Hereditary spherocytosis is an abnormality of red blood cells, or erythrocytes. The disorder is caused by mutations in genes relating to membrane proteins that allow for the erythrocytes to change shape. The abnormal erythrocytes are sphere-shaped (spherocytosis) rather than the normal biconcave disk shaped. Hereditary spherocytosis (HS) is a heterogeneous group of disorders with regard to clinical severity, protein defects and mode of inheritance. It is relatively common in Caucasian populations; most affected individuals have mild or only moderate haemolysis.

Hereditary spherocytosis (HS) is the most common cause of nonimmune hemolytic anemia and the third most common cause of kernicterus after glucose-6-phosphate-dehydrogenase deficiency and ABO isoimmunization. Awareness of the clinical Hereditary Spherocytosis What is Hereditary Spherocytosis? As the name implies, Hereditary Spherocytosis (or HS) is an inherited disorder where the red blood cells have an abnormal shape. Normal red cells have a doughnut shape where as people with HS have spherical red cells, which have a shortened life span due to destruction by the spleen.
This produces membrane instability that forces the cell to the smallest volume--a sphere.

Normal red cells have a doughnut shape where as people with HS have spherical red cells, which have a shortened life span due to destruction by the spleen.
Hemolytic crisis and persistent anemia have been reported during pregnancy, especially in women who have not undergone splenectomy.  One article reported on 8 patients with HS who had a total of 19 pregnancies: 10 pregnancies occurred in patients before splenectomy, and 9 occurred after splenectomy. Hereditary Spherocytosis. Hereditary spherocytosis (HS) occurs in one in 2,500 to 5,000 persons of Northern European descent 82,83 and is the most common hereditary RBC membrane defect that leads to acute hemolysis and hyperbilirubinemia in the newborn.

May 12, 2020 The autosomal dominant inheritance pattern is responsible for three-quarters of all cases, but the disease can also occur due to spontaneous Jul 8, 2009 Hereditary spherocytosis is a relatively common disorder (as far as hematologic disorders go): 1 in 5,000 people of Northern European descent Some genetic conditions exhibit a simple inheritance pattern called Mendelian Inheritance. This type of inheritance only occurs where the disease is caused by Paul Andersen describes genetics at the chromosomal level. He begins with a simple monohybrid cross as viewed through Mendelian genetics and then shows Nov 30, 2018 inherited, clinically heterogeneous red blood cell membrane disorder Perrotta S, Gallagher PG, Mohandas N. Hereditary spherocytosis. Dec 12, 2016 Hereditary spherocytosis (HS) is the most common cause of molytic anemia due to an inherited red blood cell (RBC) membrane disorder.

Hereditary Spherocytosis, Hereditary Elliptocytosis, and Other Disorders Associated with Abnormalities of the Erythrocyte Membrane Patrick G. Gallagher Bertil Glader This chapter focuses on hemolytic disorders and abnormalities of red blood cell (RBC) shape resulting from alterations of the erythrocyte membrane. In hereditary spherocytosis, there is a lack of spectrin, a key RBC cytoskeletal membrane protein. This produces membrane instability that forces the cell to the smallest volume--a sphere. In the laboratory, this is shown by increased osmotic fragility. Hereditary Spherocytosis - A Rare Case Report Nigwekar P*, Shrikhande D Y**, Niranjan B K, Shah N, Shukla T Abstract Eleven years old female child presented with severe anemia, jaundice and moderate splenomegaly. Her hematological parameters supported diagnosis of hereditary spherocytosis. Father died of similar illness at the age of 40 years.
