Anemia, Sideroblastic
Anemia characterized by the presence of erythroblasts containing excessive deposits of iron in the marrow.
5-Aminolevulinate Synthetase
An enzyme of the transferase class that catalyzes condensation of the succinyl group from succinyl coenzyme A with glycine to form delta-aminolevulinate. It is a pyridoxyal phosphate protein and the reaction occurs in mitochondria as the first step of the heme biosynthetic pathway. The enzyme is a key regulatory enzyme in heme biosynthesis. In liver feedback is inhibited by heme. EC 2.3.1.37.
Anemia
A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.
Anemia, Refractory
A severe sometimes chronic anemia, usually macrocytic in type, that does not respond to ordinary antianemic therapy.
Genetic Diseases, X-Linked
Genetic diseases that are linked to gene mutations on the X CHROMOSOME in humans (X CHROMOSOME, HUMAN) or the X CHROMOSOME in other species. Included here are animal models of human X-linked diseases.
Pyridoxine
The 4-methanol form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990).
Mitochondrial Myopathies
A group of muscle diseases associated with abnormal mitochondria function.
Anemia, Aplastic
A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.
Erythroblasts
Immature, nucleated ERYTHROCYTES occupying the stage of ERYTHROPOIESIS that follows formation of ERYTHROID PRECURSOR CELLS and precedes formation of RETICULOCYTES. The normal series is called normoblasts. Cells called MEGALOBLASTS are a pathologic series of erythroblasts.
Anemia, Refractory, with Excess of Blasts
Chronic refractory anemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells.
X Chromosome
The female sex chromosome, being the differential sex chromosome carried by half the male gametes and all female gametes in human and other male-heterogametic species.
Acidosis, Lactic
Acidosis caused by accumulation of lactic acid more rapidly than it can be metabolized. It may occur spontaneously or in association with diseases such as DIABETES MELLITUS; LEUKEMIA; or LIVER FAILURE.
Glutaredoxins
A family of thioltransferases that contain two active site CYSTEINE residues, which either form a disulfide (oxidized form) or a dithiol (reduced form). They function as an electron carrier in the GLUTHIONE-dependent synthesis of deoxyribonucleotides by RIBONUCLEOTIDE REDUCTASES and may play a role in the deglutathionylation of protein thiols. The oxidized forms of glutaredoxins are directly reduced by the GLUTATHIONE.
Anemia, Hemolytic
A condition of inadequate circulating red blood cells (ANEMIA) or insufficient HEMOGLOBIN due to premature destruction of red blood cells (ERYTHROCYTES).
Preleukemia
Conditions in which the abnormalities in the peripheral blood or bone marrow represent the early manifestations of acute leukemia, but in which the changes are not of sufficient magnitude or specificity to permit a diagnosis of acute leukemia by the usual clinical criteria.
Iron
A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.
Hydro-Lyases
Enzymes that catalyze the breakage of a carbon-oxygen bond leading to unsaturated products via the removal of water. EC 4.2.1.
Fanconi Anemia
Congenital disorder affecting all bone marrow elements, resulting in ANEMIA; LEUKOPENIA; and THROMBOPENIA, and associated with cardiac, renal, and limb malformations as well as dermal pigmentary changes. Spontaneous CHROMOSOME BREAKAGE is a feature of this disease along with predisposition to LEUKEMIA. There are at least 7 complementation groups in Fanconi anemia: FANCA, FANCB, FANCC, FANCD1, FANCD2, FANCE, FANCF, FANCG, and FANCL. (from Online Mendelian Inheritance in Man, http://www.ncbi.nlm.nih.gov/entrez/dispomim.cgi?id=227650, August 20, 2004)
Ataxia
Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharynx, larynx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.
Bone Marrow
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
Anemia, Hemolytic, Autoimmune
Acquired hemolytic anemia due to the presence of AUTOANTIBODIES which agglutinate or lyse the patient's own RED BLOOD CELLS.
Anemia, Hypochromic
Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)
Genes, X-Linked
Genes that are located on the X CHROMOSOME.
Pedigree
The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.
Pyridoxal Phosphate
This is the active form of VITAMIN B 6 serving as a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into pyridoxamine phosphate (PYRIDOXAMINE).
Anemia, Macrocytic
Anemia characterized by larger than normal erythrocytes, increased mean corpuscular volume (MCV) and increased mean corpuscular hemoglobin (MCH).
Anemia, Pernicious
A megaloblastic anemia occurring in children but more commonly in later life, characterized by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin B 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (Dorland, 27th ed)
Heme
The color-furnishing portion of hemoglobin. It is found free in tissues and as the prosthetic group in many hemeproteins.
Blood Transfusion
The introduction of whole blood or blood component directly into the blood stream. (Dorland, 27th ed)
Erythropoiesis
The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction.
Anemia, Sickle Cell
A disease characterized by chronic hemolytic anemia, episodic painful crises, and pathologic involvement of many organs. It is the clinical expression of homozygosity for hemoglobin S.
Genetic Linkage
The co-inheritance of two or more non-allelic GENES due to their being located more or less closely on the same CHROMOSOME.

