Brief summary:
The purpose of this study is to determine the safety and engraftment of donor hematopoietic cells using this conditioning regimen in patients undergoing a hematopoietic (blood forming) cell transplant for an inherited metabolic storage disease.

Detailed description:
Prior to transplantation, subjects will receive Busulfan intravenously (IV) via the Hickman line four times daily for 4 days, Cyclophosphamide intravenously via the Hickman line once a day for 4 days, and Anti-Thymocyte Globulin (ATG) intravenously (IV) via the Hickman line twice daily for three days before the transplant. These three drugs are being given to subjects to help the new marrow "take" and grow.

On the day of transplantation, the donor's hematopoietic cells will be transfused via central venous catheter.

After hematopoietic cell transplant, subjects will then receive two drugs, cyclosporin and either methylprednisolone or Mycophenolate Mofetil (MMF). Cyclosporin and methylprednisolone or MMF are given to help prevent the complication of graft-versus-host disease and to decrease the chance that the new donor cells will be rejected.

Arms:
arm 1: All patients treated with protocol regimen (chemotherapy and surgery).

Interventions: intervention 1: Stem Cell Transplant intervention 2: Busulfan, Cyclophosphamide, Antithymocyte Globulin
Intervention descriptions: intervention 1: The purpose of hematopoietic cell transplantation is to introduce hematopoietic cells from a normal donor that contains an enzyme able to get rid of the substances that have accumulated in the body of patients with storage diseases. Hematopoietic cells can come from bone marrow, peripheral blood (i.e., the blood circulating in our body's blood vessels) or umbilical cord blood (i.e., blood taken from the umbilical cord after a baby is born and umbilical cord is cut). intervention 2: Subjects will receive BUSULFAN intravenously (IV)- patients \< or= 12 kg 1.1 mg/kd/dose IV every 6 hours for 16 doses; patients \> 12kg 0.8 mg/kg/dose IV every 6 hours for 16 doses - via the Hickman line four times daily for 4 days, CYCLOPHOSPHAMIDE intravenously (50 mg/kg/day IV over 2 hours) via the Hickman line once a day for 4 days, and ANTI-THYMOCYTE GLOBULIN IV (15 mg/kg/day over 2 hours) via the Hickman line twice daily for three days before the transplant. These three drugs are being given to help the new marrow "take" and grow. METHYLPREDNISOLONE will be given as a pre-medication for the ATG.
