Does HEmoglobin mutation cause disease

Yes, hemoglobin mutations can cause diseases, most notably sickle cell disease and various types of thalassemia. These mutations can alter the structure and function of hemoglobin, leading to impaired oxygen transport and various complications. In sickle cell disease, for instance, abnormal hemoglobin causes red blood cells to become rigid and sickle-shaped, leading to blockages in blood vessels and pain. Thalassemias result in reduced hemoglobin production, leading to anemia and other health issues.
