  2. Sickle cell disease - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_disease

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

  3. Sickle cell trait - Wikipedia

    en.wikipedia.org/wiki/Sickle_cell_trait

    Hematology. Sickle cell trait describes a condition in which a person has one abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele (is homozygous). Those who are heterozygous for the sickle cell allele produce both ...

    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 ...

    Anthony Clifford Allison (21 August 1925 – 20 February 2014) was a South African geneticist and medical scientist who made pioneering studies on the genetic resistance to malaria. [2] Clark completed his primary schooling in Kenya, completed his higher education in South Africa, and obtained a BSc in medical science from the University of the ...

    A Rapid Diagnostic Test for Sickle Cell Anemia (1950) Harvey Akio Itano (Japanese: ハーベイ・アキオ・イタノ[1], November 3, 1920 – May 8, 2010) was an American biochemist best known for his work on the molecular basis of sickle cell anemia and other diseases. In collaboration with Linus Pauling, Itano used electrophoresis to ...

  8. Human genetic resistance to malaria - Wikipedia

    en.wikipedia.org/wiki/Human_genetic_resistance...

    Sickle-cell disease was the genetic disorder to be linked to a mutation of a specific protein. Pauling introduced his fundamentally important concept of sickle cell anemia as a genetically transmitted molecular disease. [20] This vein (4) shows the interaction between the malaria sporozoites (6) with sickle cells (3) and regular cells (1).

    Sickle Cell Anemia and its Protection Against Malaria.svg. English: In series A the red blood cell becomes sickled after interaction with the malarial merozoite, which then begins to multiply in the cell (schizont). Due to the heterozygous nature of the cell, and the hemoglobin inside it causing sickling, likely as a result of the lowering of ...
