Therapy for patients with congenital sideroblastic anaemia has been limited to blood transfusions and chelation. Three children with congenital sideroblastic anaemia (SA) who were blood transfusion dependent underwent stem cell transplantation (SCT) from matched sibling donors. Conditioning consisted of cyclophosphamide 50 mg/kg/d for 4 d, busulphan 4 mg/kg/d for 4 d and anti-thymocyte globulin (ATG) 30 mg/kg for four doses pretransplant. Graft-versus-host disease (GVHD) prophylaxis was with cyclosporin A and methotrexate. All patients engrafted, and are alive and transfusion independent. SCT can be curative for patients with SA.
