Summaries for Bartter Syndrome, Type 2, Antenatal

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 forms of Bartter syndrome 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 (see BARTS3, 607364) present later in life and may be sporadically asymptomatic or mildly symptomatic (summary by Simon et al., 1996 and Fremont and Chan, 2012). For a discussion of genetic heterogeneity of Bartter syndrome, see 607364. (241200)

MalaCards based summary : Bartter Syndrome, Type 2, Antenatal, also known as hyperprostaglandin e syndrome 2, is related to antley-bixler syndrome without genital anomalies or disordered steroidogenesis and biemond syndrome ii, and has symptoms including seizures, constipation and fever. An important gene associated with Bartter Syndrome, Type 2, Antenatal is KCNJ1 (Potassium Voltage-Gated Channel Subfamily J Member 1), and among its related pathways/superpathways are Taste transduction and CFTR-dependent regulation of ion channels in Airway Epithelium (norm and CF). Affiliated tissues include eye, and related phenotypes are macrocephaly and frontal bossing

Disease Ontology : 12 A Bartter disease that has material basis in homozygous or compound heterozygous mutation in the potassium channel ROMK gene (KCNJ1) on chromosome 11q24.

UniProtKB/Swiss-Prot : 75 Bartter syndrome 2, antenatal: 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. BARTS2 is a life- threatening condition beginning in utero, with marked fetal polyuria that leads to polyhydramnios and premature delivery. Another hallmark is a marked hypercalciuria and, as a secondary consequence, the development of nephrocalcinosis and osteopenia.
