  2. Porphyria - Wikipedia

    en.wikipedia.org/wiki/Porphyria

    Porphyria / p ɔːr ˈ f ɪr i ə / is a group of disorders in which substances called porphyrins build up in the body, adversely affecting the skin or nervous system. [1] The types that affect the nervous system are also known as acute porphyria, as symptoms are rapid in onset and short in duration. [1]

  3. Porphyria cutanea tarda - Wikipedia

    en.wikipedia.org/wiki/Porphyria_cutanea_tarda

    Porphyria cutanea tarda is the most common subtype of porphyria. [1] The disease is named because it is a porphyria that often presents with skin manifestations later in life. The disorder results from low levels of the enzyme responsible for the fifth step in heme production. Heme is a vital molecule for all of the body's organs.

  4. Erythropoietic protoporphyria - Wikipedia

    en.wikipedia.org/wiki/Erythropoietic_protoporphyria

    Erythropoietic protoporphyria (or commonly called EPP) is a form of porphyria, which varies in severity and can be very painful.It arises from a deficiency in the enzyme ferrochelatase, leading to abnormally high levels of protoporphyrin in the red blood cells (erythrocytes), plasma, skin, and liver. [2]

  5. Acute intermittent porphyria - Wikipedia

    en.wikipedia.org/wiki/Acute_intermittent_porphyria

    If drugs have caused the attack, discontinuing the offending substances is essential. A high-carbohydrate (10% glucose) infusion is recommended, which may aid in recovery. [citation needed] Hemin(Hematin) Hematin and heme arginate is the treatment of choice during an acute attack. Heme is not a curative treatment, but can shorten attacks and ...

  6. Hereditary coproporphyria - Wikipedia

    en.wikipedia.org/wiki/Hereditary_coproporphyria

    Hereditary coproporphyria (HCP) is a disorder of heme biosynthesis, classified as an acute hepatic porphyria. [1] HCP is caused by a deficiency of the enzyme coproporphyrinogen oxidase, coded for by the CPOX gene, and is inherited in an autosomal dominant fashion, although homozygous individuals have been identified.

  7. Hepatic porphyria - Wikipedia

    en.wikipedia.org/wiki/Hepatic_porphyria

    Hepatic porphyrias is a form of porphyria in which toxic porphyrin molecules build up in the liver. Hepatic porphyrias can result from a number of different enzyme deficiencies. [1] Examples include (in order of synthesis pathway): [citation needed] Acute intermittent porphyria; Porphyria cutanea tarda and Hepatoerythropoietic porphyria

  8. List of skin conditions - Wikipedia

    en.wikipedia.org/wiki/List_of_skin_conditions

    Skin conditions resulting from errors in metabolism are caused by enzymatic defects that lead to an accumulation or deficiency of various cellular components, including, but not limited to, amino acids, carbohydrates, and lipids. [16] Acute intermittent porphyria; Adrenoleukodystrophy (Schilder's disease) Alkaptonuria

  9. Variegate porphyria - Wikipedia

    en.wikipedia.org/wiki/Variegate_porphyria

    Variegate porphyria has an autosomal dominant pattern of inheritance. Mutations in the PPOX gene cause variegate porphyria. [4] The PPOX gene makes a membrane bound mitochondrial enzyme called protoporphyrinogen oxidase, which is critical to the chemical process that leads to heme production. The activity of this enzyme is reduced by 50 percent ...
