Abstract
Iron-sulfur (Fe/S) proteins are a class of ubiquitous components that assist in vital and diverse biochemical tasks in virtually every living cell. These tasks include respiration, iron homeostasis and gene expression. The past decade has led to the discovery of novel Fe/S proteins and insights into how their Fe/S cofactors are formed and incorporated into apoproteins. This review summarizes our current knowledge of mammalian Fe/S proteins, diseases related to deficiencies in these proteins and on disorders stemming from their defective biogenesis. Understanding both the physiological functions of Fe/S proteins and how Fe/S clusters are formed will undoubtedly enhance our ability to identify and treat known disorders of Fe/S cluster biogenesis and to recognize hitherto undescribed Fe/S cluster-related diseases.

Abstract
OBJECTIVE Study of the disease patterns and clinical evaluation of myelodysplastic syndrome (MDS). SUBJECTS AND METHODS A retrospective analysis was carried out on 85 patients, with MDS who were followed up over a period of 23 years at Jordan University Hospital, Amman, Jordan. Cases were analyzed according to the French, American and British Classification. RESULTS Of the 85 patients, 42 (49.4%) were females and 43 (50%) males; mean age was 59 +/- 19 years (range 18-88). Most subtypes found in patients were refractory anemia (RA) in 27 (31.8%) and RA with excess blasts (RAEB) in 28 (32.9%). Adverse prognostic indicators were RAEB subtype and requirement for blood transfusion. CONCLUSION Our findings showed that MDSs appeared at a younger age and tended to be of the aggressive subtype. Chronic myelomonocytic leukemia subtype seemed to appear dominantly in men.

Abstract
The human protein ABC7 belongs to the adenosine triphosphate-binding cassette transporter superfamily, and its yeast orthologue, Atm1p, plays a central role in the maturation of cytosolic iron-sulfur (Fe/S) cluster-containing proteins. Previously, a missense mutation in the human ABC7 gene was shown to be the defect in members of a family affected with X-linked sideroblastic anemia with cerebellar ataxia (XLSA/A). Here, the promoter region and the intron/exon structure of the human ABC7 gene were characterized, and the function of wild-type and mutant ABC7 in cytosolic Fe/S protein maturation was analyzed. The gene contains 16 exons, all with intron/exon boundaries following the AG/GT rule. A single missense mutation was found in exon 10 of the ABC7 gene in 2 affected brothers with XLSA/A. The mutation was a G-to-A transition at nucleotide 1305 of the full-length cDNA, resulting in a charge inversion caused by the substitution of lysine for glutamate at residue 433 C-terminal to the putative sixth transmembrane domain of ABC7. Expression of normal ABC7 almost fully complemented the defect in the maturation of cytosolic Fe/S proteins in a yeast strain in which the ATM1 gene had been deleted (Deltaatm1 cells). Thus, ABC7 is a functional orthologue of Atm1p. In contrast, the expression of mutated ABC7 (E433K) or Atm1p (D398K) proteins in Deltaatm1 cells led to a low efficiency of cytosolic Fe/S protein maturation. These data demonstrate that both the molecular defect in XLSA/A and the impaired maturation of a cytosolic Fe/S protein result from an ABC7 mutation in the reported family.

Abstract
OBJECTIVE Analysis of pathogenic gene linkage and hemopoietic characteristics in a kindred with sideroblastic anemia. METHODS PCR amplification of the microsatellites DXS991,DXS1199 in chromosome Xp11.22 linked gene ALAS2 and of the microsatellite DXS1226 in Xp22. 13 linked another irrelevant gene and analysis of gene linkage in a kindred with 2 patients and 7 normal persons. The bone marrow hemopoietic cells from 2 patients were cultured in condition culture matrix with various cytokines added in and the CFU-E, CFU-GM and CFU-Meg formations were observed at different times. RESULTS The kindred study revealed that pathogenic gene linked with DXS991 and DXS1199 but did not link with DXS1226.Hemopoietic cell culture showed that erythroid colonies of the two patients grew more vigorously than controls and they could grew in the absence of Epo except in common condition matrix. The erythroid colonies withered after a week and were smaller than the controls after 13 days. CONCLUSION The kindred is subject to an X-linked sideroblastic anemia(XLSA) with the pathogenic gene ALAS2 involved. In XLSA,the function of stem cells is primarily normal before erythropoiesis, then the erythroid progenitors become dysplasia.

