What is a key application of gene therapy?

Gene therapy primarily aims to treat or correct genetic disorders by altering or manipulating genes to improve health outcomes. This is achieved by introducing, removing, or altering genetic material within a patient's cells. By directly addressing the root causes of genetic disorders—such as mutations that lead to diseases like cystic fibrosis, muscular dystrophy, or certain types of cancer—gene therapy can potentially lead to permanent changes in cellular function and benefit patients in a substantial way.

In contrast, enhancing athletic performance, producing hormone supplements, and preventing aging do not directly fall under the intended applications of gene therapy, which is firmly rooted in addressing genetic abnormalities and their related health issues. Each of these other options may involve different biological processes or interventions, but they do not capture the core purpose of gene therapy.
