  • Protoporphyria, erythropoietic, 1 (EPP1) [MIM:177000]: An autosomal recessive form of porphyria with onset usually before age 10 years. Porphyrias are inherited defects in the biosynthesis of heme, resulting in the accumulation and increased excretion of porphyrins or porphyrin precursors. They are classified as erythropoietic or hepatic, depending on whether the enzyme deficiency occurs in red blood cells or in the liver. Erythropoietic protoporphyria is marked by excessive protoporphyrin in erythrocytes, plasma, liver and feces, and by widely varying photosensitive skin changes ranging from a burning or pruritic sensation to erythema, edema and wheals. {ECO:0000269 PubMed:10942404, ECO:0000269 PubMed:11375302, ECO:0000269 PubMed:12063482, ECO:0000269 PubMed:12601550, ECO:0000269 PubMed:1376018, ECO:0000269 PubMed:15286165, ECO:0000269 PubMed:17196862, ECO:0000269 PubMed:1755842, ECO:0000269 PubMed:7910885, ECO:0000269 PubMed:8757534, ECO:0000269 PubMed:9211198, ECO:0000269 PubMed:9585598, ECO:0000269 PubMed:9740232}.
