Distal Renal Tubular Acidosis with Hereditary Spherocytosis.

Hereditary spherocytosis (HS) and distal renal tubular acidosis (dRTA), although distinct entities, share the same protein i.e. the anion exchanger1 (AE1) protein. Despite this, their coexistence has been rarely reported. We hereby describe the largest family to date with coexistence of dRTA and HS and discuss the molecular basis for the co-inheritance of these conditions.
