Sickle cell anemia (SCA) refers to the condition associated with homozygosity for the Hgb S mutation (Hgb SS). Other Hgb mutations may occur with Hgb S causing a similar but milder condition. In SCA, the presence of intracellular hemoglobin S polymerization leads to chronic hemolytic anemia, vasoocclusive crises of varying severity and frequency with cumulative organ damage and systemic manifestations that include impairment in growth and development, susceptibility to infection, and reduced quality and duration of life Segal JB et al.
