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 ]

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 gene must then be isolated and incorporated, along with other genetic elements, into a suitable vector. This vector is then used to insert the gene into the host genome, creating a transgenic or edited organism. The ability to genetically engineer organisms is built on years of research and discovery on gene function and manipulation.
The first retinal gene therapy to be approved by the FDA was Voretigene neparvovec in 2017, which treats Leber's congenital amaurosis, a genetic disorder that can lead to blindness. These treatments also use subretinal injections of AAV vector and are therefore foundational to research in gene therapy for color blindness. [2] [3]
In gene therapy a gene that is intended for delivery is packaged into a replication-deficient viral particle to form a viral vector. [29] Viruses used for gene therapy to date include retrovirus, adenovirus, adeno-associated virus and herpes simplex virus. However, there are drawbacks to using viruses to deliver genes into cells.
