Overview
Classification
Sideroblastic anemia may be classified according to its etiology into two groups:[1]
- Congenital
- Acquired
| Congenital sideroblastic anaemias | |
|---|---|
| X-linked | X-linked sideroblastic anaemia (XLSA)
X-linked sideroblastic anaemia with ataxia (XLSA/A) |
| Autosomal | Glutaredoxin-5 deficiency
Thiamine-responsive megaloblastic anaemia (TRMA) Associated with erythropoietic protoporphyria (EPP) Myopathy, lactic acidosis and sideroblastic anaemia (MLASA) |
| Mitochondrial DNA | Pearson syndrome |
| Acquired sideroblastic anaemias | |
|---|---|
| Acquired reversible SA | Alcoholism
Drugs (chloramphenicol, isoniazid) Copper deficiency (nutritional, zinc-induced, copper chelation) Vit B-6 deficiency |
| Acquired clonal SA | Refractory anaemia with ring sideroblasts (RARS)
Refractory anaemia with multilineage dysplasia and ring sideroblasts (RCMD) Refractory anaemia with ring sideroblasts and thrombocytosis (RARS-T) |
sideroblastic anemias can be subdivided according to red blood cell size (microcytic or normocytic-to-macrocytic)
| MCV decreased | MCV normal or increased |
|---|---|
| Isoniazid | Alcoholism |
| X-linked sideroblastic anemia (XLSA) in males | Copper deficiency |
| Autosomal recessive congenital sideroblastic anemia (ARCSA) | X-linked sideroblastic anemia (XLSA) in females |
| SIFD (ARCSA with immunodeficiency) | X-linked MLASA varian |
| Erythropoietic protoporphyria (EPP) | Pearson marrow-pancreas syndrome |
| X-linked sideroblastic anemia with ataxia | TRMA |
| MDS-RS-SLD | |
| MDS-RS-MLD | |
| MDS/MPN-RS-T |
MCV: mean corpuscular volume; XLSA: X-linked sideroblastic anemia; ARCSA: autosomal recessive congenital sideroblastic anemia; SIFD: sideroblastic anemia with B cell immunodeficiency, periodic fevers, and developmental delay; MLASA: myopathy, lactic acidosis, and sideroblastic anemia; TRMA: thiamine-responsive megaloblastic anemia; MDS-RS-SLD: myelodysplastic syndrome with ring sideroblasts and single lineage dysplasia; MDS-RS-MLD: myelodysplastic syndrome with ring sideroblasts and multilineage dysplasia; MDS/MPN-RS-T: myelodysplastic/myeloproliferative neoplasm with ring sideroblasts and thrombocytosis
