Summary : Genes are the building blocks of inheritance. Passed from parent to child, they contain instructions for making proteins. If genes dont produce the right proteins or dont produce them correctly, a child can have a genetic disorder. Gene therapy is an experimental technique that uses genes to treat or prevent disease. The most common form of gene therapy involves inserting a normal gene to replace an abnormal gene. Other approaches include - Swapping an abnormal gene for a normal one - Repairing an abnormal gene - Altering the degree to which a gene is turned on or off Although there is much hope for gene therapy, it is still experimental.
