A clinical trial is already being planned with patients being recruited within the next couple of years.
The gene therapy achieved remarkable results in dogs with muscular dystrophy - paving the way for clinical trials in humans.
The UK and French team corrected a mutation in a dozen Golden Retrievers that had developed the disorder.
Professor George Dickson, of the University of London in Egham, Surrey, said: ““There are ongoing animal tests to be done to enable a clinical trial.”
Prof Dickson added: “We foresee patient recruitment over the next 12 to 24 months.”