Four new mutations in the erythroid-specific 5-aminolevulinate synthase (ALAS2) gene causing X-linked sideroblastic anemia: increased pyridoxine responsiveness after removal of iron overload by phlebotomy and coinheritance of hereditary hemochromatosis. (1/161)

X-linked sideroblastic anemia (XLSA) in four unrelated male probands was caused by missense mutations in the erythroid-specific 5-aminolevulinate synthase gene (ALAS2). All were new mutations: T647C, C1283T, G1395A, and C1406T predicting amino acid substitutions Y199H, R411C, R448Q, and R452C. All probands were clinically pyridoxine-responsive. The mutation Y199H was shown to be the first de novo XLSA mutation and occurred in a gamete of the proband's maternal grandfather. There was a significantly higher frequency of coinheritance of the hereditary hemochromatosis (HH) HFE mutant allele C282Y in 18 unrelated XLSA hemizygotes than found in the normal population, indicating a role for coinheritance of HFE alleles in the expression of this disorder. One proband (Y199H) with severe and early iron loading coinherited HH as a C282Y homozygote. The clinical and hematologic histories of two XLSA probands suggest that iron overload suppresses pyridoxine responsiveness. Notably, reversal of the iron overload in the Y199H proband by phlebotomy resulted in higher hemoglobin concentrations during pyridoxine supplementation. The proband with the R452C mutation was symptom-free on occasional phlebotomy and daily pyridoxine. These studies indicate the value of combined phlebotomy and pyridoxine supplementation in the management of XLSA probands in order to prevent a downward spiral of iron toxicity and refractory anemia.  (+info)

Mutation of a putative mitochondrial iron transporter gene (ABC7) in X-linked sideroblastic anemia and ataxia (XLSA/A). (2/161)

X-linked sideroblastic anemia and ataxia (XLSA/A) is a recessive disorder characterized by an infantile to early childhood onset of non-progressive cerebellar ataxia and mild anemia with hypochromia and microcytosis. A gene encoding an ATP-binding cassette (ABC) transporter was mapped to Xq13, a region previously shown by linkage analysis to harbor the XLSA/A gene. This gene, ABC7, is an ortholog of the yeast ATM1 gene whose product localizes to the mitochondrial inner membrane and is involved in iron homeostasis. The full-length ABC7 cDNA was cloned and the entire coding region screened for mutations in a kindred in which five male members manifested XLSA/A. An I400M variant was identified in a predicted transmembrane segment of the ABC7 gene in patients with XLSA/A. The mutation was shown to segregate with the disease in the family and was not detected in at least 600 chromosomes of general population controls. Introduction of the corresponding mutation into the Saccharomyces cerevisiae ATM1 gene resulted in a partial loss of function of the yeast Atm1 protein. In addition, the human wild-type ABC7 protein was able to complement ATM1 deletion in yeast. These data indicate that ABC7 is the causal gene of XLSA/A and that XLSA/A is a mitochondrial disease caused by a mutation in the nuclear genome.  (+info)

Prognostic significance of magnetic resonance imaging of femoral marrow in patients with myelodysplastic syndromes. (3/161)

