Congenital hemolytic anemia refers to hemolytic anemia which is primarily due to congenital disorders. Types Basically classified by causative mechanism, types of congenital hemolytic anemia include: Genetic conditions of RBC Membrane Hereditary spherocytosis Hereditary elliptocytosis 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 abnormalities as well, but rather encompassing defects of glycolysis in the erythrocyte. Glucose-6-phosphate dehydrogenase deficiency (G6PD or favism) Pyruvate kinase deficiency Aldolase A deficiency Hemoglobinopathies/genetic conditions of hemoglobin Sickle cell anemia Congenital dyserythropoietic anemia Thalassemia See also Hematopoietic ulcer List of circulatory system conditions References External links Hereditary hemolytic anemias
