OMIA 000836-9031 : Protoporphyria in Gallus gallus

In other species: cattle

Possibly relevant human trait(s) and/or gene(s) (MIM number): 177000

Mendelian trait/disorder: yes

Considered a defect: yes

Key variant known: no

Cross-species summary: Protoporphyrin is the last intermediate in the seven-step biosynthesis of haem from aminolaevulinic acid (ALA). The conversion of protoporphyrin to haem is catalised by the enzyme ferrochelatase. Protoporphyria is a disorder resulting from the buildup of protoporphyrin (and the other five, earlier intermediates [porphyrins] in this pathway: see the entry for porphyria, unclassified), due to the lack of this enzyme. Protoporphyrin is extremely photoreactive. Because of this, photosensitivity is the main clinical sign of this disorder.
