    A similar relationship exists between malaria and sickle-cell disease. One theory to explain this is that cells infected with the Plasmodium parasite are cleared more rapidly by the spleen . This phenomenon might give G6PD deficiency carriers an evolutionary advantage by increasing their fitness in malarial endemic environments.

    A well-studied case is that of sickle cell anemia in humans, a hereditary disease that damages red blood cells. Sickle cell anemia is caused by the inheritance of an allele (HgbS) of the hemoglobin gene from both parents. In such individuals, the hemoglobin in red blood cells is extremely sensitive to oxygen deprivation, which results in ...

    In 1954 he discovered, confirming his preconception, that people with sickle-cell trait are resistant to the deadly falciparum malaria. In the 1970s, Allison had worked out the enzyme, inosine monophosphate dehydrogenase , as a key molecule of the immune response in autoimmune diseases and in organ transplantation .

    Microcytic anaemia; Microcytosis is the presence of red cells that are smaller than normal. Normal adult red cell has a diameter of 7.2 µm. Microcytes are common seen in with hypochromia in iron-deficiency anaemia, thalassaemia trait, congenital sideroblastic anaemia and sometimes in anaemia of chronic diseases.

    Fetal hemoglobin, or foetal haemoglobin (also hemoglobin F, HbF, or α 2 γ 2) is the main oxygen carrier protein in the human fetus.Hemoglobin F is found in fetal red blood cells, and is involved in transporting oxygen from the mother's bloodstream to organs and tissues in the fetus.
