Blackfan-Diamond anemia and dyserythropoietic anemia presenting with increased nuchal translucency at 12 weeks of gestation. (1/103)

Blackfan-Diamond anemia is a congenital hypoplastic anemia with a birth prevalence of about 1 in 200,000, usually presenting in the first few months of life and commonly associated with cardiac, urogenital and digital anomalies. Congenital dyserythropoietic anemias are a group of rare congenital anemias characterized by ineffective erythropoiesis. We report on two cases of congenital fetal anemia, one with Blackfan-Diamond anemia and one with dyserythropoietic anemia, presenting with increased nuchal translucency at 12 weeks of gestation.  (+info)

Response of Diamond-Blackfan anemia to metoclopramide: evidence for a role for prolactin in erythropoiesis. (2/103)

A 47-year-old woman with severe macrocytic anemia markedly improved during the second and third trimesters of 3 pregnancies and when breast-feeding her 2 children. Because the serum prolactin level is elevated at these times, we later treated her with metoclopramide (10 mg orally 3 times daily), a medication known to induce prolactin release. Her serum prolactin levels increased from 7 to 133 ng/mL (normal < 20 ng/mL) and hematocrit from 17% to 22% to 35%. With continued therapy (now 10 mg orally daily), her hematocrit has ranged from 30% to 40% for 6 years, although the macrocytosis persists (mean corpuscular volume, 100-112 fL). On the basis of this observation, a pilot study was undertaken of metoclopramide therapy in patients with Diamond-Blackfan anemia who were refractory to low doses of corticosteroids. Fifteen patients were enrolled and 9 completed the planned 16 weeks of therapy. Three individuals responded, suggesting that this therapeutic approach may benefit others. As with the index case, the anemia did not improve until 12 to 15 weeks of therapy had been completed.  (+info)

Gene transfer improves erythroid development in ribosomal protein S19-deficient Diamond-Blackfan anemia. (3/103)

Diamond-Blackfan anemia (DBA) is a congenital bone marrow failure syndrome characterized by a specific deficiency in erythroid progenitors. Forty percent of the patients are blood transfusion-dependent. Recent reports show that the ribosomal protein S19 (RPS19) gene is mutated in 25% of all patients with DBA. We constructed oncoretroviral vectors containing the RPS19 gene to develop gene therapy for RPS19-deficient DBA. These vectors were used to introduce the RPS19 gene into CD34(+) bone marrow (BM) cells from 4 patients with DBA with RPS19 gene mutations. Overexpression of the RPS19 transgene increased the number of erythroid colonies by almost 3-fold. High expression levels of the RPS19 transgene improved erythroid colony-forming ability substantially whereas low expression levels had no effect. Overexpression of RPS19 had no detrimental effect on granulocyte-macrophage colony formation. Therefore, these findings suggest that gene therapy for RPS19-deficient patients with DBA using viral vectors that express the RPS19 gene is feasible.  (+info)

Marrow failure. (4/103)

This chapter describes the clinical presentation and molecular basis of two inherited bone marrow failure syndromes, Fanconi anemia (FA), and Diamond-Blackfan anemia (DBA). It also provides an update on diagnostic and therapeutic approaches to bone marrow failure of all types (inherited and acquired) in pediatric patients. In Section I, Dr. Alan D'Andrea reviews the wide range of clinical manifestations of Fanconi anemia. Significant advances have been made in understanding the molecular pathogenesis of FA. On the basis of these advances, new diagnostic assays and treatment options are now available. In Section II, Dr. Niklas Dahl examines the clinical features and molecular pathogenesis of Diamond-Blackfan anemia. The possible links between the RPS19 gene (DBA gene) and the erythropoiesis defect are considered. In Section III, Drs. Eva Guinan and Akiko Shimamura provide an algorithm for the diagnostic evaluation and treatment of children with inherited or acquired aplastic anemia. Through the presentation of a case study of a pediatric patient with bone marrow failure, he provides an overview of the newest tests and treatment options.  (+info)

Nucleolar localization of RPS19 protein in normal cells and mislocalization due to mutations in the nucleolar localization signals in 2 Diamond-Blackfan anemia patients: potential insights into pathophysiology. (5/103)

