Official Title: Treatment of High Risk, Inherited Lysosomal and Peroxisomal Disorders by Reduced-Intensity Hematopoietic Cell Transplantation and Low-Dose Total Body Irradiation With Marrow Boosting by Volumetric-Mod

Brief Summary: This study is designed to test the ability to achieve donor hematopoietic engraftment while maintaining low rates of transplant-related mortality (TRM) in patients with high-risk lysosomal and peroxisomal disorders using a novel conditioning regimen for hematopoietic cell transplantation (HCT). After a reduced-intensity conditioning regimen using volumetric-modulated arc therapy (VMAT)-delivered low-dose total body irradiation (TBI) with highly conformal marrow boosting, patients will be transplanted using either a related or unrelated allograft. The cell source may be marrow, peripheral blood or cord blood based on donor availability.
