Summaries for Porphyria

MedlinePlus Genetics : 43 Porphyria is a group of disorders caused by abnormalities in the chemical steps that lead to heme production. Heme is a vital molecule for all of the body's organs, although it is most abundant in the blood, bone marrow, and liver. Heme is a component of several iron-containing proteins called hemoproteins, including hemoglobin (the protein that carries oxygen in the blood).Researchers have identified several types of porphyria, which are distinguished by their genetic cause and their signs and symptoms. Some types of porphyria, called cutaneous porphyrias, primarily affect the skin. Areas of skin exposed to the sun become fragile and blistered, which can lead to infection, scarring, changes in skin coloring (pigmentation), and increased hair growth. Cutaneous porphyrias include congenital erythropoietic porphyria, erythropoietic protoporphyria, hepatoerythropoietic porphyria, and porphyria cutanea tarda.Other types of porphyria, called acute porphyrias, primarily affect the nervous system. These disorders are described as "acute" because their signs and symptoms appear quickly and usually last a short time. Episodes of acute porphyria can cause abdominal pain, vomiting, constipation, and diarrhea. During an episode, a person may also experience muscle weakness, seizures, fever, and mental changes such as anxiety and hallucinations. These signs and symptoms can be life-threatening, especially if the muscles that control breathing become paralyzed. Acute porphyrias include acute intermittent porphyria and ALAD deficiency porphyria. Two other forms of porphyria, hereditary coproporphyria and variegate porphyria, can have both acute and cutaneous symptoms.The porphyrias can also be split into erythropoietic and hepatic types, depending on where damaging compounds called porphyrins and porphyrin precursors first build up in the body. In erythropoietic porphyrias, these compounds originate in the bone marrow. Erythropoietic porphyrias include erythropoietic protoporphyria and congenital erythropoietic porphyria. Health problems associated with erythropoietic porphyrias include a low number of red blood cells (anemia) and enlargement of the spleen (splenomegaly). The other types of porphyrias are considered hepatic porphyrias. In these disorders, porphyrins and porphyrin precursors originate primarily in the liver, leading to abnormal liver function and an increased risk of developing liver cancer.Environmental factors can strongly influence the occurrence and severity of signs and symptoms of porphyria. Alcohol, smoking, certain drugs, hormones, other illnesses, stress, and dieting or periods without food (fasting) can all trigger the signs and symptoms of some forms of the disorder. Additionally, exposure to sunlight worsens the skin damage in people with cutaneous porphyrias.

MalaCards based summary : Porphyria, also known as hematoporphyria, is related to porphyria cutanea tarda, type i and porphyria, congenital erythropoietic, and has symptoms including nausea and vomiting, constipation and abdominal pain. An important gene associated with Porphyria is HMBS (Hydroxymethylbilane Synthase), and among its related pathways/superpathways are Porphyrin and chlorophyll metabolism and Metabolism. The drugs Deferasirox and Colestipol have been mentioned in the context of this disorder. Affiliated tissues include skin, liver and bone marrow, and related phenotypes are abnormal urinary color and abnormal circulating porphyrin concentration

Disease Ontology : 12 An inherited metabolic disorder that involves certain enzymes in the heme bio-synthetic pathway resulting in the overproduction and accumulation of the porphyrins.

GARD : 20 Porphyrias are a group of blood conditions caused by a lack of an enzyme in the body that makes heme, an important molecule that carries oxygen throughout the body and is vital for all of the body's organs. Major types include ALAD deficiency porphyria, acute intermittent porphyria, congenital erythropoietic porphyria, erythropoietic protoporphyria, hepatoerythropoietic porphyria, hereditary coproporphyria, porphyria cutanea tarda, and variegate porphyria. The most common type of porphyria is porphyria cutanea tarda. Some of the symptoms of porphyria include blistering, swelling, and itching when the skin is exposed to sun. Other symptoms may also include pain, numbness or tingling, vomiting, constipation, and intellectual disability. There is no known cure for porphyria, but the various types have different courses of treatment, and may include bone marrow transplant. Most porphyrias are inherited conditions with either an autosomal dominant or autosomal recessive pattern of inheritance. However, some forms of porphyria can be caused by environmental factors such as infections or exposures to certain prescription drugs. Porphyrias caused by environmental factors are called sporadic or acquired porphyria.

MedlinePlus : 42 Porphyrias are a group of genetic disorders caused by problems with how your body makes a substance called heme. Heme is found throughout the body, especially in your blood and bone marrow, where it carries oxygen. There are two main types of porphyrias. One affects the skin and the other affects the nervous system. People with the skin type develop blisters, itching, and swelling of their skin when it is exposed to sunlight. The nervous system type is called acute porphyria. Symptoms include pain in the chest, abdomen, limbs, or back; muscle numbness, tingling, paralysis, or cramping; vomiting; constipation; and personality changes or mental disorders. These symptoms come and go. Certain triggers can cause an attack, including some medicines, smoking, drinking alcohol, infections, stress, and sun exposure. Attacks develop over hours or days. They can last for days or weeks. Porphyria can be hard to diagnose. It requires blood, urine, and stool tests. Each type of porphyria is treated differently. Treatment may involve avoiding triggers, receiving heme through a vein, taking medicines to relieve symptoms, or having blood drawn to reduce iron in the body. People who have severe attacks may need to be hospitalized. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

KEGG : 36 Porphyria is an inborn error of heme biosynthesis porphyrin metabolism caused by deficiency of enzymes of porphyrin metabolism. The intermediates of this pathway (porphyrinogens, porphyrins and their precursors) are produced in excess and accumulate in tissues, resulting in neurological and/or photocutaneous symptoms, and hematological disturbances. Porphyrias are divided into erythropoietic and hepatic according to the predominant porphyrin-accumulating tissue. Erythropoietic porphyrias include erythropoietic protoporphyria (EPP), congenital erythropoietic porphyria (CEP), and the very rare hepatoerythropoietic porphyria (HEP). Hepatic porphyrias include ALA-dehydratase deficiency porphyria (ADP), acute intermittent porphyria (AIP), porphyria cutanea tarda (PCT), hereditary coproporphyria (HCP), and variegate porphyria (VP). Recently, a new type of erythroid porphyria, X-linked dominant protoporphyria (XLDPP) has been reported.
