Title: A family with liddle's syndrome caused by a mutation in the beta subunit of the epithelial sodium channel. Author: Kyuma M, Ura N, Torii T, Takeuchi H, Takizawa H, Kitamura K, Tomita K, Sasaki S, Shimamoto K. Journal: Clin Exp Hypertens; 2001 Aug; 23(6):471-8. PubMed ID: 11478429. Abstract: Liddle's syndrome is a rare form of autosomal-dominant salt-sensitive hypertension. Constitutive activation of the amiloride-sensitive distal renal epithelial sodium channel (ENaC) is essential for salt-sensitive hypertension. Recently, several DNA analysis studies have indicated that there is a mutation of C-terminus of either the beta or y subunit. We sequenced the C-termini of the beta and -gamma subunits of the ENaC in a Japanese family with hypertension and hypopotassemia without excess minerarocorticoids, clinically diagnosed as Liddle's syndrome. The mutation of the ENaC of this family was beta R564X. Since such case seem to be rare in the literature, detailed data are shown in this report.[Abstract] [Full Text] [Related] [New Search]