PURPOSE: To investigate whether the abnormalities observed on femoral marrow magnetic resonance images are related to the development of leukemia and survival of patients with myelodysplastic syndromes (MDS). PATIENTS AND METHODS: The findings on magnetic resonance images of the femoral marrow were evaluated over periods of 1 to 92 months (median, 18 months) in 42 consecutive adult patients with newly diagnosed MDS. Magnetic resonance images were obtained by the T1-weighted spin echo method and the short T1 inversion recovery technique. RESULTS: Magnetic resonance images showed that the femoral marrow patterns changed from fatty, faint, or nodular to scattered or uniform as the disease progressed. Development of acute myeloid leukemia was observed in only 13 patients whose marrow exhibited a scattered or uniform pattern. The overall survival of the 29 patients with a scattered or uniform marrow pattern was significantly shorter than that of the 13 patients with a fatty, faint, or nodular marrow pattern (10.7% v 73.3% at 7 years; P < .01). The period of leukemia-free survival was also significantly shorter in the patients with a scattered or uniform marrow pattern versus a fatty, faint, or nodular pattern (37.7% v 100% at 7 years; P < .01). CONCLUSION: Magnetic resonance images of the femoral marrow can provide valuable information for assessing the prognosis and determining the most appropriate management of patients with MDS.  (+info)

Nonrandom chromosomal abnormalities in hematologic disorders of man. (4/161)

A nonrandom pattern of chromosomal abnormalities occurs in bone marrow cells obtained from patients with hematologic disorders who have an abnormal karyotype involving a C group chromosome. An additional number 8 chromosome is the most common abnormality, found in more than one-half of the patients studies. An additional number 9 chromosome and the loss of all or part of a number 7 are abnormalities that occur more often than might be expected by chance. It is proposed that specific human chromosomal abnormalities may be related to different specific etiologic agents.  (+info)

Mother cell of megakaryocyte. (5/161)

It was attempted to describe the morphology of the most immature cell of megakaryocytic series. The megakaryocytes were observed with the electron microscope in five cases, being traced back to their immature forms. In two cases the most immature cells of megakaryocytic series were considered to be the cells which were probably identified as lymphocytes under the light microscope, but they were not lymphocytes with the electron microscope. In other two cases it was presumed that neutrophilic and megakaryocytic series were derived from morphologically similar immature cells, since the most immature cells of neutrophilic and megakaryocytic series were not distinguished when they were traced back to their immature forms. These findings suggest that mother cells of megakaryocytes in the adult bone marrow may be identified as lymphoid cells with the light microscope.  (+info)

Mechanism of platelet liberation. (6/161)

Megakaryocytes from 5 patients and 1 normal person were observed electronmicroscopically. In some pathologic states platelets seemed to be liberated without demarcation membrane system (DMS) and in a normal individual they seemed to be liberated independently of DMS. These findings suggest that DMS is not concerned with platelet liberation and that platelets are liberated through pseudopodia and bleb formation. In mature megakaryocytes vigorous amoeboid movement seems to exist and both pseudopodia and blebs may represent this movement. Structural similarity between surface connected system (SCS) of platelet and DMS of megakaryocyte suggests that the structure called DMS is transported as SCS into platelet.  (+info)

Trisomy 8 in the bone marrow associated with high red cell glutathione reductase activity. (7/161)

In a series of 841 patients with hematologic disorders, 10 individuals were found to have an extra C group chromosome in their bone marrow cells. In two the extra chromosome was not identified, but in the remaining eight it was No. 8. Four of these ten patients had leukemia, and the others had cytopenias or other probably preleukemic conditions. The mean value for glutathione reductase activity in the red cells of four patients with trisomy 8 was significantly higher (2980 +/- 940 mumoles/min/liter of erythrocytes) than in normal controls (1930 +/- 360) or in any of five different control groups of patients with hematologic disorders. The extent of enzyme activation as a result of preincubation with exogenous flavin adenine dinucleotide was similar in the erythrocytes of all groups. The reasons for the high values of red cell glutathione reductase activity in patients with trisomy 8 are discussed in the light of the proposed assignment of the gene for that enzyme to chromosome 8.  (+info)

