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]
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.
This was the first step to learning all of what we know genetically about sickle cell disease. He found that the sickle cell trait itself was heterozygous and the disease was expressed when the gene was recessive homozygous. This was very difficult to figure out at the time with the current knowledge and while he did not find the relationship ...
"Sickle Cell Anemia, a Molecular Disease" is a 1949 scientific paper by Linus Pauling, Harvey A. Itano, Seymour J. Singer and Ibert C. Wells that established sickle-cell anemia as a genetic disease in which affected individuals have a different form of the metalloprotein hemoglobin in their blood.
In November 1949, Pauling, Harvey Itano, S. J. Singer and Ibert Wells published "Sickle Cell Anemia, a Molecular Disease" [66] in the journal Science. It was the first proof of a human disease being caused by an abnormal protein, and sickle cell anemia became the first disease understood at the molecular level.
The 43-year-old had diagnoses of sickle cell disease, epilepsy and delusional disorder, and a jury found that he died of acute chest syndrome – the most common fatal complication of sickle cell ...
