Primary Distal Renal Tubular Acidosis
How common is primary distal renal tubular acidosis?
Primary distal renal tubular acidosis (primary dRTA) is known to be a rare genetic condition, but the exact incidence of primary dRTA is unknown. It is known that individuals of North African (primarily Tunisia), Greek Cypriot, and Middle Eastern descent have an increased frequency of primary dRTA caused by changes in the ATP6V1B1 gene. Individuals from Northeast Thailand, Thailand, Malaysia, the Philippines, and Papua New Guinea have an increased frequency of primary dRTA and anemia caused by two changes in the SLC4A1 gene.
