What does UROD mean?
UROD: Uroporphyrinogen decarboxylase, an enzyme required for the synthesis of heme, a part of the hemoglobin molecule. UROD catalyses the decarboxylation of uroporphyrinogen III to coproporphyrinogen III by the conversion of four acetic acid groups to four methyl groups.
What does Uroporphyrinogen decarboxylase do?
Uroporphyrinogen decarboxylase (UROD) is a branch point enzyme in the biosynthesis of the tetrapyrroles. It catalyzes the decarboxylation of four acetate groups of uroporphyrinogen III to yield coproporphyrinogen III, leading to heme and chlorophyll biosynthesis.
What is the function of purpose of Uroporphyrinogen decarboxylase?
Uroporphyrinogen III decarboxylase is a homodimeric enzyme (PDB: 1URO) that catalyzes the fifth step in heme biosynthesis, which corresponds to the elimination of carboxyl groups from the four acetate side chains of uroporphyrinogen III to yield coproporphyrinogen III: uroporphyrinogen III.
What is the most common porphyria?
Porphyria cutanea tarda (PCT) is the most common type of all the porphyrias. As a result of sun exposure, you may experience: Sensitivity to the sun and sometimes artificial light, causing burning pain.
What is Gunther’s disease?
Congenital erythropoietic porphyria (CEP or Gunther disease) is an extremely rare subtype of the non-acute group, estimating a prevalence of <0.9 in 1 000 000 [1, 2]. All organs are vulnerable to the porphyrin accumulation effects, but the most affected ones are the skin, hematopoietic system, teeth, bones and sclera.
What is congenital erythropoietic porphyria?
Congenital erythropoietic porphyria (CEP) is a very rare inherited metabolic disorder resulting from the deficient function of the enzyme uroporphyrinogen III synthase (UROS), the fourth enzyme in the heme biosynthetic pathway.
Why is there no anemia in porphyria?
Physiologically, porphyrias are classified as liver or erythropoietic based on the sites of accumulation of heme precursors, either in the liver or in the bone marrow and red blood cells. Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme.
What causes erythropoietic Protoporphyria?
Erythropoietic protoporphyria (EPP) is a rare inherited metabolic disorder caused by a deficiency of the enzyme ferrochelatase (FECH), which results from changes (mutations) in the FECH gene.
What causes congenital porphyria?
Erythropoietic porphyria is caused by autosomal recessive inheritance of genes that encode abnormal uroporphyrinogen III synthase (UROS) enzyme protein. The resultant deficient activity of this enzyme leads to hemolytic anemia, cutaneous photosensitivity, and their complications.
Does porphyria cause anemia?
Anemia. Two types of cutaneous porphyria, congenital erythropoietic porphyria and, less commonly, hepatoerythropoietic porphyria, may cause severe anemia. These diseases may also cause the spleen to become enlarged, which can make anemia worse.
What is porphyria in cats?
Congenital erythropoietic porphyria is a rare hereditary disease of cats, cattle, pigs, sheep, and people. It results from low levels of an enzyme involved in the production of heme. Heme is a part of hemoglobin, which is the molecule that carries oxygen in the blood.
Which one of the following is a type of erythropoietic porphyria?
Types
| Name | OMIM | Gene |
|---|---|---|
| erythropoietic protoporphyria (EPP) | 177000 | ferrochelatase |
| congenital erythropoietic porphyria or “Gunther’s” (CEP) | 263700 | uroporphyrinogen III synthase |
| hepatoerythropoietic porphyria | 176100 | uroporphyrinogen III decarboxylase |
Is erythropoietic Protoporphyria rare?
Erythropoietic protoporphyria (EPP) is an inherited disorder of the haem metabolic pathway characterised by accumulation of protoporphyrin in blood, erythrocytes and tissues, and cutaneous manifestations of photosensitivity. EPP has been reported worldwide, with prevalence between 1:75,000 and 1:200,000.
