Non-Ambulant Duchenne Patients Theoretically Treatable by Exon 53 Skipping have Severe Phenotype

BACKGROUND Exon skipping therapy is an emerging approach in Duchenne Muscular Dystrophy (DMD). Antisense oligonucleotides that induce skipping of exon 51, 44, 45, or 53 are currently being evaluated in clinical trials. These trials were designed on the basis of data available in general DMD population. OBJECTIVES Our objective was to compare the clinical and functional statuses of non-ambulan...

Exon skipping therapy for Duchenne muscular dystrophy.

Duchenne muscular dystrophy (DMD) is caused mostly by internal deletions in the gene for dystrophin, a protein essential for maintaining muscle cell membrane integrity. These deletions abrogate the reading frame and the lack of dystrophin results in progressive muscle deterioration. DMD patients experience progressive loss of ambulation, followed by a need for assisted ventilation, and eventual...

AON-Mediated Exon Skipping for Duchenne Muscular Dystrophy

Less is more: therapeutic exon skipping for Duchenne muscular dystrophy.

www.thelancet.com/neurology Vol 8 October 2009 873 Duchenne muscular dystrophy (DMD) is a lethal Xlinked progressive muscle-wasting disease caused by premature truncation of the translation of DMD mRNA into dystrophin. Owing to improved respiratory support and treatment with steroids, patients can now survive into early adulthood, which is one or two decades longer than they could survive witho...

Prolonged Ambulation in Duchenne Patients with a Mutation Amenable to Exon 44 Skipping.

Duchenne muscular dystrophy has a severe disease course, though variability exists. Case reports suggest a milder disease course of patients amenable to exon 44 skipping. In this study, we analyzed this and show that age at wheelchair dependence in patients with a dystrophin deletion requiring exon 44 skipping is postponed compared to patients with a deletion skippable by exon 45, 51 and 53 (10...
