The latest electronic edition of the journal Nature Genetics reports the discovery of a new gene responsible for congenital sideroblastic anemia.
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 ...
Abstract. Patients with inherited bone marrow failure syndromes (IBMFSs) classically present with specific patterns of cytopenias along with congenital anomali
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. Some patients with Diamond Blackfan will respond to steroids, but theres no reason to give steroids to someone with Pearson Syndrome -- and they could make things ...

Inherited bone marrow failure (IBMF) syndromes are a heterogeneous group of rare hematological disorders characterized by the impairment of hematopoiesis, which harbor specific clinical presentations and pathogenic mechanisms. Some of these syndromes may progress through clonal evolution, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Most prominent are failures of DNA repair such as Fanconi Anemia and much rarer failure of ribosomal apparatus, e.g., Diamond Blackfan Anemia or...
TY - JOUR. T1 - Clinical and Hematologic Benefits of Partial Splenectomy for Congenital Hemolytic Anemias in Children. AU - Rice, Henry E.. AU - Oldham, Keith T.. AU - Hillery, Cheryl A.. AU - Skinner, Michael A.. AU - OHara, Sara M.. AU - Ware, Russell E.. PY - 2003/2. Y1 - 2003/2. N2 - Objective: To assess the role of partial splenectomy for symptomatic children with various congenital hemolytic anemias. Summary Background Data: The use of total splenectomy for symptomatic children with congenital hemolytic anemias is restricted by concern of postsplenectomy sepsis. A partial splenectomy is an alternative procedure, although its utility remains incompletely defined. Methods: This longitudinal cohort study followed 25 symptomatic children with various congenital anemias who underwent partial splenectomy. Sixteen children had hereditary spherocytosis (HS), and nine children had other erythrocyte disorders. Outcome measures were clinical and laboratory hemolysis, splenic phagocytic and immune ...
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. ...
