Congenital hemolytic anemia (or hereditary hemolytic anemia) refers to hemolytic anemia which is primarily due to congenital disorders.
Basically classified by causative mechanism, types of congenital hemolytic anemia include:
- Genetic conditions of RBC Membrane
- Genetic conditions of RBC metabolism (enzyme defects). This group is sometimes called congenital nonspherocytic (hemolytic) anemia, which is a term for a congenital hemolytic anemia without spherocytosis, and usually excluding hemoglobin abdormalities as well, but rather encompassing defects of glycolysis in the erythrocyte.
- Hemoglobinopathies/genetic conditions of hemoglobin
