WebSpherocytosis is one of the most common inherited hemolytic anemias. It is caused by a defect in the erythrocyte membrane, which leads to an increased permeability for sodium and water, giving the erythrocyte its typical spherical form. This renders the erythrocytes susceptible to phagocytosis in the spleen at an early age. WebSpherocytes are red blood cells with a molecular defect in one or more proteins in the cytoskeleton of red blood cells. Due to its defect in the cytoskeleton, the RBC contracts …
