Gene therapy of inherited diseases requires long-term maintenance of the corrective transgene. Stable integration of the introduced DNA molecule into one of the host cell chromosomes is the simplest strategy for achieving this. However, genotoxicity resulting from random insertion of the transgene raises serious safety concerns that must be addressed if gene therapy is to enter the clinical mainstream. The following method makes use of the Rep integrase of adeno-associated virus to insert a transgene into the human AAVS1 site, a known "safe harbor" region within the human genome. This approach has the potential for application to novel gene therapy strategies for improved safety. In addition, with this method it is also possible to create cell lines carrying BAC transgenes in the AAVS1 site.
