Distal renal tubular acidosis with nerve deafness secondary to ATP6B1 gene mutation

Saudi J Kidney Dis Transpl. 2015 Jan;26(1):119-21. doi: 10.4103/1319-2442.148757.

Abstract

Autosomal recessive distal renal tubular acidosis (dRTA) is associated with mutation in the ATP6B1 gene encoding the B1 subunit of H + -ATPase, one of the key membrane transporters for net acid excretion of α-intercalated cells of medullary collecting ducts. Sensori-neural deafness frequently accompanies this type of dRTA. We herewith describe a patient who had distinct features of dRTA with bilateral sensori-neural hearing loss and ATP6B1 mutation. This is a rare entity.
