  2. Porphyria - Wikipedia

    en.wikipedia.org/wiki/Porphyria

    Porphyria Cutanea Tarda (PCT): PCT is the most common form of porphyria, with an estimated prevalence of 1 to 2 cases per 10,000 individuals in the general population. It predominantly affects adults, with a higher prevalence in men than in women.

  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.

  4. 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 .

  5. Variegate porphyria - Wikipedia

    en.wikipedia.org/wiki/Variegate_porphyria

    Variegate porphyria is inherited in an autosomal dominant pattern, which means the defective gene is located on an autosome, and inheriting one copy of the defective gene from an affected parent is sufficient to cause the disorder. More severe cases result from inheriting two copies of the defective gene.

  6. Aminolevulinic acid dehydratase deficiency porphyria - Wikipedia

    en.wikipedia.org/wiki/Aminolevulinic_acid_de...

    Aminolevulinic acid dehydratase deficiency porphyria (also known as Doss porphyria, [1] plumboporphyria, [1] or ADP [2]) is an extremely rare autosomal recessive metabolic disorder that results from inappropriately low levels of the enzyme delta-aminolevulinic acid dehydratase (), which is required for normal heme synthesis.

  7. 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]

  8. 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. 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.
