What is the primary focus of using gene therapy in clinical treatments?

The primary focus of using gene therapy in clinical treatments is to replace defective genes with functional ones. This approach addresses genetic disorders at their source by directly targeting the underlying genetic mutations. By introducing healthy copies of genes into a patient's cells, or by repairing the malfunctioning genes, gene therapy aims to restore normal function and ultimately improve health outcomes for individuals affected by genetic diseases. This targeted intervention allows for the possibility of correcting a variety of disorders, including inherited conditions, certain types of cancer, and viral infections. The idea is not to enhance physical traits or abilities, which is not the primary goal of medical therapy, nor is it to completely change the organism's genetic makeup or eliminate all genetic diseases simultaneously. Instead, it focuses specifically on rectifying specific genetic faults that lead to disease.
