The epithelial sodium channel in hypertension

Academic Article

Abstract

  • Our understanding of Na+ transport defects has exploded in the past several years, and has provided unique insights into epithelial transport processes, and unusual clinical syndromes resulting from mutations of specific ion transporters. These genetic disorders affect Na+ balance, with both Na+ retaining and Na+ wasting conditions being the consequence. A major focus of these studies has been the epithelial sodium channel (ENaC), which can be directly affected by mutations (eg, Liddle syndrome, autosomal recessive pseudohypoaldosteronism, type I) or by changes in the response to (autosomal recessive pseudohypoaldosteronism, type I), or production of mineralocorticoids (apparent mineralocorticoid excess syndrome, glucocorticoidremediable aldosteronism). As a result, we now have clearly defined syndromes in which ENaC activity is dysregulated with subsequent development of disorders of systemic blood pressure that can be attributed to a primary renal mechanism.
