Hemoglobinopathy: Patients with sickle cell anemia make an abnormal hemoglobin (hgb.). Normal HGB consists of paired protein chains (globin) and an iron containing part (heme). Patients with ssa inherit an abnormal beta-globin gene from each parent. Carriers have one normal beta-globin gene and one sickle beta globin gene. The carriers (trait) have no symptoms.
