Causes, incidence, and risk factors:

Elliptocytosis is inherited, usually as an autosomal dominant trait, affecting approximately 1 in every 4,000 people. In mild cases, fewer than 15% of red blood cells are elliptical. Elliptocytosis is frequently harmless, although some people may experience hemolytic crises where the red blood cells rupture, releasing their hemoglobin. Affected individuals can develop anemia, jaundice, and gallstones.
