Hereditary coproporphyria Causes

Coproporphyria is the result of a combination of a genetic enzyme defect and acquired causes that become symptomatic in rare cases. In individuals with coproporphyria, the function of coproporphyrinogen oxidase is only 40-60% of normal. Also, most patients with defects in coproporphyrinogen oxidase never display any symptoms. The typical inducers of porphyria are chemicals or situations that boost heme synthesis. This includes fasting and many medications, among others.
