beta thalasemia and sickle cell may be candidate of BMT?

My son is 20 months and is beta thal and sickle cell .he has
 taken hydroxyurea and folic acid plus lots of vitamins last 8 months.
He is currently doing fine and much active. We have yet to find out the effects
Of HU on her hb which is 8 to 9 last one year consistently.

But my question is should we be thinking of BMT . We want to
Make this decision before time runs out on us and it becomes
Too risky for her. Plz tell us the right treatments.
HBF was 35.7 % and HBA was at 17.3 % HB S 42.9 and HB A2 4.1 % and no any blood transfusion ever.

You should talk to a bone marrow transplant center about this. Many centers will not do BMT for patients who are not transfusion dependent.

Dear BMT suitable for my son?
