WebThe porphyrias are a group of metabolic disorders, each caused by impairment of one of the enzymes in the heme biosynthetic pathway (Figure 1). In affected people, buildup of specific pathway intermediates (porphyrins and porphyrin precursors) causes characteristic signs and symptoms. Most porphyrias are inherited disorders (Table 1). WebIf you have porphyria, cells fail to change chemicals in your body—called porphyrins and porphyrin precursors—into heme, the substance that gives blood its red color. When these chemicals build up in your body, they cause illness. fishing ice box
