International audience. Aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia are the main cause of primary aldosteronism (PA), the most frequent form of secondary hypertension. Mutations in ion channels and ATPases have been identified in APA and inherited forms of PA, highlighting the central role of calcium signaling in PA development. Different somatic mutations are also found in aldosterone-producing cell clusters in adrenal glands from healthy individuals and from patients with unilateral and bilateral PA, suggesting additional pathogenic mechanisms. Recent mouse models have also contributed to a better understanding of PA. Application of genetic screening in familial PA, development of surrogate biomarkers for somatic mutations in APA, and use of targeted treatment directed at mutated proteins may allow improved management of patients.
