Bartter syndrome 4B, neonatal, with sensorineural deafness (BARTS4B)2 Publications
The disease is caused by mutations affecting distinct genetic loci, including the gene represented in this entry. Loss-of-function of both CLCNKA and CLCNKB results in the disease phenotype (PubMed:18310267).1 Publication
Disease descriptionA digenic 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. BARTS4B is associated with sensorineural deafness.
