Ineffective erythropoiesis is defined by the expansion of early-stage erythroid precursors driven by erythropoietin, accompanied by the apoptosis of late-stage precursors. . This mechanism is principally responsible for the anemia seen in acquired conditions such as certain subtypes of myelodysplastic syndrome (MDS) and inherited disorders such as β-thalassemia, inherited sideroblastic ...
Ineffective erythropoiesis: Ineffective erythropoiesis is an anemia caused by the premature apoptosis of the body's mature red blood cells [49] and subsequent reduction in an adequate production and full maturation of new healthy red blood cells.

Family history and ancestry are factors that increase the risk of beta thalassemia. Depending on family history, if a person's parents or grandparents had beta thalassemia major or intermedia, there is a 75% (3 out of 4) probability (see inheritance chart at top of page) of the mutated gene being inherited by an offspring.
Congenital dyserythropoietic anemia (CDA) is a rare blood disorder, similar to the thalassemias.CDA is one of many types of anemia, characterized by ineffective erythropoiesis, and resulting from a decrease in the number of red blood cells (RBCs) in the body and a less than normal quantity of hemoglobin in the blood.

In thalassemia, ineffective erythropoiesis causes the bone marrow to expand. This expansion is a compensatory response to the damage caused to red blood cells by the imbalanced production of globin chains. [28] Bone marrow expansion can lead to abnormal bone structure, particularly in the skull and face.
By the third or fourth month, erythropoiesis moves to the liver. [3] After seven months, erythropoiesis occurs in the bone marrow. Increased levels of physical activity can cause an increase in erythropoiesis. [4] However, in humans with certain diseases and in some animals, erythropoiesis also occurs outside the bone marrow, within the spleen ...
Dyserythropoiesis refers to the defective development of red blood cells, also called erythrocytes. [1] This problem can be congenital, acquired, or inherited. [2] Some red blood cells may be destroyed within the bone marrow during the maturation process, whereas others can enter the circulation with abnormalities. [3]
Reticulocytopenia is the medical term for an abnormal decrease in circulating red blood cell precursors (reticulocytes) that can lead to anemia due to resulting low red blood cell (erythrocyte) production. [1]
