Pathway Description
Hereditary Coproporphyria (HCP)
Mus musculus
Disease Pathway
Hereditary coproporphyria (HCP) is a rare inborn error of metabolism (IEM) which arises from a defective gene called CPOX. This gene is responsible for mitochondrial coproporphyrinogen-III oxidase. A defect in this enzyme results in accumulation of the porphyrin precursors porphobilinogen and 5-aminolevulinic acid; increase of fecal and urinary excreation of coproporphyrins. Symptoms for this condition vary substantially, with anything from reddish-purple urine, to bouts of acute abdominal and nerve pain, to episodes of photosensitive skin eruptions so extreme that the induced scratching often leads to permanent scarring. At the present time the condition has no cure. The following are some measures which are designed to help prevent and/or regulate the above and more symptoms: a diet which is high in carbohydrates and sugars, and a balanced lifestyle which abstains from alcohol and drug use.