Is Porphyria a blood disease?
Porphyrias are a group of rare inherited blood disorders. People with these disorders have problems making a substance called heme in their bodies.
Is Protoporphyria recessive?
Erythropoietic protoporphyria (EPP) is inherited in an autosomal recessive manner.
Is Protoporphyria dominant or recessive?
Inheritance of the Porphyrias
| Type | Inheritance | Gene |
|---|---|---|
| Hepatoerythropoietic Porphyria (HEP) | Autosomal recessive | UROD |
| Hereditary Coproporphyria (HCP) | Autosomal dominant | CPOX |
| Variegate Porphyria (VP) | Autosomal dominant | PPOX |
| Erythropoietic Protoporphyria (EPP) X-linked Protoporphyria (XLP) | Autosomal recessive X-linked | FECH ALAS2 |
How common is erythropoietic Protoporphyria?
Erythropoietic Protoporphyria affects males and females in equal numbers. It is estimated that the disorder occurs in about 1 in about 74,300 individuals.
Is Protoporphyria dominant?
X-linked protoporphyria is caused by mutations of the ALAS2 gene and is inherited in an X-linked dominant pattern.
Is Porphyria a mental illness?
Acute intermittent porphyria mimics a variety of commonly occurring disorders and thus poses a diagnostic quagmire. Psychiatric manifestations include hysteria, anxiety, depression, phobias, psychosis, organic disorders, agitation, delirium, and altered consciousness ranging from somnolence to coma.
How do you test for porphyria?
To diagnose porphyrias, laboratories measure porphyrins and their precursors in urine, blood, and/or stool. Testing may include measurement of one or more of the following: Porphobilinogen (PBG), a porphyrin precursor, in urine. Delta-aminolevulinic acid (ALA), another porphyrin precursor, in urine.
How many cases of porphyria are there?
Frequency. The exact prevalence of porphyria is unknown, but it probably ranges from 1 in 500 to 1 in 50,000 people worldwide. Overall, porphyria cutanea tarda is the most common type of porphyria.
Is Porphyria a disability?
People who are trying to win benefits for porphyria need to meet certain criteria in the Social Security Blue Book, which outlines the disability benefits for a wide variety of conditions. People with cutaneous porphyria can gain benefits under Skin Disorders or Genetic Photosensitive Disorders.
What part of the body does porphyria affect?
Porphyria occurs when the body cannot convert compounds called ‘porphyrins’ into heme. While all tissues have heme, those that use it the most are the red blood cells, liver and bone marrow. Porphyria can affect the skin, nervous system and gastrointestinal system. More women than men are affected by porphyria.
Is porphyria an autoimmune disease?
The aetiology of porphyria cutanea tarda (PCT) has not been elucidated, but the possibility of an autoimmune mechanism has been proposed. We report a case of an unknown clinical combination of PCT with autoimmune hypothyroidism, alopecia universalis and vitiligo with thyroid and parietal cell circulating antibodies.
When should you suspect porphyria?
Therefore, it is currently recommended that patients undergo screening by liver imaging for early detection at least yearly after age 50, especially if porphobilinogen (PBG) remains elevated. The American Porphyria Foundation is a valuable source of additional advice.
What medications should be avoided with porphyria?
Which medications should be avoided by patients with porphyria?
- Barbiturates.
- Anticonvulsants.
- Progestins.
- Rifampin.
How is porphyria treated?
Treatment for acute porphyria involves intravenous (IV) heme or glucose infusions (adding heme or glucose directly into a vein). These therapies decrease the number of porphyrins or porphyrin precursors produced in the liver. Other drugs are under investigation and may be available through clinical trials.
Can porphyria cause weight gain?
“Unfortunately, because of the therapeutic high carbohydrate intake, patients with hepatic porphyrias are prone to weight gain. Losing excess weight is very difficult for some of these patients because of fasting-induced acute attacks.
