Web9 apr. 2024 · Summary. The alpha (HBA) and beta (HBB) loci determine the structure of the 2 types of polypeptide chains in adult hemoglobin, Hb A. The normal adult hemoglobin tetramer consists of two alpha chains and two beta chains. Mutant beta globin causes sickle cell anemia. Absence of beta chain causes beta-zero-thalassemia. WebPeople with all types of SCD inherit the gene for hemoglobin S from 1 parent and a gene for another type of hemoglobin from 1 parent. Hemoglobin S (also called sickle hemoglobin) is the most common type of abnormal hemoglobin. It has a mutation that causes it to form rigid strands that make red blood cells stiff and sickle-shaped. 1 Web12 jan. 2016 · The exact number of hemoglobin variants is currently specified in the Database of Human Hemoglobin Variants and Thalassemias (HbVar) as 1212, or 1635 when thalassemia mutations are added.
