Beta-thalassemia minor is characterized by which of the following?

• A. Mild symptoms and signs
• B. Severe anemia
• C. No symptoms
• D. Requires regular transfusions

Answer: (A)

Beta-thalassemia minor is a carrier state where beta-globin production is reduced. This typically causes only a mild decrease in hemoglobin and often little to no noticeable symptoms; many individuals feel fine and show only subtle lab findings like mild microcytosis. Because the defect is limited to one gene, there isn’t the severe anemia that would require regular transfusions, which is characteristic of beta-thalassemia major. So the common clinical picture is mild symptoms and signs, making that option the best choice.
