Part Description

LP231879-0   HBA2 gene alpha 3.7kb triplication
A chromosome with a triple alpha-globin loci, counterpart of the -alpha 3.7 deletion, may be present in patients with slight HbA2 enzyme increase and in association with beta-thalassemias. The alpha-globin 3.7kb triplication is an important modulator of the severity of beta-thalassemia trait or beta-thalassemia intermedia, causing globin chain imbalance and therefore exacerbating the phenotypic severity of beta-thalassemia. Co-inheritance of triplicated alpha-globin in beta-heterozygotes often leads to more significant anemia, splenomegaly, more pronounced red cell abnormalities, presence of circulating normoblasts, higher hemoglobin F concentrations, and presence of inclusion bodies in erythroblasts.
