Clonal Hematopoiesis Demonstrated by X-Linked DNA Polymorphisms after Allogeneic Bone Marrow Transplantation

Abstract
We analyzed DNA from peripheral-blood and marrow cells from 12 recipients of allogeneic bone marrow transplants to determine whether monoclonal but otherwise normal hematopoiesis occurs in such patients. All patients were being treated for various forms of leukemia or lymphoma.
