Gene therapy is a medical technology that aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells. [ 1 ] [ 2 ] [ 3 ]
The therapy known as Casgevy [9] works through editing a dysfunctional protein that interferes with creation of adult hemoglobin. This gene is known as the BCL11A, and when people have Beta thalassemia, their bodies do not make enough adult hemoglobin. Casgevy uses precise gene editing of stem cells, and reduces the activity of BCL11A.

Alipogene tiparvovec (Glybera): AAV-based treatment for lipoprotein lipase deficiency (no longer commercially available); Axicabtagene ciloleucel (Yescarta): treatment for large B-cell lymphoma [1]
The safety of gene therapy treatment is of utmost concern, especially during clinical trials when off-target modifications can block the further development of a candidate product. [57] Perhaps the most well-known example of modern gene therapy is CAR-T therapy, which is used for the treatment of B-cell lymphoma .
A chimeric mouse gene targeted for the agouti coat color gene, with its offspring. Gene targeting is a biotechnological tool used to change the DNA sequence of an organism (hence it is a form of Genome Editing). It is based on the natural DNA-repair mechanism of Homology Directed Repair (HDR), including Homologous Recombination. Gene targeting ...

A genetic vaccine (also gene-based vaccine) is a vaccine that contains nucleic acids such as DNA or RNA that lead to protein biosynthesis of antigens within a cell. Genetic vaccines thus include DNA vaccines, RNA vaccines and viral vector vaccines.
