BACKGROUND Dystrophin is the product of the gene that is mutated in Duchenne muscular dystrophy (DMD), a progressive neuromuscular disease for which no treatment is available. Mice carrying a mutation in the gene for dystrophin (mdx mice) display only a mild phenotype, but it is aggravated when combined with a mutation in the MyoD gene. The nematode worm Caenorhabditis elegans has a dystrophin ...

OBJECTIVE Duchene and Becker Muscular Dystrophy (DMD/ BMD) are x-linked disorders that both are the result of heterogeneous mutations in the dystrophin gene. The frequency and distribution of dystrophin gene deletions in DMD/ BMD patients show different patterns among different populations. This study investigates the deletion rate, type, and distribution of this gene in the Azeri Turk populati...

Duchenne muscular dystrophy (DMD) is a severe progressive muscular disorder caused by reading frame disrupting mutations in the DMD gene, preventing the synthesis of functional dystrophin. As dystrophin provides muscle fiber stability during contractions, dystrophin negative fibers are prone to exercise-induced damage. Upon exhaustion of the regenerative capacity, fibers will be replaced by fib...

An inherited dystrophin deletion without muscle weakness Deletions of the dystrophin gene are known to be present in approximately 60 to 70%6 of Duchenne (DMD) and Becker (BMD) patients. We describe a boy and his maternal grandfather who both have raised creatine kinase levels and an identical deletion including exons 14-18 of the dystrophin gene but no muscle weakness. Muscle histology is norm...

Duchenne muscular dystrophy is the most prevalent and severe form of human muscular dystrophy. Investigations into the molecular basis for Duchenne muscular dystrophy were greatly facilitated by seminal studies in the 1980s that identified the defective gene and its major protein product, dystrophin. Biochemical studies revealed its tight association with a multi-subunit complex, the so-named d...

The protein dystrophin, normally found on the cytoplasmic surface of skeletal muscle cell membranes, is absent in patients with Duchenne muscular dystrophy as well as mdx (X-linked muscular dystrophy) mice. Although its primary structure has been determined, the precise functional role of dystrophin remains the subject of speculation. In the present study, we demonstrate that dystrophin-deficie...

Duchenne Muscular Dystrophy (DMD) is an X-linked inherited neuromuscular disorder due to mutations in the dystrophin gene. It is characterized by progressive muscle weakness and wasting due to the absence of dystrophin protein that causes degeneration of skeletal and cardiac muscle. We present a case of Duchenne muscular dystrophy induced myocardial damage manifesting as acute myocardial infarc...

Duchenne muscular dystrophy (DMD) is a progressive degenerative lethal muscle disease. A significant proportion of DMD affected children suffer also from mental retardation. The rod shaped protein, dystrophin, which is absent from or defective in the muscle of DMD patients, binds to a number of membrane associated proteins (known collectively as dystrophin associated proteins [DAPs]). The level...

Background: Duchenne muscular dystrophy (DMD) is caused by a mutation in the dystrophin gene and most common form of childhood-onset affecting approximately 1 3500 newborn boys. The disease invariably progressive patients with DMD exhibit signs muscle weakness before 5 years age. Loss ability to walk usually occurs between 10 13 years. Despite all advances management treatment over last decades...

Human artificial chromosome (HAC) has several advantages as a gene therapy vector, including stable episomal maintenance that avoids insertional mutations and the ability to carry large gene inserts including the regulatory elements. Induced pluripotent stem (iPS) cells have great potential for gene therapy, as such cells can be generated from the individual's own tissues, and when reintroduced...
