Funded Activity Summary

RPE65 is a gene that is found exclusively within the retina. At the moment the exact role of RPE65 is not known, however recent research has shown that mutations in the RPE65 gene have been found in a number of inherited retinal dystrophies (these dystrophies include Leber congenital amaurosis and autosomal recessive retinitis pigmentosa). It therefore appears that a functional, non-mutated RPE65 gene is essential for normal vision. A mouse model of RPE65-related retinal dystrophies has been recently developed, by producing a RPE65 knockout mouse breed in which the mouse's RPE65 gene has been mutated into an inactive form. Research on these mice have shown that they develop retinal dystrophies very similar to those seen in patients with mutated RPE65 genes. We propose to use these RPE65 knockout mice to test potential methods for treating the RPE65-related retinal dystrophies in patients. In particular, we will study the potential of using gene therapy to treat these diseases. The project will involve delivering a new, functional RPE65 gene to the retinas of the RPE65 knockout mice. The new, functional RPE65 gene will then replace the inactive, mutated RPE65 gene within the mouse retinas, an action that we predict will be able to stop these mice developing retinal dystrophy. Performing such a study will allow us to improve our understanding of the RPE65-related retinal dystrophies, and provide an indication of whether they can be treated with gene therapy.
