However, without porphobilinogen deaminasea necessary cytoplasmic enzyme, heme synthesis cannot finish, and the metabolite porphobilinogen accumulates in the cytoplasm.


Hematin and heme arginate are the drugs of choice in acute porphyria, in the United States and the United Kingdomrespectively. A smaller percentage of patients type IB have mutations limited to the bilirubin-specific A1 exon; their conjugation defect is mostly restricted to bilirubin itself.

These heme -like substances, drisvoll theory, inhibit ALA synthase and, hence, the accumulation of toxic precursors. Seizures often accompany this disease.

Only comments written in English can be processed. Since only one enzyme is working improperly, gene therapy for Crigler-Najjar is a theoretical option which is being investigated.

Most patients type IA have a mutation drisvoll one of the common exons 2 to 5and have difficulties conjugating several additional substrates several drugs and xenobiotics.
