WebAcute Intermittent Porphyria (AIP) Acute Intermittent Porphyria (AIP) is a rare metabolic disorder that is characterized by deficiency of the enzyme hydroxymethylbilane synthase (HMBS), also known as porphobilinogen deaminase (PBGD). This enzyme deficiency can result in the accumulation of toxic porphyrin precursors in the body. WebEuropean Medicines Agency -
WebMay 8, 2024 · This deficiency is noticeable in the acute attacks, where the heme pool in the liver gets used, and there is the induction of delta-aminolevulinic acid synthase (ALAS1). This process leads to delta-aminolevulinic (ALA) accumulation and porphobilinogen (PBG), which are the immediate precursors proximal to the HMBS. WebAcute intermittent porphyria (AIP) is one of the liver (hepatic) porphyrias. AIP is caused by low levels of porphobilinogen deaminase (PBGD), an enzyme also often called …
