  • Title: Glucocorticoid-remediable aldosteronism.
    Author: Halperin F, Dluhy RG.
    Journal: Endocrinol Metab Clin North Am; 2011 Jun; 40(2):333-41, viii. PubMed ID: 21565670.
    Abstract:
    Glucocorticoid-remediable aldosteronism (GRA) is a hereditary form of primary hyperaldosteronism and the most common monogenic cause of hypertension. A chimeric gene duplication leads to ectopic aldosterone synthase activity in the cortisol-producing zona fasciculata of the adrenal cortex, under the regulation of adrenocorticotropin (ACTH). Hypertension typically develops in childhood, and may be refractory to standard therapies. Hypokalemia is uncommon in the absence of treatment with diuretics. The discovery of the genetic basis of the disorder has permitted the development of accurate diagnostic testing. Glucocorticoid suppression of ACTH is the mainstay of treatment; alternative treatments include mineralocorticoid receptor antagonists.
