Summaries for FECH Gene

Entrez Gene Summary for FECH Gene

  • The protein encoded by this gene is localized to the mitochondrion, where it catalyzes the insertion of the ferrous form of iron into protoporphyrin IX in the heme synthesis pathway. Mutations in this gene are associated with erythropoietic protoporphyria. Two transcript variants encoding different isoforms have been found for this gene. A pseudogene of this gene is found on chromosome 3.[provided by RefSeq, May 2010]

  • Erythropoietic protoporphyria (EPP) [MIM:177000]: A form of porphyria. 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}.
