renal tubular acidosis, distal, autosomal dominant

An autosomal dominant condition (OMIM:179800) characterised by a reduced ability to acidify urine, resulting in variable hyperchloremic hypokalaemic metabolic acidosis, nephrocalcinosis and nephrolithiasis.

Molecular pathology
Caused by defects of SLC4A1, which encodes a protein with a glycosylated C-terminal membrane-associated domain that acts as an anion exchange transporter binding carbonic anhydrase II.

Renal tubular acidosis is characterized by a normal anion gap hyperchloremic metabolic acidosis; plasma potassium may be normal, low or high-depending on the type of RTA.
The mechanism by which Sjogren's Syndrome leads to distal renal tubular acidosis is incompletely understood.
