The porphyrias are diseases caused by partial deficiencies of the enzymes of haem biosynthesis, most of which are inherited. Clinically, they are characterized by acute episodes of abdominal pain, sometimes with mental disturbances and neuropathy, or by skin disease, caused by photosensitization by porphyrins, or by both of these separately or together.
