Donald Kohn, MD
Dr. Donald Kohn has served as an attending physician in the pediatric bone marrow transplant program for more than 30 years. His research focuses on the development of new methods to treat genetic diseases of blood cells by gene modification of hematopoietic stem cells. Kohn's group was the first (and still the only one) to perform a clinical trial with gene transfer to umbilical cord blood CD34+ cells for a genetic disorder (ADA-SCID in 1993) and the first in the U.S. to initiate a clinical trial of gene therapy for pediatric AIDS using bone marrow stem cells.
Kohn's laboratory is currently focused on two main areas: 1) the development and clinical evaluation of improved methods for gene therapy of genetic diseases of blood cells targeting hematopoietic stem cells, especially ADA-deficient SCID and sickle cell disease, and 2) pre-clinical studies focused on the use of lentiviral vectors for gene addition to stem cells and site-specific nucleases (ZFNs, CRISPRs) for gene correction by homologous recombination.
His lab is currently performing clinical trials using lentiviral vectors for ADA-deficient SCID, Sickle Cell Disease and X-linked Chronic Granulomatous Disease. In addition, Kohn's group is participating as one of three U.S. sites for an NIAID-funded clinical trial of gene therapy for X-SCID.
