- Overall Survival [ Time Frame: 100 Days, 1 Year and 3 Years ]Number of patients alive at designated timepoints after transplant.
- Overall Donor Engraftment [ Time Frame: Day 100 ]Number of patients with full donor chimerism (state in bone marrow transplantation in which bone marrow and host cells exist compatibly without signs of graft-versus-host rejection disease) by Day 100 post-transplant of at least 90%.
- Number of Patients With Grade II-IV Acute Graft-Versus-Host Disease [ Time Frame: Day 100 ]Number of patients who exhibited acute graft-versus-host disease by Day 100 post transplant. Graft-versus-host disease (GVHD) is a complication that can occur after a stem cell or bone marrow transplant in which the newly transplanted material attacks the transplant recipient's body. Grade I=mild, Grade II=moderate, Grade III=severe, Grade IV=life threatening.
- Number of Patients With Grade III-IV Acute Graft-Versus-Host Disease [ Time Frame: Day 100 ]
- Number of Patients With Chronic Graft-Versus-Host Disease [ Time Frame: 1 Year Post Transplant ]Number of patients who exhibited chronic graft-versus-host disease by 1 Year post transplant. Graft-versus-host disease (GVHD) is a complication that can occur after a stem cell or bone marrow transplant in which the newly transplanted material attacks the transplant recipient's body. Chronic GVHD is an extension of this syndrome.

Experimental: Treated Patients
All patients treated with protocol regimen (chemotherapy and surgery).
Procedure: Stem Cell Transplant
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).
Other Name: Bone marrow transplantDrug: Busulfan, Cyclophosphamide, Antithymocyte Globulin
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.
Other Name: Busulfex, Cytoxan, ATG
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.
