Abstract
Congenital erythropoietic porphyria (CEP) is a rare autosomal recessive disease due to the deficient, but not absent, activity of uroporphyrinogen III synthase (UROS), the fourth enzyme in the heme biosynthesis pathway. Biallelic variants in the UROS gene result in decreased UROS enzymatic activity and the accumulation of non-physiologic Type I porphyrins in cells and fluids. Overproduced uroporphyrins in haematopoietic cells are released into the circulation and distributed to tissues, inducing primarily hematologic and dermatologic symptoms. The clinical manifestations vary in severity ranging from non-immune hydrops fetalis in utero to mild dermatologic manifestations in adults. Here, the biochemical, molecular and clinical features of CEP as well as current and new treatment options, including the rescue of UROS enzyme activity by chaperones, are presented.

Abstract
Congenital erythropoietic porphyria (CEP) is a rare disease characterized by erosive photosensitivity and chronic hemolysis due to a defect of the enzyme uroporphyrinogen-III-synthase (UROS). To date, hematopoietic stem cell transplantation (HSCT) is the only curative therapy for the devastating early and severe form of the disease. We describe 6 patients with CEP treated with HSCT (3 of them twice after failure of a first graft) between 1994 and 2016 in our center, including 2 of the very first living patients treated more than 20 years ago. Four patients are doing well at 6 to 25 years post-HSCT, with near-normal biochemical parameters of porphyrin metabolism without the cutaneous or hematologic features of CEP. One patient died within the first year after HSCT from severe graft-versus-host disease (GVHD), and 1 child died of unexplained acute hepatic failure at 1 year after HSCT, despite full donor chimerism. Retrospectively, it appears that all but 1 child had increased transaminase activity with onset from the early postnatal period, which was significantly more marked in the child who died of liver failure. In contrast, liver function values progressively normalized after engraftment in all other children. Liver pathology before HSCT for 3 patients revealed varying degrees of portal, centrilobular, and perisinusoidal fibrosis; clarification of hepatocytes; and cytosolic porphyrin deposits. The liver porphyrin content in biopsy specimens was >60 times the normal values. Despite difficult engraftment, the long-term efficacy of HSCT in CEP appears to be favorable and reinforces its benefits for the severe form of CEP. Hepatic involvement requires careful evaluation before and after HSCT and further investigation into its pathophysiology and care.

Abstract
Congenital erythropoietic porphyria (CEP) is a rare autosomal recessive disorder characterized by photosensitivity and by hematologic abnormalities in affected individuals. CEP is caused by mutations in the uroporphyrinogen synthase (UROS) gene. In three reported cases, CEP has been associated with a specific X-linked GATA1 mutation. Disease-causing mutations in either gene result in absent or markedly reduced UROS enzymatic activity. This in turn leads to the accumulation of the non-physiologic and photoreactive porphyrinogens, uroporphyrinogen I and coproporphyrinogen I, which damage erythrocytes and elicit a phototoxic reaction upon light exposure. The clinical spectrum of CEP depends on the level of residual UROS activity, which is determined by the underlying pathogenic loss-of-function UROS mutations. Disease severity ranges from non-immune hydrops fetalis in utero to late-onset disease with only mild cutaneous involvement. The clinical characteristics of CEP include exquisite photosensitivity to visible light resulting in bullous vesicular lesions which, when infected lead to progressive photomutilation of sun-exposed areas such as the face and hands. In addition, patients have erythrodontia (brownish discoloration of teeth) and can develop corneal scarring. Chronic transfusion-dependent hemolytic anemia is common and leads to bone marrow hyperplasia, which further increases porphyrin production. Management of CEP consists of strict avoidance of exposure to visible light with sun-protective clothing, sunglasses, and car and home window filters. Adequate care of ruptured vesicles and use of topical antibiotics is indicated to prevent superinfections and osteolysis. In patients with symptomatic hemolytic anemia, frequent erythrocyte cell transfusions may be necessary to suppress hematopoiesis and decrease marrow production of the phototoxic porphyrins. In severe transfection-dependent cases, bone marrow or hematopoietic stem cell transplantation has been performed, which is curative. Therapeutic approaches including gene therapy, proteasome inhibition, and pharmacologic chaperones are under investigation.

Abstract
The porphyrias are a group of disorders characterized by defects in the heme biosynthesis pathway. Many present with skin findings including photosensitivity, bullae, hypertrichosis, and scarring. Systemic symptoms may include abdominal pain, neuropsychiatric changes, anemia, and liver disease. With advances in DNA analysis, researchers are discovering the underlying genetic causes of the porphyrias, enabling family members to be tested for genetic mutations. Here we present a comprehensive review of porphyria focusing on those with cutaneous manifestations. In Part I, we have included the epidemiology, pathogenesis, presentation, diagnosis, and histopathology. Treatment and management options will be discussed in Part II.

