Germline Gene Transfer. Gene transfer represents a relatively new possibility for the treatment of rare genetic disorders and common multifactorial diseases by changing the expression of a person's genes. Typically gene transfer involves using a vector such as a virus to deliver a therapeutic gene to the appropriate target cells.

This technique (which is often used in connection with in vitro fertilization (IVF)), may be used in humans or in animals, in which situations the goals may vary.
