Web25 Aug 2024 · Alpha and beta thalassemia are inherited hemoglobinopathies in which impaired production of one type of globin chain (alpha chains in alpha thalassemia; beta chains in beta thalassemia) causes an imbalance in the ratio between alpha and beta (or beta-like) chains, which is normally tightly controlled. Web9 Mar 2024 · Beta-thalassemia is largely caused by single base substitution, small deletions or insertions mutations within gene encoding beta-globin chain or its immediate flanking DNA sequence and rarely by gross deletions.
