A case series of distal renal tubular acidosis, Southeast Asian ovalocytosis and metabolic bone disease.

Background: Familial distal renal tubular acidosis (dRTA) associated with mutations of solute carrier family 4 membrane - 1 (SLC4A1) gene could co-exist with red cell membrane abnormality, Southeast Asian ovalocytosis (SAO). Although this association is well described in Southeast Asian countries, it is less frequently found in Sri Lanka.

Case Presentation: We describe six patients who had dRTA co-existing with SAO.
