Beta thalassemia intermedia is a genetic blood disorder characterized by reduced production of hemoglobin, the protein in red blood cells that carries oxygen. Unlike beta thalassemia major, which presents with severe symptoms early in life, beta thalassemia intermedia has a milder clinical presentation. This condition results from mutations in the HBB gene, leading to an imbalance in the production of alpha and beta globin chains, causing ineffective erythropoiesis and varying degrees of anemia.