Abstract
Congenital erythropoietic porphyria (CEP), or Günther's disease, is an inborn error of metabolism produced by a deficiency of uroporphyrinogen III synthase (UROS), the fourth enzyme of the heme biosynthesis pathway. This enzymatic defect induces the accumulation of isomer I porphyrins in erythrocytes, skin, and tissues, producing various clinical manifestations. Severe cases are characterized by extreme photosensitivity, causing scarring and mutilations, and by hemolytic anemia, reducing life expectancy. CEP is caused by mutations in the UROS gene, and one of the most severe forms of the disease is associated with a cysteine to arginine substitution at residue 73 of the protein (C73R). CEP has been successfully treated only by the transplantation of hematopoietic precursors. We report the case of a male infant with severe postdelivery symptoms diagnosed with CEP and found to be homozygous for the C73R mutation. He underwent successful allogeneic bone marrow transplantation from a matched unrelated donor at 7 months of age. The hemolytic anemia was corrected and the porphyrin overproduction was significantly reduced. The patient remained asymptomatic after 1 year. This new case confirms that patients with severe CEP can benefit from early postnatal hematopoietic stem cell transplantation.

Abstract
BACKGROUND Congenital erythropoietic porphyria (CEP) is an autosomal recessive photomutilating porphyria with onset usually in childhood, where haematological complications determine prognosis. Due to its extreme rarity and clinical heterogeneity, management decisions in CEP are often difficult. OBJECTIVES To develop a management algorithm for patients with CEP based on data from carefully characterized historical cases. METHODS A single investigator collated data related to treatments and their outcomes in 29 patients with CEP from the U.K., France, Germany and Switzerland. RESULTS Six children were treated with bone marrow transplantation (BMT); five have remained symptomatically cured up to 11.5 years post-transplantation. Treatments such as oral charcoal, splenectomy and chronic hypertransfusion were either of no benefit or were associated with complications and negative impact on health-related quality of life. Lack of consistent genotype-phenotype correlation meant that this could not be used to predict disease prognosis. The main poor prognostic factors were early age of disease onset and severity of haematological manifestations. CONCLUSIONS A management algorithm is proposed where every patient, irrespective of disease severity at presentation, should receive a comprehensive, multidisciplinary clinical assessment and should then be reviewed at intervals based on their predicted prognosis, and the rate of onset of complications. A BMT should be considered in those with progressive, symptomatic haemolytic anaemia and/or thrombocytopenia. Uroporphyrinogen III synthase genotypes associated with poor prognosis would additionally justify consideration for a BMT. Rigorous photoprotection of the skin and eyes from visible light is essential in all patients.

Abstract
Porphyrias are rare metabolic hereditary diseases originating from defects in specific enzymes involved in the heme biosynthesis pathway. Congenital erythropoietic porphyria (CEP) is the rarest autosomal recessive porphyria resulting from a deficiency of uroporphyrinogen III cosynthase (UROS), the fourth enzyme in heme biosynthesis. CEP leads to an excessive production and accumulation of type Ι porphyrins in bone marrow, skin and several other tissues. Clinical manifestations are presented in childhood with severe cutaneous photosensitivity, blistering, scarring and deformation of the hands and the loss of eyebrows and eyelashes. Less than 200 cases of CEP have been reported to date. Four CEP patients and their family members were studied for the first time in Iran. A missense mutation in the UROS gene was identified in this family. A, T to C change at nucleotide 34313, leading to a substitution of Leucine by Proline at codon 237, was observed in the homozygous state in these 4 patients and heterozygous state in their parents. Our data from the Iranian population emphasizes the importance of codon 237 alone, given the rarity of this disease. This fact can be taken into consideration in the mutational analysis of UROS. This work emphasizes the advantages of molecular genetic techniques as diagnostic tools for the detection of clinically asymptomatic heterozygous mutation carriers as well as CEP within families.

Abstract
Hereditary porphyrias are a group of eight metabolic disorders of the haem biosynthesis pathway that are characterised by acute neurovisceral symptoms, skin lesions, or both. Every porphyria is caused by abnormal function of a separate enzymatic step, resulting in a specific accumulation of haem precursors. Seven porphyrias are the result of a partial enzyme deficiency, and a gain of function mechanism has been characterised in a new porphyria. Acute porphyrias present with acute attacks, typically consisting of severe abdominal pain, nausea, constipation, confusion, and seizure, and can be life-threatening. Cutaneous porphyrias present with either acute painful photosensitivity or skin fragility and blisters. Rare recessive porphyrias usually manifest in early childhood with either severe cutaneous photosensitivity and chronic haemolysis or chronic neurological symptoms with or without photosensitivity. Porphyrias are still underdiagnosed, but when they are suspected, and dependent on clinical presentation, simple first-line tests can be used to establish the diagnosis in all symptomatic patients. Diagnosis is essential to enable specific treatments to be started as soon as possible. Screening of families to identify presymptomatic carriers is crucial to decrease risk of overt disease of acute porphyrias through counselling about avoidance of potential precipitants.

Abstract
Stem cell transplantation (SCT) can be used to cure or ameliorate a wide variety of non-malignant diseases. These range from inherent defects of haemopoietic cell production or function, through metabolic diseases (where blood cells are providing in vivo enzyme therapy to solid organs), to severe autoimmune diseases. However, although transplantation has revolutionized the treatment of many of the diseases discussed, severe toxicities remain. In some cases these are inherent to the disease concerned but frequently they relate to the conditioning regime or post-transplant complications such as graft-versus-host disease (GvHD). This chapter concentrates on the indications for transplant, outcome statistics and problems inherent in particular conditions, seen in the light of technological improvements during the 1990s and the potential impact of enzyme and gene therapies.
