    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. Acute intermittent porphyria - Wikipedia

    en.wikipedia.org/wiki/Acute_intermittent_porphyria

    Acute intermittent porphyria (AIP) is a rare metabolic disorder affecting the production of heme resulting from a deficiency of the enzyme porphobilinogen deaminase. It is the most common of the acute porphyrias .

  4. Gunther disease - Wikipedia

    en.wikipedia.org/wiki/Gunther_disease

    Günther disease is a congenital form of erythropoietic porphyria.The word porphyria originated from the Greek word porphura. Porphura actually means "purple pigment", which, in suggestion, the color that the body fluid changes when a person has Gunther's disease. [3]

  5. 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]

  6. 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.

  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

  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 ...
