Gene Therapy

Gene Therapy

by Sophie G.

Gene therapy is replacing a defective gene with a new, working one.  It can cure diseases that are caused by mutated or defective genes.  The new gene is delivered into the cell by a virus that can break through the cell’s protections.  Some diseases that have been cured by gene therapy are blindness, color-blindness, and “Bubble-Boy” disease, a disease in which a child is born with no immune system because of mutated genes.  Scientists are working on curing cancer with gene therapy by using genes to turn blood cells into trackers and destroyers of cancer cells.  If I were a scientist, I would try to find out about more diseases caused by defective genes so that those diseases can be cured by gene therapy.  I would especially want to work on curing more kinds of cancer or deafness.
