From a cohort of more than 1500 unrelated subjects referred for evaluation of genetic forms of hypertension, we identified 40 subjects diagnosed with hypertension and PA by age 10 years in whom disease-causing mutations in CYP11B2, KCNJ5, and CACNA1D (Lifton et al., 1992; Choi et al., 2011; Scholl et al., 2013) were excluded. The gene discussed is KCNJ5; the disease is hypertensive disorder.
