While germline mutations in KCNJ5 and CACNA1D were discovered following the initial identification of their somatic mutations in APAs (Choi et al., 2011; Scholl et al., 2013), the discovery of the recurrent CACNA1H mutation relied entirely on brute force sequencing of patients with early severe aldosteronism and hypertension. Here, KCNJ5 is linked to hypertensive disorder.
