Splicing-correcting therapeutic approaches for retinal dystrophies: where endogenous gene regulation and specificity matter.

Splicing is an important and highly regulated step in gene expression. The ability to modulate it can offer a therapeutic option for many genetic disorders. Antisense-mediated splicingcorrection approaches have recently been successfully exploited for some genetic diseases, and are currently demonstrating safety and efficacy in different clinical trials. Their application for the treatment of retinal dystrophies could potentially solve a vast panel of cases, as illustrated by the abundance of mutations that could be targeted and the versatility of the technique. In this review, we will give an insight of the different therapeutic strategies, focusing on the current status of their application for retinal dystrophies.
