Duchenne and Becker muscular dystrophies are rare diseases that receive limited attention in our field. The objective of this study was to implement the Multiplex Ligation-dependent Probe Amplification technique (MLPA) and to demonstrate that it has advantages over the Multiplex Polymerase Chain Reaction (Multiplex PCR) technique. Samples from 40 individuals with a presumptive diagnosis of Duchenne and Becker muscular dystrophies were analyzed: first by Multiplex PCR and then by MLPA. Fifteen individuals with causal deletions were detected with Multiplex PCR, while the MLPA technique was able to diagnose 21 individuals, four duplications, and 17 deletions. In conclusion, the MLPA technique can detect mutations of the exon deletion and duplication type, yielding a larger number of molecular diagnoses due to alterations in the DMD gene.

Dysphagia is reported in patients with Duchenne or Becker muscular dystrophy. Our clinical experience suggests that, compared to Duchenne patients, impaired mastication and swallowing occur early in B...
Absent or truncated dystrophin in Duchenne (DMD) and Becker (BMD) muscular dystrophies results in impaired vasodilatory pathways and exercise induced muscle ischemia. Here, we used power Doppler sonog...
Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are characterized by muscle wasting leading to loss of ambulation in the first or third decade, respectively. In DMD, the lack of ...
The dystrophinopathies are among the most common neuromuscular conditions, and they include Duchenne and Becker muscular dystrophies. This article reviews the epidemiology, clinical manifestations, ge...
Duchenne/Becker muscular dystrophy (DMD/BMD) is the most common genetic neuromuscular disease in children, resulting from a defect in the DMD gene located on Xp21.2. The new emerging treatment using e...
This study evaluates the function of the heart in young patients with muscular dystrophy type Duchenne or Becker. Participants have their hearts examined at regular intervals by ultrasound...
Data on preventive therapy in Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) affected individuals without cardiac involvement are very limited and currently lacking ...

Duchenne's Muscular Dystrophy and Becker Dystrophy, hereafter DMD and BMD, is a serious and progressive disease that affects 1 in 3,500-6,000 males born alive. Scale 6-minute walking test,...
Dystrophinopathy is a term of X-linked recessive genetic disease, including Duchenne Muscular Dystrophy, Becker Muscular Dystrophy, and the X-linked dilated cardiomyopathy. The aim of this...
A muscle protein localized in surface membranes which is the product of the Duchenne/Becker muscular dystrophy gene. Individuals with Duchenne muscular dystrophy usually lack dystrophin completely while those with Becker muscular dystrophy have dystrophin of an altered size. It shares features with other cytoskeletal proteins such as SPECTRIN and alpha-actinin but the precise function of dystrophin is not clear. One possible role might be to preserve the integrity and alignment of the plasma membrane to the myofibrils during muscle contraction and relaxation. MW 400 kDa.
Deficiencies or mutations in the genes for the SARCOGLYCAN COMPLEX subunits. A variety of phenotypes are associated with these mutations including a subgroup of autosomal recessive limb girdle muscular dystrophies, cardiomyopathies, and respiratory deficiency.
An X-linked recessive muscle disease caused by an inability to synthesize DYSTROPHIN, which is involved with maintaining the integrity of the sarcolemma. Muscle fibers undergo a process that features degeneration and regeneration. Clinical manifestations include proximal weakness in the first few years of life, pseudohypertrophy, cardiomyopathy (see MYOCARDIAL DISEASES), and an increased incidence of impaired mentation. Becker muscular dystrophy is a closely related condition featuring a later onset of disease (usually adolescence) and a slowly progressive course.

A disorder characterized by multiple, wide spread cutaneous cysts that often become inflamed and rupture. It is caused by the same mutations in the gene coding for KRT-17 that are causative mutations for Pachyonychia congenita, Type 2. Natal teeth involvement is sometimes associated with steatocystoma multiplex.
A membrane protein that contains multiple C2 DOMAINS. It is highly expressed in skeletal muscle and functions as a calcium ion sensor in SYNAPTIC VESICLE-PLASMA MEMBRANE fusion, as well as in SARCOLEMMA repair following mechanical stress. Mutations in the dysferlin (DYSF) gene are associated with several hereditary MUSCULAR DYSTROPHIES.
Polymerase Chain Reaction (PCR)
PCR (Polymerase Chain Reaction) uses the ability of DNA polymerase (enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two ident...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
