Summary:

      The goal of this clinical research study is to learn about the safety of giving a stem cell
      transplant from a tissue-mismatched donor, followed by cyclophosphamide, to patients with
      certain types of blood disorders or blood cancers. Melphalan, thiotepa, and fludarabine will
      also be given before the transplant.

      Researchers will study the health status of these patients at 3 months after the transplant.