Successful allogeneic bone marrow transplantation for childhood-onset refractory anemia with ringed sideroblasts. (8/161)

Refractory anemia with ringed sideroblasts (RARS) is an extremely rare type of myelodysplastic syndrome in children. We describe a 10-year-old boy with RARS presented with pancytopenia. He remained relatively stable with only a few transfusions until age of 20 years, when he underwent an allogeneic bone marrow transplantation (BMT) because of increased transfusion requirements. He remains in complete chimeric state at 20 months posttransplant with normal hematologic parameters. To our knowledge, this is the first description of successful BMT in a patient with childhood-onset RARS. The indication of BMT for this rare disorder in children is discussed.  (+info)

YARS2 variants have previously been described in patients with myopathy, lactic acidosis and sideroblastic anemia 2 (MLASA2). YARS2 encodes the mitochondrial tyrosyl-tRNA synthetase, which is responsible for conjugating tyrosine to its cognate mt-tRNA for mitochondrial protein synthesis. Here we describe 14 individuals from 11 families presenting with sideroblastic anemia and YARS2 variants that we identified using a sideroblastic anemia gene panel or exome sequencing. The phenotype of these patients ranged from MLASA to isolated congenital sideroblastic anemia. As in previous cases, inter- and intra-familial phenotypic variability was observed, however, this report includes the first cases with isolated sideroblastic anemia and patients with biallelic YARS2 variants that have no clinically ascertainable phenotype. We identified ten novel YARS2 variants and three previously reported variants. In vitro amino-acylation assays of five novel missense variants showed that three had less effect on the ...

Hereditary sideroblastic anemia
The essential features of X-linked sideroblastic anemia include the following: (1) a hypochromic microcytic anemia and 2 discrete populations of red blood cells, one microcytic and the other normocytic; (2) marrow ringed sideroblasts, particularly prominent in the late erythroid precursors; (3) a variable hematologic response to pharmacologic doses of pyridoxine; and (4) systemic iron overload secondary to chronic ineffective erythropoiesis. The age of clinical onset of the disorder can vary from in utero to the ninth decade. Whereas males are preferentially affected, females may present with clinically severe anemia. More commonly, female carriers of the disease have an increased red blood cell distribution width and sometimes erythrocyte dimorphism ({18:Fleming, 2002 ...

sideroblastic anemiasideroblastic anemia
A decade ago, Brooks McMurrays routine check-up was anything but routine. The suburban Boston boys spleen was enlarged. His red blood cell count was low and the cells were very small and very pale, which suggested a serious iron deficiency anemia. The family pediatrician referred McMurray, now a 19-year-old college freshman, to Dana-Farber/Boston Childrens Cancer and Blood Disorders Center.. There hematologists discovered the boy had unexpectedly high iron levels. Together with pathologist Mark Fleming, MD, DPhil, they solved the mystery. McMurray has congenital sideroblastic anemia, an inherited blood disorder so rare that fewer than 1,000 cases have been reported worldwide. Iron was getting stuck in the wrong place in the precursor red blood cells developing in his bone marrow. …. ...

The activity of 5-aminolaevulinate (ALA) synthase, the first and rate-limiting of haem synthesis, was markedly reduced (13% of controls) in erythroblasts of a patient with acquired, primary sideroblastic anaemia (PASA). The reduced activity of ALA synthase could not be restored in vitro with 1 mmol/l pyridoxal-5-phosphate (PLP). Treatment of the patient with pyridoxine for several months increased the ALA synthase activity from 13% to 50% of controls in the absence and to 100% in the presence of PLP in the incubation medium. These studies suggest that both increased degradation of apo-ALA synthase and decreased affinity of ALA synthase for PLP may be involved in pyridoxine-responsive PASA ...

