Hereditary red cell membrane disorders
Nonimmune anemias Hereditary red cell membrane disorders are accounted for by nonimmune hereditary hemolytic anemias caused by defects in membrane proteins located in distinct layers of the red cell membrane. Hereditary spherocytosis (HS), hereditary elliptocytosis (HE), and hereditary pyropoikilocytosis (HPP) are disorders of the red cell cytoskeleton, whereas hereditary stomatocytoses are consistent with disorders of
