WebSpectrin deficiency is the most common cause of this disorder. Spectrin deficiency leads to loss of erythrocyte surface area, which produces spherical RBCs. Spherocytic RBCs are rapidly removed from the circulation by the spleen. Patients with hereditary spherocytosis develop splenomegaly. Spectrin deficiency is due to impaired synthesis. WebNov 7, 2024 · Genetic alterations in alpha spectrin, beta spectrin, protein 4.1, band 3, and rarely glycophorin C result in failure of the elastic recoil property of normal RBCs in peripheral circulation resulting in an elliptical shape. These elliptocytes are trapped and removed by the spleen resulting in hemolytic anemia. helena okkonen
