The mechanism thought to underlie hyperaldosteronism in patients with KCNJ5 mutations that cause Kir3.4 to lose its potassium selectivity. The mutated channels allow sodium entry, which triggers depolarization.

Abbreviations: CYP11B2, aldosterone synthase; TASK, TWIK-related acid sensitive K channels; Kir3.4, inwardly rectifying potassium channel Kir3.4; AT1R, type 1 angiotensin II receptor; Cav 3.x, low-voltage activated calcium channels; Cav 1.x, high-voltage activated calcium channels; MC2R, ACTH receptor; ACTH, adrenocorticotropic hormone.
