194th ENMC international workshop. 3rd ENMC workshop on exon skipping: towards clinical application of antisense-mediated exon skipping for Duchenne muscular dystrophy 8-10 December 2012, Naarden, The Netherlands.
TL;DR: The topic of this workshop was on ‘Streamlining the development path of exon skipping compounds’ and followed the formula of similar workshops held in 2004 and 2007, which focused on intramuscular administration of antisense oligonucleotides.

TL;DR: The junction sequence cloned by PCR walking abolished the splicing enhancer activity of the upstream intron in a chimeric doublesex gene pre-mRNA in vitro splicing and indicated that the junction sequence was a splicing silencer that induced upstream exon 44 skipping.

Recent developments in the treatment of Duchenne muscular dystrophy and spinal muscular atrophy
Wendy K.M. Liew,Peter B. Kang +1 more
TL;DR: This work has shown that utilizing a probabilistic approach to treatment of Duchenne muscular dystrophy and spinal muscular atrophy is a viable option for both quality of life and life expectancy for affected individuals.
Journal ArticleDOI
The rapidly evolving state of gene therapy.
TL;DR: An overview of the state of gene therapy is provided by discussing where the field stands with respect to the different gene therapy vector platforms and the types of therapies that are available.

Dystrophin: The protein product of the duchenne muscular dystrophy locus
TL;DR: The identification of the mdx mouse as an animal model for DMD has important implications with regard to the etiology of the lethal DMD phenotype, and the protein dystrophin is named because of its identification via the isolation of the Duchenne muscular dystrophy locus.
