Mutations affecting genes encoding ribosomal proteins cause Diamond Blackfan anemia (DBA), a rare congenital syndrome associated with physical anomalies, short stature, red cell aplasia, and an increased risk of malignancy. p53 activation has been identified as a key component in the pathophysiology of DBA after cellular and molecular studies of knockdown cellular and animal models of DBA and other disorders affecting ribosomal assembly or function.

DBA causes low red blood cell counts (), without substantially affecting the other blood components (the platelets and the white blood cells), which are usually normal. Diamond-Blackfan anemia is an inherited blood disorder that affects the ability of the bone marrow to produce red blood cells. Symptoms may include a shortage of red blood cells (anemia), physical abnormalities such as small head size (microcephaly) characteristic facial features, cleft palate, cleft lip, short and webbed neck, small shoulder blades, and defects of the hands (mostly of the According to the DBAR, the average age of presenting with anemia is two months and the average age of diagnosis with DBA is four and a half months. Patients with DBA typically present with common symptoms of anemia, including pale skin, sleepiness, irritability, rapid heartbeat, and heart murmurs.

Genetic and Rare Diseases Information Center. Diamond-blackfan Diamond Blackfan anaemia, is a rare, inherited bone marrow failure syndrome, which occurs, when your bone marrow, don't manufacture, enough red blood cells, to meet your body's requirements, without substantially affecting, the other blood components, the platelets, and the white blood cells (WBCs), which are usually normal. Diamond Blackfan Anemia (DBA) in Children What is DBA in children? Diamond Blackfan anemia (DBA) is a rare blood disorder. Children with DBA do not make enough red blood cells. These cells carry oxygen to all other cells in the body.

According to the DBA Registry, the average age of those presenting with anemia is 2 months, and the average age of diagnosis of DBA is 4 months.

A marrow biopsy showing less than 25 percent of normal cellularity; OR o Diamond-Blackfan anemia (DBA) o Fanconi's anemia (FA) o Schwachman- Diamond syndrome (SDS) o Chronic illness with one year or less life expectancy.

In DBA, the bone marrow (the center of the bone where blood cells are made) does not make enough red blood cells that carry oxygen throughout the body. What causes DBA? DBA is usually diagnosed during the first year of life. The major function of bone marrow is to produce new blood cells. In Diamond-Blackfan anemia, the bone marrow malfunctions and fails to make enough red blood cells, which carry oxygen to the body's tissues.

Excerpted from the GeneReview: Diamond-Blackfan Anemia The hematologic complications occur in 90% of affected individuals during the first year of life. The phenotypic spectrum ranges from a mild form (e.g., mild anemia, no anemia with only subtle erythroid abnormalities, physical malformations without anemia) to a severe form of fetal anemia resulting in nonimmune hydrops fetalis.

Thalassemia Shortened red cell life span and splenic trapping Often confused with Diamond–Blackfan anemia and transient erythroblastopenia of childhood 21 Jul 2012 Anaemia is a condition in which your blood has a lower than normal number of red and Diamond-Blackfan anaemia may also cause aplastic anaemia. and removed from the bloodstream before their normal lifespan is up. Abstract.

People with this condition often also have physical abnormalities affecting various parts of the body.The major function of bone marrow is to produce new blood cells. In Diamond-Blackfan anemia, the bone marrow malfunctions and fails to make enough red blood cells, which carry oxygen to the body's tissues. Molecular pathophysiology of Diamond-Blackfan anemia (DBA) involves disrupted erythroid-lineage proliferation, differentiation and apoptosis; with the activation of p53 considered as a key component. Recently, oxidative stress was proposed to play an important role in DBA pathophysiology as well.
