In a cohort of patients with suspected Bartter syndrome, WES identified no candidate variants in Bartter-associated genes but instead found a variation in SLC26A3. Variants in this gene are associated with chloride diarrhea, and clinical follow-up confirmed the diagnosis of chloride diarrhea in these patients (Choi et al., 2009). This evidence concerns the gene SLC26A3 and Bartter syndrome.
