Molecular analysis of acute intermittent porphyria: mutation screening in 20 patients in Germany reveals 11 novel mutations.

Abstract excerpt

Acute intermittent porphyria (AIP) is a very rare autosomal dominant disorder with low penetrance. Mutations in the gene of the porphobilinogen deaminase (PBG-D), also called hydroxymethylbilane synthase (HMBS), cause a partial deficiency of this enzyme of the heme biosynthetic pathway. Overstimulation of heme biosynthesis causes clinical symptoms. Because of the variability of the symptoms, diagnosis is often...
