Bone Marrow Failure Syndrome Treatment and Know More
Blood cell are made in the bone marrow and released into the peripheral bloodstream.
There are three types of blood cells in the body:
- White blood cells, which work to fight infection.
- Red blood cells contain hemoglobin, carry iron and deliver oxygen to tissues throughout the body.
- Platelets, which help form clots and stop bleeding.
All these cells and their precursors are produced in the bone marrow before maturing and being released into the bloodstream. The bone marrow is located in the long bones of the body, namely the hips and upper legs. Bone marrow failure syndromes (BMFS) can result when blood cells are not produced adequately. It may present with only one decreased cell line or with all three cell lines being low (pancytopenia). Low peripheral blood counts can indicate bone marrow failure.
Bone marrow failure syndromes may be present at birth or develop later in life. Some bone marrow failure syndromes are due to an underlying inherited genetic condition. In contrast, other bone marrow failure syndromes are due to an acquired cause such as viral or drug/toxin exposures. In many cases of bone marrow failure, the underlying cause cannot be identified, and the term “idiopathic” is used. Bone marrow failure can manifest as one isolated cytopenia (one blood cell type decreased) or pancytopenia (all three blood cell types decreased).

- Amegakaryocytic thrombocytopenia (Amega)
- Diamond Blackfan anemia (DBA)
- Dyskeratosis congenita (DC)
- Fanconi anemia (FA)
- Aplastic anemia
- Pearson syndrome
- Severe congenital neutropenia (SCN)
- Shwachman Diamond syndrome (SDS)
- Thrombocytopenia absent radii (TAR)
- Other bone marrow failure syndromes
Fanconi anemia
Fanconi anaemia is the most common type of bone marrow failure. This condition prevents people from producing normal white blood cells, red blood cells, or platelets. Children with Fanconi anaemia may be shorter than their peers and have unusual skin colour, unusual thumbs, and small eyes. They are also more likely to develop myelodysplastic syndrome (MDS), leukaemia, and/or solid tumours of the head and neck.
Congenital amegakaryocytic thrombocytopenia
A mutation in the gene called MPL causes congenital amegakaryocytic thrombocytopenia (CAMT). This mutation increases the risk of leukaemia by causing problems with red and white blood cells and platelets. CAMT can cause bruising, bleeding, deformed thumbs, and short stature in children.
Diamond blackfan anemia
Diamond-Blackfan anaemia (DBA) causes children to produce a low amount of red blood cells. Their platelet and white blood cell counts typically remain normal. Mutations in genes that control a cell's ability to generate specific proteins cause this disorder. DBA patients may have abnormal thumbs and be shorter than others of their age group.
Dyskeratosis congenita
Dyskeratosis congenita affects white blood cells, red blood cells, and platelets. Children with this disorder may have darkened areas of skin or abnormal skin colour, nail changes, white patches in the mouth, abnormal thumbs, small eye size, and be shorter than others of their age group.
Shwachman diamond syndrome
Shwachman Diamond syndrome affects the synthesis of white blood cells initially and then moves on to red blood cells and platelets. They may have bone abnormalities as well as liver and pancreatic disorders, which can interfere with fat absorption in the body. Shwachman Diamond syndrome children may also have abnormal skin colour, abnormal thumbs, small eye size, and be shorter than other children of their age.
Thrombocytopenia absent radii
Children with thrombocytopenia have no radii and one of the two lower arm bones (known as the radius) is absent . These patients are also more prone to bruising.
