Acute intermittent porphyria (AIP) is a rare autosomal dominant metabolic disorder affecting the production of heme, the oxygen-binding prosthetic group of hemoglobin. It is characterized by a deficiency of the enzyme porphobilinogen deaminase. Acute intermittent porphyria is the second most common form of porphyria (porphyria cutanea tarda being the most common).:525 Its incidence is estimated to be between 5 and 10 in 100,000, but this is likely underestimated because of positive cases not being induced, and long periods of latency, with an estimation that it is latent in 90% of cases.
