hereditary spherocytosis
hereditary spherocytosis n a disorder of red blood cells that is inherited as a dominant trait and is characterized by anemia, small thick fragile spherocytes which are extremely susceptible to hemolysis, enlargement of the spleen, reticulocytosis, and mild jaundice

* * *

a group of clinically and genetically heterogeneous hereditary disorders characterized by the presence of spherocytes, hemolytic anemia, abnormal fragility of erythrocytes, jaundice, and splenomegaly; molecular defects affect various proteins important to the erythrocyte cytoskeleton. Called also congenital hemolytic or spherocytic anemia, and Minkowski-Chauffard syndrome.
