Sickle cell vs beta thalassemia
WebThalassemia is a hemoglobinopathy that is among the most common inherited disorders of hemoglobin production. The normal adult hemoglobin molecule (Hb A) consists of 2 pairs of chains designated alpha and beta. Normal adult blood also contains ≤ 2.5% Hb A2 (composed of alpha and delta chains) and < 1.4% hemoglobin F (fetal hemoglobin), which ... WebIn a normal cell, the β-globin chains are coded by a total of two alleles.; Thus, there are two main forms of the disease. Beta-thalassemia minor (trait): one defective allele; Beta-thalassemia major (Cooley anemia): two defective alleles; Sickle cell beta thalassemia: a combination of one defective β-globin allele and one defective HbS allele
