Web18 apr. 2024 · In humans, alpha globin is expressed by two distinct loci, HBA1 and HBA2, with HBA2 expression predominating in red cell progenitors. However, gene expression of each specific locus in the vasculature, as well as the cellular localization and abundance of alpha globin in human vascular endothelium, is currently unknown. Methods WebAB - β-Thalassemia is one of the most common single-gene disorders. More than 100 mutations in or around the β-globin gene are known to cause decreased production of β-globin, which in turn leads to the excess accumulation of unstable α-globin chains, ineffective erythropoiesis, and shortened red-cell survival.
