Hi Asma,
The cap +1 (A-C) mutation is a silent mutation that when combined with other thal mutations in minors will produce a thal intermedia.
Her Hb is somewhat borderline right now and you do want to see it higher. Because of her high HbF% she may be a good candidate for fetal hemoglobin stimulation. This is done by using natural products like wheatgrass and the supplement resveratrol, and by use of the drug hydroxyurea. You should also establish good eating habits in her that rely on nutritious foods. A good multivitamin without iron would also be suggested at this age.
Only time will tell if she ever needs transfusion. I think diet and supplements can help her avoid that.
