Abstract

Mutations in the hydroxymethylbilane synthase (HMBS) gene are responsible for the inherited disorder of acute intermittent porphyria (AIP). AIP is diagnosed on the basis of characteristic clinical symptoms, elevated levels of urinary porphyrin precursors aminolevulinic acid (ALA) and porphobilinogen (PBG) and a decreased erythrocytic HMBS activity, although an identifiable HMBS mutation provides the ultimate proof for AIP.
