Bartter Syndrome
A group of inherited salt-wasting kidney tubule disorders, caused by genes such as SLC12A1, KCNJ1, CLCNKB, BSND and CASR, with low potassium, metabolic alkalosis and high urine calcium.
What a diagnosis changes
Knowing guides salt and potassium replacement and monitoring of growth and kidney calcification.
Also known as
Bartter disease; Bartter's syndrome; hypokalemic alkalosis; hypokalemic alkalosis with hypercalciuria; Potassium wasting; renal tubular normotensive hypokalemic alkalosis with hypercalciuria; salt-losing tubular disorder, Henle's loop type; salt-wasting tubulopathy, Henle's loop type
Specific forms also covered
Bartter Disease Type 1
Autosomal recessive
Bartter Disease Type 2
Autosomal recessive
Any Bartter syndrome in which the cause of the disease is a mutation in the KCNJ1 gene.
Bartter Disease Type 3
Autosomal recessive
Classic Bartter syndrome is a type of Bartter syndrome, characterized by a milder clinical picture than the antenatal/infantile subtype, and presenting with failure to thrive, hypokalemic alkalosis, increased levels of plasma renin and aldosterone, low blood pressure and vascular resistance to angiotensin II.
Bartter Syndrome Type 4
Autosomal recessive
A form of Bartter syndrome characterized by maternal polyhydramnios, premature delivery, salt loss, polyuria and sensorineural deafness, associated with hypokalemic and hypochloremic metabolic alkalosis, increased levels of plasma renin and aldosterone, and low to normal blood pressure. Urinary calcium excretion rates are variable, and nephrocalcinosis is typically absent.
Bartter Disease Type 5
X-linked recessive
Any Bartter syndrome in which the cause of the disease is a mutation in the MAGED2 gene.