Erythropoietic porphyria - WikipediaErythropoietic porphyria - Wikipedia
X-linked sideroblastic anemia or X-linked dominant erythropoietic protoporphyria, associated with ALAS2 (aminolevulinic acid synthase), has also been described. X-linked dominant erythropoietic protoporphyria (XDEPP) is caused by a gain of function mutation in the ALAS2 (5-aminolevulinate synthase) gene; that gene encodes the very first enzyme in the heme biosynthetic pathway. The mutation is caused by a frameshift mutation caused by one of two deletions in the ALAS2 exon 11, either c. 1706-1709 delAGTG or c. 1699-1700 delAT. This alters the 19th and 20th residues of the C-terminal domain thereby altering the secondary structure of the enzyme. The delAT mutation only occurred in one family studied whereas the delAGTG mutation occurred in several genetically distinct families. The delAGTG causes a loss of an α-helix which is replaced by a β-sheet. Previously known mutations in the ALAS2 resulted in a loss-of-function mutation causing X-linked sideroblastic anemia. Erythropoietic ...

The pathophysiology of myelodysplasia is complex. There is evidence for impairments in stem cell growth, progenitor maturation, and both growth factor production and progenitor responsiveness. The presence of ineffective hematopoiesis (increased apoptosis of maturing marrow precursors) is a hallmark of myelodysplasia. It appears to correlate in part with CD95 expression and persistent high levels of Fas receptor, resulting in increased fas-ligand apoptosis. Upregulation of the cytokines tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) also may play a role in promoting apoptosis of long-term hematopoietic stem cells (LT-HSC) and committed precursors in myelodysplastic marrows. Vascular endothelial growth factor (VEGF) overproduction is thought to be involved in the promotion of myeloblastic elements, and perhaps the evolution to acute myeloid leukemia (AML). ...

Anemia idiopathic affects the body from the formation of blood cells in the process of coagulation. These related anemia diseases called idiopathic received this name due to its unknown origin, types of anemia idiopathic damage or destroy the stem cells which are then converted into red blood cells, as the case of aplastic anemia is idiopathic or idiopathic Myelofibrosis. Sideroblastic anemia makes the body unable to transform iron into hemoglobin, and idiopathic thrombocytopenia is the lack of an adequate number of platelets. Idiopathic diseases are not only limited to the blood, also can affect other regions of the body. Idiopathic, or hypoplasia aplastic anemia, is anemia that usually occurs when the bone marrow stem cells are injured or damaged. Less often, this type of idiopathic anemia occurs as result of damage to the vasculature of the bone marrow itself, therefore, inhibits the growth and the maturity of the red and white blood cells, along with platelets.

Activation of apoptosis in NAF-1-deficient human epithelial breast cancer cells | Journal of Cell ScienceActivation of apoptosis in NAF-1-deficient human epithelial breast cancer cells | Journal of Cell Science
Previous studies have suggested that NAF-1 could be involved in maintaining Fe ion homeostasis in cells (Sohn et al., 2013; Tamir et al., 2015). Nevertheless, the precise role of NAF-1 in this process has remained unclear. Here, we show that NAF-1 deficiency results in an increased expression of TfR at the plasma membrane, an increased uptake of transferrin-bound Fe into cells and an increased production of ROS in the mitochondria (Figs 3, 4; Figs S1, S2). Taken together, the alterations in Fe ions and ROS in cancer cells with suppressed NAF-1 expression appear to resemble the alterations in Fe ions and ROS that are induced by the disruption of Fe-S biogenesis in conditions such as Friedreichs ataxia and in some forms of sideroblastic anemia (Napier et al., 2005; Wilson, 2006). NAF-1 could therefore be required for proper Fe-S biogenesis or mobilization in cancer cells. In support of such a possibility are the unique properties of the NAF-1-containing Fe-S cluster, namely that it is labile and ...

ALAS2 gene - Genetics Home Reference - NIHALAS2 gene - Genetics Home Reference - NIH
At least 50 mutations that cause X-linked sideroblastic anemia have been identified in the ALAS2 gene. Almost all of these mutations change single protein building blocks (amino acids) in erythroid ALA-synthase. These changes impair the activity of the enzyme, which disrupts the normal production of heme in developing red blood cells. A reduction in the amount of heme prevents these cells from making enough hemoglobin. Because almost all of the iron transported into erythroblasts is normally incorporated into heme, the reduced production of heme leads to a buildup of excess iron in these cells. Additionally, the body attempts to compensate for the hemoglobin shortage by absorbing more iron from the diet. This buildup of excess iron can damage the bodys organs. Low hemoglobin levels and the resulting accumulation of iron in the bodys organs lead to the characteristic features of X-linked sideroblastic anemia. ...

