Al writes "Scientists have taken a step toward developing a cure for Duchenne muscular dystrophy (DMD) by successfully treating the condition in dogs using a novel genetic technique. The scientists used a method called exon skipping, which involves adding a genetic 'patch' to block transcription of a portion of the gene involved in DMD. This puts the remaining genetic sequence back in order, essentially creating a much less severe version of the condition. The scientists recorded some remarkable video footage showing the resulting improvements in several dogs with naturally-occurring DMD. More work is needed before the treatment can be given to humans, however, because DMD sufferers often have different genetic mutations."
