In glucocorticoid-remediable aldosteronism (GRA), the RAS is suppressed, and aldosterone is regulated by corticotropin because of the chimeric gene fusion of a corticotropin-sensitive promoter with the coding regions of the aldosterone synthetase gene (which normally does not have such a promoter). Thus, ambient corticotropin levels pathologically overstimulate aldosterone synthesis inappropriately. [6]