Pearson syndrome - WikipediaPearson syndrome - Wikipedia
Pearson syndrome is a mitochondrial disease characterized by sideroblastic anemia and exocrine pancreas dysfunction. Other clinical features are failure to thrive, pancreatic fibrosis with insulin-dependent diabetes and exocrine pancreatic deficiency, muscle and neurologic impairment, and, frequently, early death. It is usually fatal in infancy. The few patients who survive into adulthood often develop symptoms of Kearns-Sayre syndrome. It is caused by a deletion in mitochondrial DNA. Pearson syndrome is very rare, less than hundred cases have been reported in medical literature worldwide. The syndrome was first described by pediatric hematologist and oncologist Howard Pearson in 1979; the deletions causing it were discovered a decade later. Pearson Syndrome is a very rare mitochondrial disorder that is characterized by health conditions such as sideroblastic anemia, liver disease, and exocrine pancreas deficiency. Pearson Syndrome is a mitochondrial disease caused by a deletion in mitochondrial ...

Somatic SF3B1 mutation in myelodysplasia with ring sideroblasts. - Immunology
BACKGROUND: Myelodysplastic syndromes are a diverse and common group of chronic hematologic cancers. The identification of new genetic lesions could facilitate new diagnostic and therapeutic strategies. METHODS: We used massively parallel sequencing technology to identify somatically acquired point mutations across all protein-coding exons in the genome in 9 patients with low-grade myelodysplasia. Targeted resequencing of the gene encoding RNA splicing factor 3B, subunit 1 (SF3B1), was also performed in a cohort of 2087 patients with myeloid or other cancers. RESULTS: We identified 64 point mutations in the 9 patients. Recurrent somatically acquired mutations were identified in SF3B1. Follow-up revealed SF3B1 mutations in 72 of 354 patients (20%) with myelodysplastic syndromes, with particularly high frequency among patients whose disease was characterized by ring sideroblasts (53 of 82 [65%]). The gene was also mutated in 1 to 5% of patients with a variety of other tumor types. The observed mutations

Anemia - Cancer Therapy AdvisorAnemia - Cancer Therapy Advisor
The third step in working up an anemia is to assess red cell size (i.e., volume - the mean corpuscular volume [MCV], normal range ca. 80-100 femtoliters) and size distribution (the red blood cell distribution width [RDW], a measure of circulating red cell size variability, attempts to quantitate the older descriptor for size heterogeneity:anisocytosis). An abnormal MCV can be very helpful in narrowing the likely source of anemia. Conversely, a normal MCV cannot be taken to rule out those sources typically associated with microcytosis (MCV, 80) or macrocytosis (MCV,100).. Microcytic anemias (MCV , 80) are invariably due to defects in hemoglobin production. This occurs because of iron deficiency (by far the most common), thalassemia, sideroblastic anemias, or, uncommonly, the anemia of chronic inflammation. Thalassemia trait usually presents with profound microcytosis and mild to moderate anemia (MCV, 70, Hct, 30), in iron deficiency the MCV rarely falls below 80 until the anemia is significant ...

TRNT1 (CCA-adding transfer RNA nucleotidyl transferase) enzyme deficiency is a new metabolic disease caused by defective post-transcriptional modification of mitochondrial and cytosolic transfer RNAs (tRNAs). We investigated four patients from two families with infantile-onset cyclical, aseptic febrile episodes with vomiting and diarrhoea, global electrolyte imbalance during these episodes, sideroblastic anaemia, B lymphocyte immunodeficiency, retinitis pigmentosa, hepatosplenomegaly, exocrine pancreatic insufficiency and renal tubulopathy. Other clinical features found in children include sensorineural deafness, cerebellar atrophy, brittle hair, partial villous atrophy and nephrocalcinosis. Whole exome sequencing and bioinformatic filtering were utilised to identify recessive compound heterozygous TRNT1 mutations (missense mutation c.668T|C, p.Ile223Thr and a novel splice mutation c.342+5G|T) segregating with disease in the first family. The second family was found to have a homozygous TRNT1 mutation
