The HALT Progression of Polycystic Kidney Disease study concluded that strict blood pressure control with blockade of the renin-angiotensin system was associated with a slower kidney volume increase and greater reduction in the left ventricular mass index and urinary albumin excretion [23], shedding light on the blood pressure target of patients with ADPKD. The gene discussed is REN; the disease is polycystic kidney disease.
