The discovery of the subsarcolemmal muscle fiber protein dystrophin has, to a certain extent, replaced former nosological terms of Duchenne (DMD) and Becker (BMD) muscular dystrophies by the term dystrophinopathies.
Our results show that analysis of dystrophin expression is useful for the differential diagnosis of carriers of Xp21 dystrophy and autosomal muscular dystrophy, but that dystrophin expression does not correlate directly with the degree of clinical weakness.
Despite numerous reports about dystrophin alterations in Duchenne and Becker muscular dystrophies and dilated cardiomyopathy, the function of dystrophin gene promoters has not yet been completely elucidated.
Duchenne and Becker Muscular dystrophies (DMD/BMD) are allelic disorders caused by mutations in the dystrophin gene, which encodes a sarcolemmal protein responsible for muscle integrity.
An early onset muscular dystrophy with diaphragmatic involvement, early respiratory failure and secondary alpha2 laminin deficiency unlinked to the LAMA2 locus on 6q22.
Immunohistochemical and immunoblot screening for alpha-sarcoglycan protein deficiency was performed on all muscle biopsies from patients with a progressive muscular dystrophy of unknown aetiology and normal dystrophin.
These recent developments in the research concerning the function of the dystrophin-glycoprotein complex pave a way for the better understanding of the pathogenesis of muscular dystrophies.
The protein dystrophinis absent in the muscles of patients with Duchenne muscular dystrophy (DMD) as well as dystrophin-deficient mice with muscular dystrophy (mdx mice).
We investigated whether nicorandil promotes cardioprotection in human dystrophin-deficient induced pluripotent stem cell (iPSC)-derived cardiomyocytes and the muscular dystrophy mdx mouse heart.
Duchenne (DMD) and Becker (BMD) muscular dystrophy are allelic X-linked recessive diseases caused by a mutation in the dystrophin gene located on the short arm of chromosome X (Xp21).
We conducted a two-year pilot study to evaluate feasibility, reliability, and validity of various outcome measures, particularly the Motor Function Measure 32, in 33 subjects with COL6-RD and LAMA2-RD.
The cloning of the dystrophin gene has led to major advances in the understanding of the molecular genetic basis of Duchenne, Becker, and other muscular dystrophies associated with mutations in genes encoding members of the dystrophin-associated glycoprotein complex.
Loss-of-function mutations in the genes encoding dystrophin and the associated membrane proteins, the sarcoglycans, produce muscular dystrophy and cardiomyopathy.
This study emphasizes the clinical overlap between limb-girdle muscular dystrophy and dystrophinopathies, and reinforces the necessity of dystrophin protein and gene studies for the accurate clinical diagnosis of isolated cases of muscular dystrophy.
We describe a patient with somatic mosaicism of a point mutation in the dystrophin gene causing benign muscular dystrophy with an unusual asymmetrical distribution of muscle weakness and contractures.
Duchenne and Becker muscular dystrophies (DMD and BMD) are X-linked recessive neuromuscular disorders caused by mutations in the dystrophin gene affecting approximately 1 in 3,500 males.
This manuscript describes a methodology for introduction of corrective nucleic acids (CNAs) for the purpose of correcting the dystrophin gene (DMD ( mdx )) mutation responsible for muscular dystrophy in the mdx mouse model of human DMD by targeted corrective gene conversion (TCGC).
In particular, recent gene editing methods that led to the restoration of dystrophin expression in a canine model of muscular dystrophy could be applied to other canine models such as this before translation to humans.
