Faulty genes can be deactivated or silenced by the gene inhibition approach. It suppresses a gene.

A new protein-coding gene is inserted into a target cell by gene augmentation. This approach is popular for treating monogentic disease.

When a gene is introduced directly into the body or tissue by intravenous way. This approach is tissue specific.
