The first attempt, an unsuccessful one, at gene therapy (as well as the first case of medical transfer of foreign genes into humans not counting organ transplantation) was performed by geneticist Martin Cline of the University of California, Los Angeles in California, United States on 10 July 1980.
Gene therapy was to restore some of the sight of mice with achromatopsia. The results were positive for 80% of the mice treated. [7] In 2010, gene therapy for a form of achromatopsia was performed in dogs. Cone function and day vision have been restored for at least 33 months in two young dogs with achromatopsia.
With the discovery of various types of immune-related disorders, there is a need for diversification in prevention and treatment. Developments in the field of gene therapy are being studied to be included in the scope of this treatment, but of course more research is needed to increase the positive results and minimize the negative effects of gene therapy applications.

The first human trials in the US for CRISPR gene editing are officially underway. A University of Pennsylvania in Philadelphia spokesman has confirmed to NPR that two cancer patients, one with ...
The gene to be inserted must be combined with other genetic elements in order for it to work properly. The gene can be modified at this stage for better expression or effectiveness. As well as the gene to be inserted most constructs contain a promoter and terminator region as well as a selectable marker gene.
Gene therapy [227] uses genetically modified viruses to deliver genes which can cure disease in humans. Although gene therapy is still relatively new, it has had some successes. It has been used to treat genetic disorders such as severe combined immunodeficiency, [228] and Leber's congenital amaurosis. [229]
Forever Friends, a spin-out company from Oxford University, hopes to dramatically expand the lifespan of dogs using new gene-editing technology. This startup wants to use gene-editing to extend ...
In retinal gene therapy, the most widely used vectors for ocular gene delivery are based on adeno-associated virus. The great advantage in using adeno-associated virus for the gene therapy is that it poses minimal immune responses and mediates long-term transgene expression in a variety of retinal cell types.