Abstract
Sideroblastic anemia associated with vacuolization of haemopoietic precursors can be observed in some constitutional diseases associated with mitochondrial DNA deletion. In this condition, it is the haematological expression of a multi-tissue disorder. Haemopoiesis is polyclonal, without abnormality of nuclear DNA differing from the acquired idiopathic sideroblastic anemias which arise from a clonal transformed stem cell. This model of childhood polyclonal myelodysplasia can be observed in others myelodysplasias associated with constitutional polymalformative syndromes.

Abstract
Among 123 patients with ringed sideroblasts on bone marrow aspirates, 85 had acquired ringed sideroblasts with primary myelodysplasia. The patients were placed in categories modified from the French-American-British classification based on percentages of ringed sideroblasts and myeloblasts in the initial bone marrow. Overall, 48% (41/85) of patients with myelodysplasia developed acute leukemia. Primary acquired sideroblastic anemia was the most favorable category with longer survival and 13.8% (4/29) leukemic conversions. Variables correlating with leukemic transformation included male sex, thrombocytopenia, neutropenia, and pseudo-Pelger-Huët neutrophils. Only two variables had independent predictive value by multivariate regression analysis: a high percentage of myeloblasts and a low percentage of ringed sideroblasts. Numerous ringed sideroblasts strongly predicts a more favorable course in myelodysplastic patients.

Abstract
We analyzed the natural history of idiopathic refractory sideroblastic anemia (IRSA) in 37 patients studied between 1969 and 1986. Although erythroid abnormalities were prominent in all, 12 patients also showed involvement of the granulocytic and/or megakaryocytic cell lines, and nonrandom chromosomal aberrations were observed in five of 23 patients studied for such defects. Measurements of erythroid marrow function showed in most cases erythroid expansion with ineffective erythropoiesis. In seven patients, however, the erythroid activity was found to be inappropriately low for the degree of anemia. Transfusion dependence occurred in 26 of 37 cases. Iron overload was a common feature at presentation but produced clinical manifestations of hemochromatosis only in those patients who subsequently had a regular need for blood transfusions. Five patients progressed to bone marrow failure, and another five patients (two of whom had monosomy 7) evolved into acute nonlymphocytic leukemia (ANLL). The median survival was 72 months, with a high transfusion requirement, multilineage defects, and inappropriately low erythroid proliferation being associated with a poor prognosis. The most common causes of death were complications of iron overload and evolution into ANLL. We conclude that (a) the natural history of IRSA is characterized by an initial phase of erythroid hyperplasia and ineffective erythropoiesis, which is usually stable for many years but in a subset of patients may be followed by a phase of marrow failure with or without the later emergence of leukemic blasts; (b) peripheral blood counts, measurement of erythroid marrow function, and chromosomal analysis are useful for identifying subjects at risk of evolution into marrow failure or ANLL; and (c) IRSA patients with no need for blood transfusions are very likely to be long survivors, whereas those who become transfusion dependent are at risk of death from the complications of secondary hemochromatosis.

Abstract
The relationship between the level of erythropoiesis and iron balance was evaluated in 13 subjects with idiopathic refractory anemias. Serum ferritin levels and bone marrow iron stores were increased only in those patients with ring sideroblasts, erythroid hyperplasia and ineffective erythropoiesis. The magnitude of the increase correlated with the duration of anemia and the degree of increase in the erythron iron turnover. Ferritin levels were not related to the severity of the anemia, indicating that increased iron stores did not represent a shift of iron from the erythron or an absorption response to anemia per se. It does suggest that the level of erythroid proliferation directly affects gastrointestinal iron absorption, which in time leads to iron overload.
