Human mutation

Antisense-mediated exon skipping aiming for reading frame restoration is currently a promising therapeutic application for Duchenne muscular dystrophy (DMD). This approach is mutation specific, but as the majority of DMD patients have deletions that cluster in hotspot regions, the skipping of a small number of exons is applicable to relatively large numbers of patients. ⋯ Exon 51 skipping, which is being tested in clinical trials, would be applicable to the largest group (13%) of all DMD patients. Further research is needed to determine the functionality of different in-frame dystrophins and a number of hurdles has to be overcome before this approach can be applied clinically.
