    en.wikipedia.org/wiki/Sickle_cell_trait

    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 ...

    Sickle cell – The gene for HbS associated with sickle-cell is today distributed widely throughout sub-Saharan Africa, the Middle East, and parts of the Indian subcontinent, where carrier frequencies range from 5–40% or more of the population.

    Sickle cell disease is a group of inherited disorders in which red blood cells — normally round — become hard, sticky and crescent shaped. The misshapen cells clog the flow of blood, which can ...

    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.

    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]

    en.wikipedia.org/wiki/Genetics

    Genetics is the study of genes, genetic variation, and heredity in organisms. [1] [2] [3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance ...

    en.wikipedia.org/wiki/Sickle_cell-beta_thalassemia

    Sickle cell-beta thalassemia is caused by inheritance of a sickle cell allele from one parent and a beta thalassemia allele from the other. Mutations. A sickle allele is always the same mutation of the beta-globin gene (glutamic acid to valine at amino acid six). In contrast, beta-thalassemia alleles can be created by many different mutations ...

    Indications for red blood cell transfusion. 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.
