An autosomal dominant porphyria that is due to a deficiency of COPROPORPHYRINOGEN OXIDASE in the LIVER, the sixth enzyme in the 8-enzyme biosynthetic pathway of HEME. Clinical features include both neurological symptoms and cutaneous lesions. Patients excrete increased levels of porphyrin precursors, 5-AMINOLEVULINATE and COPROPORPHYRINS.
Porphyrins with four methyl and four propionic acid side chains attached to the pyrrole rings. Elevated levels of Coproporphyrin III in the urine and feces are major findings in patients with HEREDITARY COPROPORPHYRIA.
An enzyme that catalyzes the oxidative decarboxylation of coproporphyrinogen III to protoporphyrinogen IX by the conversion of two propionate groups to two vinyl groups. It is the sixth enzyme in the 8-enzyme biosynthetic pathway of HEME, and is encoded by CPO gene. Mutations of CPO gene result in HEREDITARY COPROPORPHYRIA.
A group of metabolic diseases due to deficiency of one of a number of LIVER enzymes in the biosynthetic pathway of HEME. They are characterized by the accumulation and increased excretion of PORPHYRINS or its precursors. Clinical features include neurological symptoms (PORPHYRIA, ACUTE INTERMITTENT), cutaneous lesions due to photosensitivity (PORPHYRIA CUTANEA TARDA), or both (HEREDITARY COPROPORPHYRIA). Hepatic porphyrias can be hereditary or acquired as a result of toxicity to the hepatic tissues.
A diverse group of metabolic diseases characterized by errors in the biosynthetic pathway of HEME in the LIVER, the BONE MARROW, or both. They are classified by the deficiency of specific enzymes, the tissue site of enzyme defect, or the clinical features that include neurological (acute) or cutaneous (skin lesions). Porphyrias can be hereditary or acquired as a result of toxicity to the hepatic or erythropoietic marrow tissues.
Colorless reduced precursors of porphyrins in which the pyrrole rings are linked by methylene (-CH2-) bridges.
A group of compounds containing the porphin structure, four pyrrole rings connected by methine bridges in a cyclic configuration to which a variety of side chains are attached. The nature of the side chain is indicated by a prefix, as uroporphyrin, hematoporphyrin, etc. The porphyrins, in combination with iron, form the heme component in biologically significant compounds such as hemoglobin and myoglobin.

Mutations in human CPO gene predict clinical expression of either hepatic hereditary coproporphyria or erythropoietic harderoporphyria. (1/6)

Hereditary coproporphyria (HCP), an autosomal dominant acute hepatic porphyria, results from mutations in the gene that encodes coproporphyrinogen III oxidase (CPO). HCP (heterozygous or rarely homozygous) patients present with an acute neurovisceral crisis, sometimes associated with skin lesions. Four patients (two families) have been reported with a clinically distinct variant form of HCP. In such patients, the presence of a specific mutation (K404E) on both alleles or associated with a null allele, produces a unifying syndrome in which hematological disorders predominate: 'harderoporphyria'. Here, we report the fifth case (from a third family) with harderoporphyria. In addition, we show that harderoporphyric patients exhibit iron overload secondary to dyserythropoiesis. To investigate the molecular basis of this peculiar phenotype, we first studied the secondary structure of the human CPO by a predictive method, the hydrophobic cluster analysis (HCA) which allowed us to focus on a region of the enzyme. We then expressed mutant enzymes for each amino acid of the region of interest, as well as all missense mutations reported so far in HCP patients and evaluated the amount of harderoporphyrin in each mutant. Our results strongly suggest that only a few missense mutations, restricted to five amino acids encoded by exon 6, may accumulate significant amounts of harderoporphyrin: D400-K404. Moreover, all other type of mutations or missense mutations mapped elsewhere throughout the CPO gene, lead to coproporphyrin accumulation and subsequently typical HCP. Our findings, reinforced by recent crystallographic results of yeast CPO, shed new light on the genetic predisposition to HCP. It represents a first monogenic metabolic disorder where clinical expression of overt disease is dependent upon the location and type of mutation, resulting either in acute hepatic or in erythropoietic porphyria.  (+info)

Structural basis of hereditary coproporphyria. (2/6)

