Familial hyperaldosteronism (FH) is an uncommon subset of primary aldosteronism. There are three forms of FH:
●FH type I or glucocorticoid-remediable aldosteronism (GRA) due to a CYP11B1/CYP11B2 chimeric gene
●FH type II, which has been localized to chromosome 7p22, but exact location of mutation(s) is unknown to date
●FH type III caused by germline mutations in the potassium channel subunit KCNJ5
The three forms of FH will be reviewed here. Primary aldosteronism is discussed separately. (See "Diagnosis of primary aldosteronism" and "Pathophysiology and clinical features of primary aldosteronism" and "Treatment of primary aldosteronism".)To continue reading this article, you must log in with your personal, hospital, or group practice subscription.
