Your red … WebAlpha thalassemia is caused by a mutation (or change) in the gene (or instructions) that controls how much alpha globin to make. Hemoglobin is made of two alpha globins and two beta globins. In alpha thalassemia, the body makes less alpha globin than beta globin because of the gene mutation. The imbalance in alpha and beta globin causes anemia ...