Hereditary coproporphyria is an autosomal dominant disorder resulting from the half-normal activity of coproporphyrinogen oxidase (CPO), a mitochondrial enzyme catalyzing the antepenultimate step in heme biosynthesis. The mechanism by which CPO catalyzes oxidative decarboxylation, in an extraordinary metal- and cofactor-independent manner, is poorly understood. Here, we report the crystal structure of human CPO at 1.58-A resolution. The structure reveals a previously uncharacterized tertiary topology comprising an unusually flat seven-stranded beta-sheet sandwiched by alpha-helices. In the biologically active dimer (K(D) = 5 x 10(-7) M), one monomer rotates relative to the second by approximately 40 degrees to create an intersubunit interface in close proximity to two independent enzymatic sites. The unexpected finding of citrate at the active site allows us to assign Ser-244, His-258, Asn-260, Arg-262, Asp-282, and Arg-332 as residues mediating substrate recognition and decarboxylation. We favor a mechanism in which oxygen serves as the immediate electron acceptor, and a substrate radical or a carbanion with substantial radical character participates in catalysis. Although several mutations in the CPO gene have been described, the molecular basis for how these alterations diminish enzyme activity is unknown. We show that deletion of residues (392-418) encoded by exon six disrupts dimerization. Conversely, harderoporphyria-causing K404E mutation precludes a type I beta-turn from retaining the substrate for the second decarboxylation cycle. Together, these findings resolve several questions regarding CPO catalysis and provide insights into hereditary coproporphyria.  (+info)

Neurovisceral porphyrias: what a hematologist needs to know. (3/6)

The acute or inducible hepatic porphyrias comprise four inherited disorders of heme biosynthesis. They usually remain asymptomatic for most of the lifespan of individuals who inherit the specific enzyme deficiencies but may cause life-threatening attacks of neurovisceral symptoms. Failure to consider the diagnosis frequently delays effective treatment, and inappropriate diagnostic tests and/or mistaken interpretation of results may lead to misdiagnosis and inappropriate treatment. The four disorders are ALA dehydratase deficiency porphyria, acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria. Other conditions that clinically and biochemically may mimic acute porphyria include lead poisoning and hereditary tyrosinemia type I. The diagnosis of one of these acute porphyric syndromes should be considered in many patients with otherwise unexplained abdominal pain, severe constipation, systemic arterial hypertension, or other characteristic symptoms. Critical to the rapid diagnosis of the three most common of these disorders is demonstration of markedly increased urinary porphobilinogen (PBG) in a single-void urine specimen. The treatment of choice for all but mild attacks of the acute porphyrias is intravenous hemin therapy, which should be started as soon as possible. Intravenous glucose alone is recommended only for mild attacks (no weakness or hyponatremia) or until hemin is available.  (+info)

Lamotrigine in the treatment of psychotic depression associated with hereditary coproporphyria -- case report and a brief review of the literature. (6/6)

OBJECTIVE: We report a successful treatment with lamotrigine of a patient with hereditary coproporphyria presenting with affective and psychotic symptoms. CASE REPORT: M.F., a 38-year-old, single woman was admitted to an acute psychiatric ward because of suddenly emerging psychosis. Ms F's hereditary coproporphyria was diagnosed 9 years before the current admission. While on treatment with olanzapine (20mg/day) the psychotic symptoms have gradually disappeared. In view of her significant mood fluctuations predominantly with depressed phases, lamotrigine was started and titrated up to 125 mg/day. Ms F's mood gradually became euthymic, suicidal ideations and anxiety disappeared. At 5-month follow-up, while still on lamotrigine, her porphyria was asymptomatic. CONCLUSION: To the best of our knowledge, this is the first report about the safe administration of lamotrigine in hereditary coproporphyria. Lamotrigine did not trigger an acute porphyric attack as confirmed by clinical and laboratory findings.  (+info)

1. Urinary 17-oxosteroid conjugates were measured by gas-liquid chromatography in five patients with hereditary coproporphyria.. 2. Three patients were in an acute attack and showed significantly increased excretion of sulphate or glucuronide conjugates of aetiocholanolone. There was increased excretion of several other related steroids but no consistent pattern was apparent.. 3. In the two patients in remission, excretion of urinary 17-oxosteroids was not increased.. 4. The ratio of total urinary aetiocholanolone to androsterone (5β:5α) was found to be significantly elevated for the three patients in an acute attack. Serial measurements were made in two of these patients and showed a highly significant linear correlation between this ratio and the urinary content of δ-aminolaevulic acid and porphobilinogen.. 5. These observations suggest the involvement of the 17-oxosteroids, especially aetiocholanolone, in the pathogenesis of hereditary coproporphyria. ...
Hereditary coproporphyria is an autosomal dominant form of liver (hepatic) porphyria that is very similar to acute intermittent porphyria, although it is usually a less severe disease. It results from low levels of the enzyme responsible for the sixth step in heme production - coproporphyrinogen oxidase. This enzyme speeds the conversion of coproporphyrinogen to protoporphyrinogen. In coproporphyria, the porphyrin precursors porphobilinogen and amino-levulinic acid (ALA) accumulate, as well as the formed porphyrin coproporphyrin. This leads to abdominal pain, neuropathies, constipation, and skin changes. Treatment is dependent on the symptoms ...
Hereditary coproporphyria is one of the porphyrias, a group of diseases that involves defects in heme metabolism and that results in excessive secretion of porphyrins and porphyrin precursors. Inheritance is autosomal (usually autosomal dominant, but sometimes autosomal recessive).

