Primary causes of renal tubular acidosis include genetic mutations causing defects in the kidney anion exchanger [kAE1] in distal tubule intercalated cells and congenital adrenal hyperplasia. Secondary causes include medications and autoimmune diseases.

Causes

The following table summarizes the common primary and secondary causes of renal tubular acidosis.^[1]^[2]^[3]

	Primary Causes	Secondary Causes
Type 1	Idiopathic Familial Autosomal dominant Mainly due to mutations causing defects in the kidney anion exchanger [kAE1] in distal tubule intercalated cells. Autosomal recessive Mainly due to mutations causing defects in V-ATPase in distal tubule intercalated cells.	Autoimmune disorders Medications Ifosfamide Amphotericin B Lithium carbonate Ibuprofen Hypercalciuric conditions Hyperparathyroidism Vitamin D intoxication Sarcoidosis Idiopathic hypercalciuria Others
Type 2	Recessive Proximal tubule cell sodium bicarbonate co-transporter (NBCe1) defect Carbonic anhydrase type 2 deficiency Cystinosis Tyrosinemia Hereditary fructose intolerance Galactosemia Glycogen storage disease (type I) Lowe syndrome	M-protein disorders Amyloidosis Multiple myeloma Medications Ifosfamide Tenofovir Acetazolamide Topiramate Aminoglycosides Heavy metals Lead Cadmium Mercury Copper Other Medullary sponge kidney Obstructive uropathy Renal transplant rejection Wilson disease
Type 4	Congenital hypoaldosteronism 21-hydroxylase deficiency Isolated hypoaldosteronism Pseudohypoaldosteronism type 2 Primary adrenal insufficiency Pseudohypoaldosteronism type 1	Angiotensin inhibitors, such as ACE inhibitors Angiotensin II receptor blockers Direct renin inhibitors Antibiotics, trimethoprim, and pentamidine Potassium-sparing diuretics Spironolactone Eplerenone Amiloride Triamterene
