ABSTRACT Introduction: Patients with sickle-cell disease (SCD) present chronic hemolysis with increased serum biomarkers. Genetic polymorphisms of the BLC11A gene modulate fetal hemoglobin (HbF), thus reducing hemolysis Objective: To associate the polymorphisms of BCL11A gene with the hemolysis markers: reticulocyte, bilirubin, uric acid, lactate dehydrogenase (LDH), and methemoglobin (MetHb) in SCD patients.
