    en.wikipedia.org/wiki/Sickle_cell_disease

    Sickle cell disease (SCD), also simply called sickle cell, is a group of hemoglobin-related blood disorders that are typically inherited. [2] The most common type is known as sickle cell anemia. [2] Sickle cell anemia results in an abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [2]

  3. Sickle cell trait - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_trait

    The sickle cell trait provides a survival advantage against malaria fatality over people with normal hemoglobin in regions where malaria is endemic. The trait is known to cause significantly fewer deaths due to malaria, especially when Plasmodium falciparum is the causative organism.

  4. Pleiotropy - Wikipedia

    en.wikipedia.org/wiki/Pleiotropy

    Sickle cell anemia is a classic example of the mixed benefit given by the staying power of pleiotropic genes, as the mutation to Hb-S provides the fitness benefit of malaria resistance to heterozygotes as sickle cell trait, while homozygotes have significantly lowered life expectancy—what is known as "heterozygote advantage". Since both of ...

    en.wikipedia.org/wiki/Hemoglobin_Hopkins-2

    There is no red cell effect with Ho-2 compared to Hemoglobin S, which changes the shape of the cell to become sickled. The Hopkins-2 variant of hemoglobin is not involved in forming sickle cells. There is a lack of phenotypic expression of Ho-2 in terms of sickle cell, so a person with sickle cell and hemoglobin Hopkins-2 would be asymptomatic.

  6. Heterozygote advantage - Wikipedia

    en.wikipedia.org/wiki/Heterozygote_advantage

    Sickle-cell anemia (SCA) is a genetic disorder caused by the presence of two incompletely recessive alleles. When a sufferer's red blood cells are exposed to low-oxygen conditions, the cells lose their healthy round shape and become sickle-shaped. This deformation of the cells can cause them to become lodged in capillaries, depriving other ...

  9. Hemoglobin electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Hemoglobin_electrophoresis

    The test uses the principles of gel electrophoresis to separate out the various types of hemoglobin and is a type of native gel electrophoresis.After the sample has been treated to release the hemoglobin from the red cells, it is introduced into a porous gel (usually made of agarose or cellulose acetate) and subjected to an electrical field, most commonly in an alkaline medium.