Ribosomal protein S19 (RPS19) is frequently mutated in Diamond-Blackfan anemia (DBA), a rare congenital hypoplastic anemia. Recent studies have shown that RPS19 expression decreases during terminal erythroid differentiation. Currently no information is available on the subcellular localization of normal RPS19 and the potential effects of various RPS19 mutations on cellular localization. In the present study, using wild-type and mutant RPS19 cDNA, we explored the subcellular distribution of normal and mutant proteins in a fibroblast cell line (Cos-7 cells). RPS19 was detected primarily in the nucleus, and more specifically in the nucleoli, where RPS19 colocalized with the nucleolar protein nucleolin. Using various N-terminal and C-terminal deletion constructs, we identified 2 nucleolar localization signals (NoSs) in RPS19: the first comprising amino acids Met1 to Arg16 in the NH2-terminus and the second comprising Gly120 to Asn142 in the COOH-terminus. Importantly, 2 mutations identified in DBA patients, Val15Phe and Gly127Gln, each of which localized to 1 of the 2 NoS, failed to localize RPS19 to the nucleolus. In addition to their mislocalization, there was a dramatic decrease in the expression of the 2 mutant proteins compared to the wild type. This decrease in protein expression was specific for the mutant RPS19, since expression of other proteins was normal. The present findings enable us to document the nucleolar localization signals in RPS19 and help define the phenotypic consequences of some mutations in RPS19 in DBA.  (+info)

Molecular basis of Diamond-Blackfan anemia: new findings from the Italian registry and a review of the literature. (7/103)

BACKGROUND AND OBJECTIVES: Diamond-Blackfan anemia (DBA) is a rare, pure red blood cell aplasia of childhood caused by an intrinsic defect in erythropoietic progenitors. Malformations occur in about 40% of patients. More than half of patients respond to steroids; non-responders need chronic transfusions or stem cell transplantation (SCT). Mutations in the gene encoding ribosomal protein S19 are found in 25% of patients, but the link with erythropoiesis is unclear. A second DBA locus has been found on chromosome 8p22-p23; analysis of genes of the region is in progress. METHODS AND INFORMATION SOURCES: We present clinical and molecular data from 97 Italian DBA patients and a review of the literature. RESULTS AND STATE OF THE ART: We describe five new RPS19 gene mutations: four point mutations and one unbalanced chromosomal translocation. Hematologic findings, malformations and outcome are similar in the RPS19 mutated and the non-mutated groups. No genotype-phenotype correlation has been found so far in RPS19 mutated patients. Our data, however, and a thorough review of literature show a worse outcome (expressed as transfusion dependence) in patients with mutations that completely abolish one allele, i.e. gross chromosomal rearrangements and mutations at the initiation codon. The association of mental retardation with large deletions at the 19q locus points to a contiguous gene syndrome. A recurrent missense mutation (Arg62Trp) is associated with transfusion dependence in eight of the nine reported cases. PERSPECTIVES: Nationwide collaboration and population-based registries recording molecular data are essential for the further dissection of this rare heterogeneous disease and the definition of new therapeutic trials.  (+info)

Targeted disruption of the ribosomal protein S19 gene is lethal prior to implantation. (8/103)

The ribosomal protein S19 (RPS19) is located in the small (40S) subunit and is one of 79 ribosomal proteins. The gene encoding RPS19 is mutated in approximately 25% of patients with Diamond-Blackfan anemia, which is a rare congenital erythroblastopenia. Affected individuals present with decreased numbers or the absence of erythroid precursors in the bone marrow, and associated malformations of various organs are common. We produced C57BL/6J mice with a targeted disruption of murine Rps19 to study its role in erythropoiesis and development. Mice homozygous for the disrupted Rps19 were not identified as early as the blastocyst stage, indicating a lethal effect. In contrast, mice heterozygous for the disrupted Rps19 allele have normal growth and organ development, including that of the hematopoietic system. Our findings indicate that zygotes which are Rps19(-/-) do not form blastocysts, whereas one normal Rps19 allele in C57BL/6J mice is sufficient to maintain normal ribosomal and possibly extraribosomal functions.  (+info)

