Abstract:
      Liddle’s syndrome is a monogenic disease inherited in an autosomal dominant manner, and characterized by severe hypertension associated with low plasma renin, low blood potassium and hypokalemia. It is sensitive to the inhibitors of epithelial sodium channel (ENaC), but not to those of aldosterone. Though great advances have been made in its diagnosis and treatment, there are some patients being misdiagnosed and experiencing early cardiac and renal insufficiency or other target organ damage, stroke and even sudden death. In recent years, with the development of molecular biology and molecular genetics, some achievements are made in its pathogenic mechanism. The syndrome is due to a genetic mutation of ENaC, which causing over-activation of ENaC and increased sodium and water resorption in distal convoluted tubules. Once the diagnosis of Liddle’s syndrome is made, amiloride alone is adequate to control the hypertension. In this article, we reviewed the current researches on the syndrome.
