Hypertension.

Abstract

The monogenic forms of human hypertension have yielded to the power of modern genetic techniques in the last several years. With the successful expression cloning of the subunits of the epithelial sodium channel, a whole era has evolved in our basic understanding of the low renin forms of human hypertension. Of note, all of these hypertensive syndromes (Liddle's syndrome, glucocorticoid-remediable aldosteronism, and the apparent mineralocorticoid excess syndrome) share an underlying dysregulation of the activity of the epithelial sodium channel in the cortical collecting tubule. Loss of function defects due to mutations in the channel subunits themselves, or in the mineralocorticoid receptor (pseudohypoaldosteronism, type I) also affect blood pressure regulation consequent to renal salt wasting and dysregulation of the epithelial sodium channel in the cortical collecting tubule.