This study will test whether the immune-suppressing drug rituximab can increase blood counts and reduce the need for transfusions in patients with moderate aplastic anemia, pure red cell aplasia, or Diamond Blackfan anemia. These are rare and serious blood disorders in which the immune system turns against bone marrow cells, causing the bone marrow to stop producing red blood cells in patients with pure red cell aplasia and Diamond Blackfan anemia, and red blood cells, white blood cells and platelets in patients with aplastic anemia. Rituximab is a laboratory-made monoclonal antibody that recognizes and destroys white blood cells called lymphocytes that are responsible for destroying bone marrow cells in these diseases. The drug is currently approved by the Food and Drug Administration for treating patients with B-cell non-Hodgkin lymphoma, a disease of white blood cells.. Participants receive four doses of rituximab, once a week for 4 weeks through a needle in an arm vein. The infusion rate ...
Diamond Blackfan anemia (DBA) is a lineage-selective inherited bone marrow failure syndrome characterized primarily by anemia and physical malformations. Recent advances in identifying the genetic abnormalities underlying DBA have demonstrated involvement of genes encoding both large (RPL) and small (RPS) ribosomal subunit proteins, including mutations of RPL5, RPL11, RPL35A, RPS7, RPS10, RPS17, RPS19, RPS24, and RPS26 in 50% to 60% of affected patients. Despite significant progress, identification of gene abnormalities in the remaining patients remains an important question since present data suggest that mutations in other members of the ribosomal protein gene complement do not explain those cases without an identified genetic lesion in these genes. Genetic studies have also raised new questions with the recognition of substantial variability in the manifestations of DBA, ranging from ribosomal protein mutations in otherwise asymptomatic individuals to those with classic severe red blood cell ...
Diamond Blackfan Anemia (DBA) is a congenital bone marrow failure syndrome associated with ribosomal gene mutations that lead to ribosomal insufficiency. DBA is characterized by anemia, congenital anomalies, and cancer predisposition. Treatment for DBA is associated with significant morbidity. Here, we report the identification of Nemo-like kinase (NLK) as a potential target for DBA therapy. To identify new DBA targets, we screen for small molecules that increase erythroid expansion in mouse models of DBA. This screen identified a compound that inhibits NLK. Chemical and genetic inhibition of NLK increases erythroid expansion in mouse and human progenitors, including bone marrow cells from DBA patients. In DBA models and patient samples, aberrant NLK activation is initiated at the Megakaryocyte/Erythroid Progenitor (MEP) stage of differentiation and is not observed in non-erythroid hematopoietic lineages or healthy erythroblasts. We propose that NLK mediates aberrant erythropoiesis in DBA and is ...

Diamond-Blackfan anemia (DBA) is a congenital bone marrow failure syndrome characterized by erythroid hypoplasia, usually without perturbation of other hematopoietic lineages. Approximately 65% of DBA patients with autosomal dominant inheritance have heterozygous mutations or deletions in ribosomal protein (RP) genes while ,1% of patients with X-linked inheritance have been identified with mutations in the transcription factor GATA1. Erythroid cells from patients with DBA have not been well characterized, and the mechanisms underlying the erythroid specific effects of either RP or GATA1 associated DBA remain unclear. We have developed an ex vivo culture system to expand peripheral blood CD34+ progenitor cells from patients with DBA and differentiate them into erythroid cells. Cells from patients with RP or GATA1 mutations showed decreased proliferation and delayed erythroid differentiation in comparison with controls. RNA transcript analyses of erythroid cells from controls and patients with RP ...
Scientists recommend testing for Pearson syndrome in patients with congenital anemia. Some babies diagnosed with and treated for a bone marrow failure disorder, called Diamond Blackfan Anemia, may actually be affected by a very rare anemia syndrome that has a different disease course and treatment, say scientists from Dana-Farber/Boston Childrens Cancer and Blood Disorders Center.. Genetic analysis of DNA from 175 patients believed to have Diamond Blackfan Anemia, identified eight that showed hallmarks of Pearson Marrow Pancreas syndrome, according to research presented at the 55th annual meeting of the American Society of Hematology.. The treatment choices are difficult in both syndromes, but getting the diagnosis correct is crucial, said Suneet Agarwal, MD, PhD, a pediatric hematologist/oncologist at Dana-Farber/Boston Childrens.

