Type : Phenotype, molecular basis known;

Alternative titles and symbols : FHHT; Familial hyperkalemic hypertension;

Description : Familial hyperkalemic hypertension, also known as type II pseudohypoaldosteronism (PHAII) or Gordon syndrome, is a rare autosomal dominant disease in which a net positive sodium ion balance is associated with renal potassium ion retention, resulting in hypertension, hyperkalemia, and hyperchloremic metabolic acidosis (summary by Louis-Dit-Picard et al., 2012). - Genetic Heterogeneity of Type II Pseudohypoaldosteronism For a discussion of genetic heterogeneity of type II pseudohypoaldosteronism, see PHA2A (145260).;

Inheritance : Autosomal dominant; Autosomal recessive;

Molecular basis : Caused by mutation in the kelch-like 3 gene (KLHL3, 605775.0001);

Laboratory abnormalities : Hyperkalemia ( 6.2 mM in both dominant and recessive); Hyperchloremia (mean 110 mM in both dominant and recessive);

Prefixed ID : #614495;
