Description: Sickle Cell Anemia is a recessive genetic disorder caused by a mutation that deforms the hemoglobin proteins in red blood cells leading to a sickle shape. Symptoms include intense pain, fatigue, stunted growth.
Cause: Sickle cell anemia is caused by a single mutation in the hemoglobin gene on chromosome 11 resulting in a change in the hemoglobin protein.
Inheritance: Sickle cell anemia is a recessive disorder. Patients who carry only one allele for the sickle cell mutation (Ss) are carriers of the sickle cell trait. Only people who inherit two mutated alleles have sickle cell anemia (ss).
Incidence: SCD affects 90,000 to 100,000 Americans. SCD occurs among about 1 out of every 500 Black or African-American births. SCD occurs among about 1 out of every 36,000 Hispanic-American births. SCT occurs among about 1 in 12 Blacks or African Americans. (Source: CDC)
Treatment: There is no cure for sickle cell anemia however you can treat the symptoms. Pain medication, Hydroxyurea (reduces painful crisis), blood transfusions, antibiotics (to prevent infections especially in children).
