There are four types of RTA: classic distal RTA (type I), proximal RTA (type II), hyperkalemic distal RTA (type IV), and a rare combination of proximal and distal RTA caused by carbonic anhydrase II deficiency and carbonic anhydrase inhibitors blocking the metabolism of bicarbonate and carbonic acid (type III). (bmj.com)

Common causes are hypotension or sepsis that causes renal hypoperfusion and nephrotoxic. (msdmanuals.com)

While the name clearly puts emphasis on ammonia production, ammoniagenesis produces "new" bicarbonate as well, which is actually the more important feature of ammoniagenesis in terms of acid base balance. (renalfellow.org)
While this is an intriguing hypothesis, a major gap in the field is that how the kidney actually senses changes in blood bicarbonate concentrations and responds with changes in ammonia production remains unknown. (renalfellow.org)
