PA is caused by autonomous overproduction of aldosterone by the adrenal cortex. It is mainly caused by a unilateral aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia. Excess aldosterone leads to arterial hypertension with suppressed renin, frequently associated to hypokalemia. Mutations in genes coding for ion channels and ATPases have been identified in APA, explaining the pathophysiology of increased aldosterone production. Different inherited genetic abnormalities led to the distinction of four forms of familial hyperaldosteronism (type I to IV) and other genetic defects very likely remain to be identified. Somatic mutations are identified in APA, but also in aldosterone-producing cell clusters (APCCs) in normal adrenals, in image-negative unilateral hyperplasia, in transitional lesions and in APCC from adrenals with bilateral adrenal hyperplasia (BAH). Whether these structures are precursors of APA or whether somatic mutations occur in a proliferative adrenal cortex, is still a matter of debate. This review will summarize our knowledge on the molecular mechanisms responsible for PA and the recent discovery of new genes related to early-onset and familial forms of the disease. We will also address new issues concerning genomic and proteomic changes in adrenals with APA and discuss adrenal pathophysiology in relation to aldosterone-producing structures in the adrenal cortex.<\/jats:p>","DOI":"10.1530\/joe-19-0193","type":"journal-article","created":{"date-parts":[[2019,7,3]],"date-time":"2019-07-03T07:07:23Z","timestamp":1562137643000},"page":"R67-R79","update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-5","source":"Crossref","is-referenced-by-count":6,"title":["Molecular mechanisms in primary aldosteronism"],"prefix":"10.1530","volume":"242","author":[{"given":"Kelly","family":"De Sousa","sequence":"first","affiliation":[{"name":"1INSERM, UMRS_970, Paris Cardiovascular Research Center, Paris, France"},{"name":"2Universit\u00e9 Paris Descartes, Sorbonne Paris Cit\u00e9, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alaa B","family":"Abdellatif","sequence":"additional","affiliation":[{"name":"1INSERM, UMRS_970, Paris Cardiovascular Research Center, Paris, France"},{"name":"2Universit\u00e9 Paris Descartes, Sorbonne Paris Cit\u00e9, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rami M","family":"El Zein","sequence":"additional","affiliation":[{"name":"1INSERM, UMRS_970, Paris Cardiovascular Research Center, Paris, France"},{"name":"2Universit\u00e9 Paris Descartes, Sorbonne Paris Cit\u00e9, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria-Christina","family":"Zennaro","sequence":"additional","affiliation":[{"name":"1INSERM, UMRS_970, Paris Cardiovascular Research Center, Paris, France"},{"name":"2Universit\u00e9 Paris Descartes, Sorbonne Paris Cit\u00e9, Paris, France"},{"name":"3Assistance Publique-H\u00f4pitaux de Paris, H\u00f4pital Europ\u00e9en Georges Pompidou, Service de G\u00e9n\u00e9tique, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","container-title":["Journal of Endocrinology"],"original-title":[],"link":[{"URL":"https:\/\/joe.bioscientifica.com\/view\/journals\/joe\/242\/3\/JOE-19-0193.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/joe.bioscientifica.com\/downloadpdf\/journals\/joe\/242\/3\/JOE-19-0193.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,20]],"date-time":"2026-07-20T13:56:48Z","timestamp":1784555808000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.bioscientifica.com\/joe\/article\/242\/3\/R67-R79\/5142"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,9]]},"references-count":0,"journal-issue":{"issue":"3"},"URL":"https:\/\/doi.org\/10.1530\/joe-19-0193","relation":{},"ISSN":["0022-0795","1479-6805"],"issn-type":[{"value":"0022-0795","type":"print"},{"value":"1479-6805","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,9]]}}}
