Autosomal recessive distal renal tubular acidosis caused by G701D mutation of anion exchanger 1 gene
Anion exchanger 1 (AE1 or band 3), encoded by the AE1 or SLC4A1 gene, regulates chloride-bicarbonate exchange in erythrocytes and α-intercalated cells of the distal nephron. Defects of AE1 at the basolateral membrane of α-intercalated cells may result in the failure of hydrogen ion secretion at the...
