Sickle Cell Disorders
Sickle Cell Disorders
- Sickle cell disease (hemoglobin SS disease) occurs when both genes produce hemoglobin S. This person typically has symptoms of anemia , mild to life-threatening complications, and a shortened lifespan.
- Sickle beta-thalassemia occurs when a person has one hemoglobin S gene and another gene that causes the body to produce less hemoglobin than normal. This person may have mild to severe sickle cell disease.
- Hemoglobin SC disease occurs when a person has one hemoglobin S gene and one abnormal hemoglobin C gene. This person may have generally milder symptoms and a longer lifespan than a person with sickle cell disease but still may become seriously ill.
- Hemoglobin SE disease occurs when a person has one hemoglobin S gene and one abnormal hemoglobin E gene. This person may have mild anemia. Most people do not have symptoms.
- Hemoglobin SO disease and hemoglobin SD disease occur when a person has one hemoglobin S gene and one abnormal hemoglobin O or hemoglobin D gene. This person may experience all sickle cell disease symptoms, ranging from mild to severe.