Most types are inherited but the most common type, porphyria cutanea tarda is acquired, associated with liver disease and iron overload. Of 4 types, any may present with neurovisceral presentation esp colicky abdominal pain, and hereditary coproporphyria and variegate porphyria can also present with cutaneous features. Attacks are likely precipitated by adverse effects of excess ALA which is structurally similar to GABA. Starvation, poor CH2O/ energy intake, drugs, alcohol, smoking, infections and stress can ppt. In this case the negative energy balance with surgery caused up regulation of hepatic ALA synthase 1, due to loss of CH2O repression of rate controlling enzyme for heme synthesis in the liver. Other bad drugs in this case were phenytoin, tramadol and bactrim. Sulfonamides and barbiturates are also bad. So is progesterone (which is why postpubertal women are more susceptible). The treatment is i-v heme. It can prevent reversible axonal death. Prognosis is slow and incomplete ...
PBGU : First-order test for evaluation of a suspected acute porphyria: acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria
Conclusions Segregation analysis indicated three possible digenic segregation models: (i) autosomal inheritance with mutations on different chromosomes, resembling recessive inheritance (five families); (ii) autosomal inheritance with mutations on the same chromosome resembling dominant inheritance (two families) and (iii) unlinked autosomal and X-linked inheritance having a peculiar segregation (four families). This pedigree analysis provides evidence for digenic inheritance of Alport syndrome. Clinical geneticists and nephrologists should be aware of this possibility in order to more accurately assess inheritance probabilities, predict prognosis and identify other family members at risk.. ...
The acute hepatic porphyrias (AHP), including acute intermittent porphyria (AIP), hereditary coproporphyria (HCP), and variegate porphyria (VP), are due to a deficiency in the liver of one of the eight enzymes required for heme biosynthesis. Induction of the first enzyme 5-aminolevulinic acid synthase 1 (ALAS1) by triggers such as fasting or drug exposure can lead to accumulation of neurotoxic heme intermediates that result in acute life threatening neurovisceral attacks. Methods: We are currently performing a prospective, multinational, observational study to characterize the natural history and clinical management of patients with AHP who experience recurrent attacks (, 3 attacks per year) or receive prophylactic treatment to prevent attacks. Patient porphyria disease activity questionnaires, physical examinations, plasma and urinary porphyrin precursors, circulating ALAS1 mRNA and health care utilization data are collected at pre-specified intervals throughout the 6 month study. In addition, ...

FQPPS : Evaluation of patients who present with signs or symptoms suggestive of porphyria cutanea tarda, hereditary coproporphyria, variegate porphyria, congenital erythropoietic porphyria, erythropoietic protoporphyria, or X-linked dominant protoporphyria
Abstract: : Purpose: Define the role of MYOC, CYP1B1 and PITX2 in patients with juvenile open angle glaucoma. Methods: We undertook mutational analysis of three glaucoma-related genes (MYOC, CYP1B1 and PITX2)using a combination of single strand conformation polymorphism (SSCP), and direct cycle sequencing. The patient population included 60 unrelated cases affected with JOAG or early onset glaucoma (onset age 5-40 years). Results: MYOC mutations were identified in 8/60 individuals (13.3%); CYP1B1 mutations in 3/60 (5%) and none in PITX2. Individuals with MYOC mutations showed greater phenotypic variability than expected, and included pigment dispersion syndrome and a mixed-mechanism glaucoma. Mutations in CYP1B1 were identified in three cases that did not have features suggestive of congenital glaucoma. Study of one large pedigree with autosomal dominant glaucoma demonstrated segregation of both MYOC and CYP1B1 mutations with the disease. Those who carried the MYOC mutation alone had an average ...
