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 ...
The Sickle Cell Disease Association of America, Inc. (SCDAA) is a nonprofit organization with the sole purpose of supporting research, education and funding of individuals, families those who are impacted by sickle cell disease.
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).
The FDA approved a new treatment for sickle cell disease. The therapy is first to use the ground-editing tool CRISPR.
Sickle-cell disease and resistance to malaria In 1949 Allison participated in a vocational Oxford University Expedition to Mount Kenya. He took up the task of collecting blood samples from Kenyans for analyses of blood groups and genetic markers such as for sickle-cell disease.
James Bryan Herrick (11 August 1861 in Oak Park, Illinois – 7 March 1954 in Chicago, Illinois) was an American physician and professor of medicine who practiced and taught in Chicago. He is credited with the description of sickle-cell disease and was one of the first physicians to describe the symptoms of myocardial infarction.
Photomicrograph of normal-shaped and sickle-shape red blood cells from a patient with sickle cell disease Sickle cell anemia is a genetic disease that causes deformed red blood cells with a rigid, crescent shape instead of the normal flexible, round shape. [ 29 ] It is caused by a change in one nucleotide, a point mutation [ 30 ] in the HBB gene.
A vaso-occlusive crisis is a common painful complication of sickle cell anemia in adolescents and adults. [1][2] 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 ...
