Common gene variants increase risk of hypertension, may lead to new therapies

... To search for hypertension-associated variants, the investigators focused on two genes called NPPA and NPPB that are involved in the production of atrial and B-type natriuretic peptides (ANP and BNP) proteins known to relax blood vessels and to be involved in the excretion of dietary sodium. Animals ...
