Variegate porphyria is an autosomal dominant inherited trait resulting in decreased activity of protoporphyrinogen oxidase. It is characterized clinically by photosensitive skin disease and a propensity to acute neurovisceral crises. The disease is found worldwide but has an exceptionally high frequency in South Africa.

ALAD porphyria is an autosomal recessive disorder resulting from a homozygous aminolevulinic acid dehydratase (ALAD) deficiency. Because of an almost complete lack of ALAD activity, patients excrete a large amount of ALA, but not PBG, into urine. The symptoms in this disease are similar to those seen in AIP, but ALAD porphyria can be differentiated ...

Blood Reviews, 1990
The porphyrias are a group of metabolic disorders arising from defects in the haem biosynthetic pathway. Most forms are inherited as Mendelian autosomal dominant characters, but some are recessive and others acquired. There is a linked group of diseases, which are not porphyrias, but have in common alterations of haem biosynthesis.

Current Treatment Options in Gastroenterology, 2000
The porphyrias are a diverse group of metabolic diseases. Major manifestations are episodic neurovisceral attacks of pain or other neurologic features, and/or dermatologic abnormalities. It is essential that a clear diagnosis be established prior to planning management.

Disease-a-Month, 1989
The porphyrias are metabolic disorders in which there are excessive accumulation and excretion of porphyrins and porphyrin precursors. Each of the porphyrias has a specific enzyme defect in the pathway of heme biosynthesis that explains the pattern of biochemical abnormalities that occur.

Clinics in Liver Disease, 1998
The porphyrias are metabolic disorders characterized by abnormal heme biosynthesis with excessive accumulation and excretion of porphyrias or porphyrin precursors. Defects in the enzymes of the heme biosynthetic pathway result in porphyria. Several of the disorders have been classified as hepatic because the major site of the biochemical defect has ...

Hepatoerythropoietic Porphyria
Archives of Dermatology, 1980In a case of hepatoerythropoietic porphyria (HEP) with unusual features, the patient had onset of photosensitivity in infancy, followed by spontaneous resolution of photosensitivity by the age of 7 years. Seven other cases of HEP have been found in the medical literature; the disease has systemic complications, mainly liver disease and anemia, and is ...

Annals of Internal Medicine, 1978
In temperate and cold climates the most usual presenting symptom of variegate porphyria is an acute porphyric attack, indistinguishable from that seen in acute intermittent porphyria. Increased fragility of the skin in sun-exposed areas occurs in only half of such patients, and even then is usually mild and easily overlooked.
