Genetic analysis revealed mutations in several genes associated with Bartter syndrome (BS) and Gitelman syndrome, including SLC12A1, CLCNKB, CASR, SLC26A3, and SLC12A3. Prostaglandin E2 (PGE2) plays an important role in BS and worsens electrolyte abnormalities. This evidence concerns the gene SLC12A3 and Bartter syndrome.
