Summaries for Bartter Syndrome, Type 3

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 93605DefinitionClassic Bartter syndrome is a type of Bartter syndrome (see this term), 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.EpidemiologyExact prevalence of Classic Bartter syndrome is not known. It is by far the most frequent type of Bartter syndrome.Clinical descriptionClassic Bartter syndrome is characterized by a milder clinical picture with a wide phenotypic heterogeneity when compared to other subtypes of Bartter syndrome. Only one third of the patients present with maternal polyhydramnios which usually does not lead to prematurity. Patients usually present after neonatal period with failure to thrive, fatigue, muscle weakness, cramps and carpopedal spasms. Hypokalemia and alkalosis are common. Polyuria and hypostenuria/isosthenuria are variable, as is hypercalciuria. Few patients develop medullary nephrocalcinosis.EtiologyMutation in CLCNKB gene (1p36), encoding a basolateral chloride channel ClCKb, has been identified as the most frequent cause of classic Bartter syndrome. Both the chloride channels, ClCKa and ClCKb are expressed in thick ascending limb of the loop of Henle (TALH), ClCKa is exclusively expressed in the ascending limb, while ClCKb is also expressed in distal convoluted tubule (DCT), thereby explaining the pronounced DCT features (similar to Gitelman syndrome; see this term) in some patients with CLCNKB mutations. CLCNKB mutations define classic Bartter syndrome; however, genes other than CLCNKB (those that are usually associated with other types of Bartter syndrome) may less commonly cause the classic, less severe phenotype, such as SLC12A1 and KCNJ1. Rarely, patients with BSND mutation may show a mild phenotype of salt loss associated with deafness.Diagnostic methodsDiagnosis is based on the clinical picture, plasma and urine electrolytes (sodium, potassium, chloride, bicarbonate, magnesium, calcium), renin and aldosterone levels. Calcium levels in the urine may be normal or slightly increased. Genetic testing provides the definite diagnosis.Differential diagnosisThe differential diagnosis includes pseudo-Bartter syndrome (diuretic abuse, surreptitious vomiting), cystic fibrosis, Gitelman syndrome, and celiac disease (see these terms).Antenatal diagnosisDiagnostic testing of amniocytes might be indicated for mothers of affected children, or potential heterozygous carriers (close relatives of affected individuals).Genetic counselingInheritance is autosomal recessive.Management and treatmentTreatment includes oral potassium supplements, non-steroidal anti-inflammatory drugs (e.g. indometacin) and possibly potassium-sparing diuretics. In stressful situations (additional diseases, surgical procedures, trauma) blood electrolyte levels may change rapidly, requiring prompt and vigorous treatment.PrognosisLife expectancy may be reduced in severe cases but renal failure is rare. Quality of life may be poor, growth rate reduced, and medicalization/hospitalization rate high.Visit the Orphanet disease page for more resources.

MalaCards based summary : Bartter Syndrome, Type 3, also known as bartter syndrome type 3, is related to bartter syndrome, type 4b, neonatal, with sensorineural deafness and polyhydramnios, and has symptoms including generalized muscle weakness and polyuria. An important gene associated with Bartter Syndrome, Type 3 is CLCNKB (Chloride Voltage-Gated Channel Kb), and among its related pathways/superpathways is Diuretics Pathway, Pharmacodynamics. Affiliated tissues include testes, kidney and retina, and related phenotypes are hypocalciuria and hypotension

Disease Ontology : 12 A Bartter disease that has material basis in homozygous or compound heterozygous mutation in the kidney chloride channel B gene (CLCNKB) on chromosome 1p36.

OMIM : 57 Bartter syndrome refers to a group of disorders that are unified by autosomal recessive transmission of impaired salt reabsorption in the thick ascending loop of Henle with pronounced salt wasting, hypokalemic metabolic alkalosis, and hypercalciuria. Clinical disease results from defective renal reabsorption of sodium chloride in the thick ascending limb (TAL) of the Henle loop, where 30% of filtered salt is normally reabsorbed (Simon et al., 1997). Patients with antenatal (or neonatal) forms of Bartter syndrome (e.g., BARTS1, 601678) typically present with premature birth associated with polyhydramnios and low birth weight and may develop life-threatening dehydration in the neonatal period. Patients with classic Bartter syndrome present later in life and may be sporadically asymptomatic or mildly symptomatic (summary by Simon et al., 1996 and Fremont and Chan, 2012). (607364)

UniProtKB/Swiss-Prot : 74 Bartter syndrome 3: A form of Bartter syndrome, an autosomal recessive disorder characterized by impaired salt reabsorption in the thick ascending loop of Henle with pronounced salt wasting, hypokalemic metabolic alkalosis, and varying degrees of hypercalciuria.
