A patient with beta-thalassemia may be asymptomatic or not, depending on what genes have been inherited. The severity of the anemia correlates with complications.
Parameters:
(1) severity of anemia
(2) mean cell volume (MCV)
(3) splenomegaly
(4) bone lesions
(5) transfusion requirements
(6) iron overload
(7) symptoms
