Spherocytosis is one of the most common inherited hemolytic anemias. It is caused by a defect in the erythrocyte membrane, which leads to an increased permeability for sodium and water, giving the erythrocyte its typical spherical form. This renders the erythrocytes susceptible to phagocytosis in the spleen at an early age.

13 Nov 2013 Hereditary spherocytosis. DAT (–). EMA flow (+). Persistent spherocytosis. MCHC /MCV elevated. (>36, likely >40) [15]. ABO hemolytic disease.

Spherocytosis most often refers to hereditary spherocytosis. This is caused by a molecular defect in one or more of the proteins of the red blood cell cytoskeleton , including spectrin , ankyrin , Band 3 , or Protein 4.2 . Hereditary Spherocytosis: • Most common hereditary hemol ytic disorder (red cell membrane) • Mutations of one of 5 genes (chromosome 8) for cytoskeletal proteins, overall effect is spectrin deficiency severity dependantdeficiency, severity dependant on spectrin deficiencyon spectrin deficiency • 200-300:million births, most common in Northern European countries Hereditary spherocytosis (HS) is a familial hemolytic disorder associated with a variety of mutations that lead to defects in red blood cell (RBC) membrane proteins. The morphologic hallmark of HS Hereditary spherocytosis (HS) is a disorder of the surface, called the membrane, of your red blood cells. It causes your red blood cells to be shaped like spheres instead of flattened discs that Newborn infants who have hereditary spherocytosis (HS) can develop anemia and hyperbilirubinemia. Bilirubin-induced neurologic dysfunction is less likely in these neonates if the diagnosis of HS is recognized and appropriate treatment provided. Among neonates listed in the USA Kernicterus Registry, HS was the third most common underlying hemolytic condition after glucose-6-phosphate dehydrogenase deficiency and ABO hemolytic disease.

3. Hereditary spherocytosis Hereditary spherocytosis (HS) (known as well as the Minkowski Chauffard disease) is the most common inherited red cell membrane disorder with one case out of 2000–3000 individuals, and probably even higher prevalence due to underdiagnosis of minor or moderate forms of HS (Table 1). Although more often diagnosed in 2021-04-07 · Background Hereditary spherocytosis (HS) is a common inherited disorder that is characterised by anaemia, jaundice, and splenomegaly. Clinical severity is variable with most patients having a well-compensated hemolytic anaemia. The primary lesion in HS is loss of membrane surface area, leading to reduced deformability due to defects in the membrane proteins ankyrin, band 3, beta spectrin There is currently no single index for the diagnostic screening of hereditary spherocytosis (HS). However, hematology analyzers are widely used in hospital laboratories because of their highly automated performance and quality control procedure, and detection of some blood cell parameters may be useful for the early screening of HS.

Reticulocytosis of 15 to 30% and leukocytosis are common.

The allele effects of Hsm1 on red cell volume are shown in Figure 5C ; the presence of 1 or 2 CAST alleles at the β-spectrin locus significantly lowers the MCV, suggesting Hsm1 is dominant. Hereditary spherocytosis is an inherited condition related to RBC destruction.
