114,800 (2015) [8] 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]
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 ...
The molecular disease concept put forward in the 1949 paper also became the basis for Linus Pauling's view of evolution. In the 1960s, by which time it had been shown that sickle cell trait confers resistance to malaria and so the gene had both positive and negative effects and demonstrated heterozygote advantage, Pauling suggested that ...
Transfusion therapy for sickle-cell disease entails the use of red blood cell transfusions in the management of acute cases of sickle cell disease and as a prophylaxis to prevent complications by decreasing the number of red blood cells (RBC) that can sickle by adding normal red blood cells.

The Sickle Cell Disease Association of America, Inc. originated in Racine, Wisconsin. Representatives from 15 different community-based sickle cell organizations came together at Wingspread, a community center, as guest of the Johnson Foundation. There was a common belief that there was a need for national attention to sickle cell disease.
A vaso-occlusive crisis is a common painful complication of sickle cell anemia in adolescents and adults. It is a form of sickle cell crisis. Sickle cell anemia – most common in those of African, Hispanic, and Mediterranean origin – leads to sickle cell crisis when the circulation of blood vessels is obstructed by sickled red blood cells, causing ischemic injuries. The most common ...
Hemoglobin electrophoresis is a blood test that can detect different types of hemoglobin. The test can detect hemoglobin S, the form associated with sickle cell disease, as well as other abnormal types of hemoglobin, such as hemoglobin C. It can also be used to investigate thalassemias, which are disorders caused by defective hemoglobin production.

Roland Boyd Scott (April 18, 1909 – December 10, 2002) was an American researcher, pediatrician and authority on sickle cell disease. Scott authored a key paper in 1948 describing the incidence of sickle cell in infants that eventually led to the establishment of routine screening for newborns.
