We report successful bone marrow transplantation in an 11-year-old male with chronic myeloid leukemia from his HLA-identical sibling selected by preimplantation HLA testing. Because collection of cord blood failed, the transplantation was performed when the donor reached the age of 19 months, and sufficient bone marrow could be harvested safely. The patient was BCR/ABL negative at the time of transplantation after complete molecular response to imatinib. Currently, 16 months post-transplantation he is well and in complete molecular remission. This report describes preimplantation HLA-genotyping to deliver a matched sibling donor for successful transplantation of a malignant disorder.
