Abstract
Long-term correction of genetic diseases requires permanent integration of therapeutic genes into chromosomes of affected cells. Retroviral vectors are the most widely used delivery vehicles because of their efficiency and precision of integration. However, retroviral integration can take place at a variety of chromosomal sites, and examples have been reported of integration of therapeutic vectors activating oncogenes and causing cancer in patients. This issue of the JCI presents three articles that update successful human gene therapy trials and furthermore evaluate the sites of integration in cells from treated patients, including samples from individuals experiencing serious adverse events following therapy (see the related articles beginning on pages 2225, 2233, and 2241).

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
