Recessive loss-of-function mutations in genes involved in renal NaCl handling cause rare diseases characterized by salt wasting and reduced blood pressure of variable severity. A new study shows that the carrier state for rare inactivating mutations in three genes involved in NaCl transport in the kidney is associated with a significant blood pressure reduction and a reduced risk of hypertension in the general population.
