Porphyria • Porphyria is a group of rare genetic disorders, in which an important part of hemoglobin, called Heme, is not made properly. • There are many different forms of this. The most common type is porphyria cutanea tarda (PCT).
Causes • Normally, the body makes heme in a many-step process. Porphyrins are made during several steps of this process. Patients with porphyria have a deficiency of certain enzymes needed for this process. This causes abnormal amounts of porphyrins or related chemicals to build up in the body (the excess skin or bubbles).
