WebPorphyrias are a group of rare disorders. An important part of hemoglobin, called heme, is not made properly. Heme is also found in myoglobin, a protein found in certain muscles. There are seven types of porphyria, and each one is associated with a different enzyme deficiency. Most porphyrias are inherited, the result of a gene mutation.
