These include the (pro)renin receptor (5), renin-independent mechanisms of Ang peptide generation from Ang- (1-12) (6), intracellular (or intracrine) RAS that may contribute to cardiovascular disease (7, 8), and AT2 receptors (7) and the ACE2/Ang-(1-7)/Mas receptor pathway (6–8) that may mediate therapeutic benefit in cardiovascular disease. The gene discussed is ATP6AP2; the disease is cardiovascular disorder.
