Genes are the "instruction manual" for our bodies, and they contain a chemical called DNA. Gene therapy has a huge impact on our health. Each unique gene has a DNA sequence that is "normal" for the type of gene. This is called a gene variant. They can sometimes pass from one parent to the next. This is where gene therapy comes in. Gene therapy has many benefits that allow us to modify our DNA. This is where the goal is to restore normal DNA. This could mean replacing the defective gene with a healthy one. This could also mean that defective genes are made inactive. This would indicate that a new gene has entered the body to treat the health condition. In 1990, the first study of gene therapy was completed. We...