Diamond-Blackfan anemia (DBA) is a severe congenital anemia characterized by a defect in red blood cell production. The disease is associated with growth retardation, malformations, a predisposition for malignant disease and heterozygous mutations in either of the ribosomal protein (RP) genes RPS7, RPS17, RPS19, RPS24, RPL5, RPL11 and RPL35a.In a cellular model for DBA, siRNA knock-down of RPS19 results in a relative decrease of other ribosomal (r) proteins belonging to the small subunit (RPS20, RPS21, RPS24) when compared to r-proteins from the large ribosomal subunit (RPL3, RPL9, RPL30, RPL38). RPS19 mutant cells from DBA patients show a similar and coordinated down-regulation of small subunit proteins. The mRNA levels of the small subunit r-proteins remain relatively unchanged. We also show that RPS19 has an extensive number of transcriptional start sites resulting in mRNAs of variable 5UTR length. The short variants are translated more efficiently. Structural sequence variations in the ...
Diamond Blackfan Anemia (DBA) was first recognized as a distinct entity in 1938, although it was called "congenital hypoplastic anemia" at that time. Diamond Blackfan Anemia ("DBA") is a rare blood disorder, characterized by a failure of the bone marrow (the center of the bone where blood cells are made) to produce red blood cells. This failure causes DBA patients to become severely anemic. It is important to note that this anemia is not the result of a deficiency in iron, vitamin B-12, folate, or erythropoietin, which is a blood cell stimulating factor. Although a number of theories regarding the cause of DBA have been proposed, it is now widely accepted that DBA is a ribosomal protein disease. The disorder results from an intrinsic progenitor cell defect in which erythroid progenitors and precursors are highly sensitive to death by apoptosis (self-destruction). The accepted diagnostic criteria for DBA are:. ...

There are two common forms of treatment:. Steroid therapy: Approximately 70% of people diagnosed with DBA have steroid therapy which improves their anaemia. However, in some cases steroid therapy can stop working and the anaemia may return. Sometimes steroid therapy is used in combination with cyclosporin A. Those who respond to steroid treatment may remain on steroids for the rest of their lives.. Blood transfusions: For those who do not respond to steroid treatment, regular blood transfusions may be required. It is important to note that recipients of regular blood transfusions may be at risk of iron overload*. Iron overload occurs when there is a buildup of iron in the body as a result of blood transfusions. It is important to discuss this with your health care professional.. ...
The ATR-Chk1 axis has recently been implicated in cell-cycle arrest that is induced by a prolonged treatment with low levels of actinomycin D, a selective inhibitor of rRNA synthesis (Ma and Pederson, 2013). The exact mechanism of ATR induction by this treatment was not uncovered.. The phosphorylation of p53 at residues Ser15 and Ser37 observed in RPS19-deficient human CD34+ fetal liver cells is probably performed by multiple protein kinases, including ATR, ATM, Chk1 and Chk2, the activation of which was observed in these cells. Phosphorylation at these sites is known to stabilize and activate p53, but other mechanisms could also contribute to p53 activation (Ashcroft et al., 2000; Lane and Levine, 2010).. Changes in the expression of enzymes involved in nucleotide metabolism in models of DBA are consistent with the requirement of RP-deficient cells to catabolize the defective rRNA, produce more nucleotides to make new rRNAs and to make increased amounts of dNTPs sufficient for DNA repair. ...

article{a4771b6c-1150-427f-a70a-c2fe50a441ba, abstract = {Diamond-Blackfan anemia (DBA) is a congenital bone marrow failure syndrome characterized by a specific deficiency in erythroid progenitors. Since some patients with DBA develop a reduction in thrombocytes and granulocytes with age, we asked whether multipotent hematopoietic progenitors from DBA patients had normal proliferative capacity in liquid expansion cultures. CD34(+) cells derived from DBA patients showed deficient proliferation in liquid culture containing IL-3, IL-6, and SCF. Single CD34(+) CD38(-) cells from DBA patients exhibited deficient proliferation recruitment in a limiting dilution assay containing IL-3, IL-6, SCF, Tpo, FIL, and G-CSF or containing IL-3, IL-6, and SCF. Our findings suggest that the underlying hematopoietic defect in DBA may not be limited to the erythroid lineage.

