What does gene therapy aim to accomplish?

Gene therapy aims to alter genes to treat or prevent disease by addressing the root cause of genetic disorders at the molecular level. This technique involves modifying or replacing defective genes to correct the underlying issues associated with various illnesses. By introducing healthy genes, correcting abnormal genes, or even inactivating genes that are functioning improperly, gene therapy seeks to restore normal cellular function and, in many cases, provide long-term solutions to genetic conditions.

While increasing lifespan or enhancing physical attributes may seem appealing, these are not the primary objectives of gene therapy. Additionally, gene therapy does not aim to completely replace traditional medicine; instead, it serves as a complementary approach that can work alongside existing treatments to improve patient outcomes. The primary focus remains on the treatment and prevention of diseases through genetic modification.
