WebSickle cell disease (SCD) is an autosomal recessive condition encompassing several abnormalities of the beta-globin gene. Patients are either homozygous for hemoglobin S (HbS; β S /β S) or have compound heterozygosity with a β S allele plus another mutant beta-globin gene, such as thalassemia (eg, β S /β 0).The abnormal HbS is less … The condition is asymptomatic, and is only noticed when screening for other hemoglobin disorders. In persons with sickle cell disease, high levels of fetal hemoglobin as found in a newborn or as found abnormally in persons with hereditary persistence of fetal hemoglobin, the HbF causes the sickle cell disease to be less severe. In essence the HbF inhibits polymerization of HbS. A simil…