For about 10 years, RPS19 seemed to be the only gene involved in the pathogenesis of DBA and mutations in this gene accounted for 25% of cases.9 In the last 3 years, however, heterozygous mutations in several genes encoding ribosomal proteins of either the small or the large ribosomal subunit have been reported.3-7 Specifically, Gazda et al. found mutations in RPL5 and RPL11 in about 7% and 5%, respectively, of DBA patients,6 while Cmejla et al. showed a higher frequency of RPL5 (21%) and RPL11 (7%) mutations among Czech patients.7. We report here the results of our screening of RPS24, RPL5 and RPL11 in 92 Italian patients who were negative for RPS19 mutations. No mutations were found in RPS14, RPS16, and RPL35A..

Many cases of Aase syndrome occur without a known reason and are not passed down through families (inherited). However, some cases (45%) have been shown to be inherited. These are due to a change in 1 of 9 genes important for making protein correctly (the genes make ribosomal proteins). This condition is similar to Diamond-Blackfan anemia, and the 2 conditions should not be separated. A missing piece on chromosome 19 is found in some people with Diamond-Blackfan anemia.. The anemia in Aase syndrome is caused by poor development of the bone marrow, which is where blood cells are formed. ...

People with inherited syndromes such as Fanconi anemia, Diamond Blackfan anemia, familiar platelet disorder, severe congenital neutropenia or Shwachman-Diamond syndrome may also have a higher risk of developing a myelodysplastic syndrome due to the genetic defects that cause these conditions to develop. Additionally, these inherited syndromes are commonly treated with bone marrow transplants, which is often performed with a high-dose course of chemotherapy. This chemotherapy can further increase a persons risk of developing MDS.. Additionally, a history of exposure to environmental and occupational carcinogens such as benzene, chemical fertilizers, nitro-organic explosives and diesel derivatives can also increase a persons risk of developing a myelodysplastic syndrome. Studies have found higher rates of these syndromes among industrial workers such as plant and machine operators and assemblers, as well as in coal miners and agricultural workers. Regardless of a persons occupational history, ...
Fanconi Anemia is an inherited anemia which leads to bone marrow failure (aplastic anemia). It is also know as Diamond Blackfan Anemia/Syndrome.
Some babies diagnosed with and treated for a bone marrow failure disorder, called Diamond Blackfan Anemia, may actually be affected by a very rare anemia syndrome that has a different disease course and treatment, say scientists from Dana-Farber/Boston Children's Cancer and Blood Disorders Center.
One of a series of posts honoring ‪#RareDiseaseDay (Feb 28, 2015).. Historically, the starting point for making a rare disease diagnosis is the patients clinical profile: the set of symptoms and features that together define Diamond Blackfan anemia (DBA), Niemann-Pick disease or any of a thousand other conditions.. For example, anemia and problems absorbing nutrients are features of Pearson marrow pancreas syndrome (PS), whereas oddly shaped fingernails, lacy patterns on the skin and a proneness to cancer point to dyskeratosis congenita (DC).. The resulting diagnoses give the child and family an entry point into a disease community, and is their anchor for understanding whats happening to them and others: "Yes, my child has that and heres how it affects her. Does it affect your child this way too?". But as researchers probe the relationships between genes and their outward expression-between genotype and phenotype-some families are losing that anchor. They may discover that their child ...
Haematopoietic stem cells found in cord blood and bone marrow produce healthy blood cells, which have proven to treat aplastic, Fanconi, sickle cell and diamond blackfan anaemia.

