with food-dependent Cushing’s syndrome (FDCS), consecutive to the illegitimate expression of the GIP recepto...
