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 ...
Specialty. Hematology. Hemoglobinopathy is the medical term for a group of inherited blood disorders involving the hemoglobin, the protein of red blood cells. [1] They are single-gene disorders and, in most cases, they are inherited as autosomal co-dominant traits. [2]
Sickle Cell Anemia, a Molecular Disease. " 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.
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.
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 ...
Mendelian traits in humans. A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition. [1]
Other names. Sickle cell-β thalassemia. Specialty. Hematology. Sickle cell-beta thalassemia is an inherited blood disorder. The disease may range in severity from being relatively benign and like sickle cell trait to being similar to sickle cell disease. [1] [2]
