Genetically modified viral vectors, such as adeno-associated viruses (AAVs), are successfully used in preclinical and clinical settings to deliver therapeutic genetic material and gene-editing tools to treat and correct genetic diseases.
The retrieved papers consistently demonstrate that viral vectors (such as AAVs) can be used to deliver gene therapies and gene-editing technologies to correct genetic mutations, restore biochemical homeostasis, and improve phenotypes in animal models and clinical applications of genetic diseases. There is no contradictory evidence in the retrieved literature.
