Gene therapy primarily aims to correct what?

Gene therapy primarily aims to correct defective genes causing genetic disorders. This innovative approach involves modifying or replacing faulty genes to treat or prevent diseases that are rooted in genetic abnormalities. The underlying principle is that many diseases emerge due to mutations or malfunctions within specific genes. By addressing these genetic defects directly, gene therapy seeks to restore normal function at the cellular level, ultimately alleviating or curing the disorder.

For instance, in conditions such as cystic fibrosis or muscular dystrophy, the therapy targets the specific genes that are responsible for the disease phenotype. By correcting these genetic issues, patients can experience significant improvements in their health and quality of life.

Other options, while important health considerations, do not align with the primary goals of gene therapy. Environmental factors, nutritional deficiencies, and physical injuries represent different categories of health challenges that are typically managed through other medical interventions and therapies, rather than through genetic modification or correction. This distinction is crucial in understanding the specialized focus of gene therapy within the realm of medical interventions.
