WebSickle-cell anemia is a genetic condition in which red blood cells, which are normally round, take on a crescent-like shape (Figure 3.2). The changed shape of these cells affects how they function: sickle-shaped cells can clog blood vessels and block blood flow, leading to high fever, severe pain, swelling, and tissue damage. WebTanzania has identified Sickle Cell Disease (SCD) as a ‘perfect model’ to test this paradigm because it is a monogenic disorder with considerable phenotypic variation and causes a significant burden of disease to individuals and the health system.

WebSickle cells live only for about 15 days. Normal hemoglobin cells can live up to 120 days. Sickle cells risk being destroyed by the spleen because of their shape and stiffness. The spleen helps filter the blood of infections. Sickle cells get "stuck" in this filter and die. Due to the decreased number of hemoglobin cells circulating in the body ... WebSickle cell anemia is caused by a mutation in the gene that tells your body to make the red, iron-rich compound that gives blood its red color (hemoglobin). Hemoglobin allows red blood cells to carry oxygen from your lungs to all parts of your body.
