Herrick wrote a report about a patient who suffered from a "strange disease" including such symptoms as asthmatic conditions and blood flow problems including body ulcers (Linde, 1972). Sickle Cell Anemia itself is not fatal, but it can cause complications that can become fatal. It is the most common type of hemoglobinopathy and is the result of a mutation in the β-globin chain gene that results in creating sickle hemoglobin (HbS) instead of the normal adult hemoglobin (HbA). Sickle cell anemia is an autosomal recessive genetic condition where the beta-globin protein subunit of hemoglobin is misshapen, which ultimately leads to a sickle-shaped red blood cell, which is prematurely destroyed and can get stuck in small blood vessels. Painful episodes due to blocked blood vessels can cause pain in the hands, feet, belly, back or chest. People who have sickle cell trait don't have sickle cell anemia or symptoms of the disease, but they can pass the sickle cell gene to their own children. For example, the American Society of Hematology. People with sickle cell trait are considered carriers and are usually asymptomatic. Homozygous Sickle Cell Disease (phenotype: FSS in infants and SS in adults) Commonly referred to as sickle cell anemia, homozygous sickle cell disease results when the gene for hemoglobin S is inherited from both parents. In many forms of the disease, the red blood cells change shape, usually looking much like that of a banana, upon deoxygenation because of polymerization of the abnormal sickle hemoglobin. It is not contagious. Sickle cell trait is generally a benign condition. Content is added by hematology & oncology professionals, and undergoes continuous peer review. Sickle-cell anaemia is caused by an inherited defect in the instructions which code for the production of haemoglobin, the oxygen-carrying pigment in red blood cells. Hyperhemolysis.
