|title=Long-term and age-dependent restoration of visual function in a mouse model of [[CNGB3]]-associated achromatopsia following gene therapy.

|abstract=Mutations in the [[CNGB3]] gene account for >50% of all known cases of achromatopsia. Although of early onset, its stationary character and the potential for rapid assessment of restoration of retinal function following therapy renders achromatopsia a very attractive candidate for gene therapy. Here we tested the efficacy of an rAAV2/8 vector containing a human cone arrestin promoter and a human [[CNGB3]] cDNA in [[CNGB3]] deficient mice. Following subretinal delivery of the vector, [[CNGB3]] was detected in both M- and S-cones and resulted in increased levels of [[CNGA3]], increased cone density and survival, improved cone outer segment structure and normal subcellular compartmentalization of cone opsins. Therapy also resulted in long-term improvement of retinal function, with restoration of cone [[ERG]] amplitudes of up to 90% of wild-type and a significant improvement in visual acuity. Remarkably, successful restoration of cone function was observed even when treatment was initiated at 6 months of age; however, restoration of normal visual acuity was only possible in younger animals (e.g. 2-4 weeks old). This study represents achievement of the most substantial restoration of visual function reported to date in an animal model of achromatopsia using a human gene construct, which has the potential to be utilized in clinical trials.
