The correction of genetic errors associated with
disease in animals suggests that gene editing has potential
applications in gene therapy for humans. Gene therapy is
the introduction of a normal gene into an individual’s genome
in order to repair a mutation that causes a genetic disease.
When a normal gene is inserted into a mutant nucleus, it most
likely will integrate into a chromosomal site different from the
defective allele. Although this may repair the mutation, a new
mutation may result if the normal gene integrates into another
functional gene. If the normal gene replaces the mutant allele,
there is a chance that the transformed cells will proliferate and
produce enough normal gene product for the entire body to be
restored to the undiseased phenotype.
