Laparoscopic watson fundoplication is effective and durable in children with gastrooesophageal reflux.

Gastroesophageal reflux (GOR) affects 2-8% of children over 3 years of age and is associated with significant morbidity. The disorder is particularly critical in neurologically impaired children, who have a high risk of aspiration. Traditionally, the surgical antireflux procedure of choice has been Nissen's operation.

Adenovirus-based targeting in myoblasts is hampered by nonhomologous vector integration.

Chromosomal correction of dystrophin gene mutations is a most desirable therapeutic solution for Duchenne muscular dystrophy, as it allows production of the full-length dystrophin under the control of locus-specific promoters. Here we explored gene targeting in conditionally immortal mouse dystrophin-deficient myoblasts. We constructed an adenoviral vector for the correction of the mdx mutation, containing 6.

Genomic definition of a pure intronic dystrophin deletion responsible for an XLDC splicing mutation: in vitro mimicking and antisense modulation of the splicing abnormality.

We characterised a dystrophin gene rearrangement in a previously described family with X-linked dilated cardiomyopathy and we demonstrated that it represents an 11 kb deletion occurring within intron 11. This unique deletion joined two physiologically distant intronic regions and brought adjacent two cryptic splice sites, generating a 159 bp sequence recognised as a novel alternative exon and spliced into the dystrophin transcript. Comparative analysis of the intronic region involved in the breakpoint revealed the presence of a LINE1 element (L1P_MA2), containing a 5' unconventional region (L1M1_5).

Bifunctional antisense oligonucleotides provide a trans-acting splicing enhancer that stimulates SMN2 gene expression in patient fibroblasts.

The multiplicity of proteins compared with genes in mammals owes much to alternative splicing. Splicing signals are so subtle and complex that small perturbations may allow the production of new mRNA variants. However, the flexibility of splicing can also be a liability, and several genetic diseases result from single-base changes that cause exons to be skipped during splicing.
