Hereditary elliptocytosis-3 (EL3) is a hemolytic disorder characterized by the presence of elliptical erythrocytes and resulting in some cases in hemolytic anemia (summary by Qualtieri et al., 1997). For a general description and a discussion of genetic heterogeneity of hereditary elliptocytosis (HE), see EL1 (611804). [from OMIM]

Hereditary pyropoikilocytosis was originally described by Zarkowsky et al. (1975) as a distinct hemolytic anemia characterized by microspherocytosis, poikilocytosis, and an unusual thermal sensitivity of red cells. HPP is a subset of hereditary elliptocytosis (see 611804) due to homozygous or compound heterozygous mutations in spectrin leading to severe disruption of spectrin self-association (review by An and Mohandas, 2008). [from OMIM]
