Beta-thalassemia minor is a genetic blood disorder characterized by a reduced production of hemoglobin, the protein in red blood cells that carries oxygen. Individuals with this condition typically have one normal and one mutated copy of the HBB gene, leading to mild anemia. Most people with beta-thalassemia minor do not experience significant health issues and may not even be aware they have the condition. Diagnosis is often made through blood tests that reveal low hemoglobin levels and specific changes in red blood cell size and shape. While beta-thalassemia minor is generally mild, it is important for individuals to be aware of their carrier status, especially if planning to have children, as there is a risk of passing on more severe forms of beta-thalassemia.
