Summary
Hereditary spherocytosis (HS) is an autosomal dominant genetic disorder in which red blood cells are sphere-shaped instead of having the normal biconcave shape. These abnormal red blood cells break down prematurely, which can lead to anemia. Also, because of their abnormal shape, red blood cells in spherocytosis don't move through small blood cells efficiently as normal ones do, which can affect tissue oxygenation. People with hereditary spherocytosis can present with jaundice, splenomegaly, and features of anemia like pallor and fatigue.
