Mark where you are now
Erythropoietic Protoporphyria (EPP) is a rare inherited disorder caused by a deficiency in the enzyme ferrochelatase, leading to an accumulation of protoporphyrin in the blood, skin, and liver. This accumulation causes extreme sensitivity to sunlight, with even brief exposure leading to severe burning, stinging, and itching of the skin. Unlike sunburn, EPP reactions can occur within minutes of sun exposure and cause deep tissue pain.