N2 - Over expression of hepcidin antimicrobial peptide is a common feature of iron-restricted anemia in humans. We investigated the erythroid response to either erythropoietin or RAP-011, a "murinized" ortholog of sotatercept, in C57BL/6 mice and in hepcidin antimicrobial peptide 1 over expressing mice. Sotatercept, a soluble, activin receptor type IIA ligand trap, is currently being evaluated for the treatment of anemias associated with chronic renal disease, myelodysplastic syndrome, β-thalassemia, and Diamond Blackfan anemia and acts by inhibiting signaling downstream of activin and other Transforming Growth Factor-β superfamily members. We found that erythropoietin and RAP-011 ...

This prayer update was born when I realized, to my horror, that I had accidentally left a couple of people off of my last prayer update. I set out to rectify this with the first ever .5 update, but then more people kept popping up needing to be put on, and more updates kept coming in from current friends. So, in short, we have a full-fledged prayer update 11. =) Thank you for reading, and for praying! You can reach the full prayer list right here.. First we have Amanda, who I feel so bad for leaving off from the list for prayer update 10. Amanda had Diamond Blackfan Anemia, and that has developed into Myelodysplasia, which is a disease where the bone marrow essentially becomes corrupted and blood cells are not properly produced any longer. It is often treated with a bone marrow transplant and chemo therapy, but they have informed her that a bone marrow transplant is not an option for her. There was a 50% chance that she could develop this or acute myeloid leukemia, and this is better than the ...
I believe it is no coincidence that Long Islands Newsday chose this week to run a five-part series on the Katie Trebing Story, reported by Beth Whitehouse. The Trebings used preimplantation genetic diagnosis (PGD) and in vitro fertilization to create the "perfect sibling" for the purpose of a bone marrow transplant to hopefully cure their daughter Katies Diamond Blackfan anemia. In the process, a total of 37 embryos were created. Only three were considered "good candidates" for implantation; the result was one successful pregnancy. The story is available at www.newsday.com/thematch. Whitehouse will be available for a live chat at the web site this Tues. and Wed. at 12:30 p.m. Stacy and Steve Trebing will be in the chat room on Thurs. at 12:30 p.m. Perhaps some of you can log in to make your voices heard ...
Although not an artist in the typical sense, buncees CEO and founder Marie Arturi epitomizes Vashtis courage as she makes her mark on the world. After a personal loss to Diamond Blackfan Anemia, a rare blood disease, Marie created the Daniella Maria Arturi Foundation. In fact, it was after one of the foundations events that the idea for buncee came about! She needed a way to create unique and personal digital content, and with a pinch of creative problem solving and a dash of courage, voila! Buncee came into being. It is the buncee teams hope that as buncee grows, we can give back to the Daniella Marie Arturi Foundation. ...
Diamond-Blackfan anaemia (DBA) is a rare cause of bone marrow failure. The incidence of malignancy and endocrine complications are increased in DBA, relative to other inherited bone marrow failure syndromes. We describe an adult woman with DBA who developed osteoporosis and avascular necrosis (AVN) of both distal femora. Such endocrine complications are not uncommon in DBA, but under-appreciated, especially in adulthood. Further, rectal adenocarcinoma was diagnosed at age 32 years, requiring hemi-colectomy and adjuvant chemotherapy. Elevated cancer risk may warrant disease-specific screening guidelines. Genetic predictors of extra-haematopoetic complications in DBA are yet to be established. ...

Ribosomal proteins (RP) regulate specific gene expression by selectively translating subsets of mRNAs. Indeed, in Diamond-Blackfan anemia and 5q- syndrome, mutations in RP genes lead to a specific defect in erythroid gene translation and cause anemia. Little is known about the molecular mechanisms of selective mRNA translation and involvement of ribosomal-associated factors in this process. Ribonuclease inhibitor 1 (RNH1) is a ubiquitously expressed protein that binds to and inhibits pancreatic-type ribonucleases. Here, we report that RNH1 binds to ribosomes and regulates erythropoiesis by controlling translation of the erythroid transcription factor GATA1. Rnh1-deficient mice die between embryonic days E8.5 and E10 due to impaired production of mature erythroid cells from progenitor cells. In Rnh1-deficient embryos, mRNA levels of Gata1 are normal, but GATA1 protein levels are decreased. At the molecular level, we found that RNH1 binds to the 40S subunit of ribosomes and facilitates polysome ...
