Variants resulting in constitutive activation of epithelial sodium channel activity have been demonstrated in the beta and gamma subunits as the cause of the autosomal dominant form of hypertension, Liddle syndrome, which is characterized by volume expansion, hypokalemia, and alkalosis.
Variants causing loss of epithelial sodium channel activity cause the converse phenotype of volume depletion, hyperkalaemia and acidosis characteristic of patients with pseudohypoaldosteronism type I.
