Complications from treatment, such as mechanical ventilation and tracheotomy procedures, are also a concern. Muscle fibers undergo necrosis and are ultimately replaced with adipose and connective tissue. Search Bing for all related images.

Duchenne muscular dystrophy – Wikipedia

Color blindness red and green, but not blue Ocular albinism 1 Norrie disease Choroideremia Other: Due to defects in this assembly, contraction of the muscle leads to disruption of the outer membrane of the muscle cells and eventual weakening and wasting of the muscle.

Hunter syndrome Purine—pyrimidine metabolism: Many mutations are responsible for DMD, and some have not been identified, so genetic testing only works when family members with DMD have an identified mutation.


Duchenne muscular dystrophy Microscopic image of the calf muscle from a person with Duchenne muscular dystrophy. Haemophilia A Haemophilia B X-linked sideroblastic anemia. Dystrophin is part of a complex structure involving several orogressives protein components.

The ventilator may require an invasive endotracheal or tracheotomy tube through which air is directly delivered, but for some people, noninvasive delivery through a face mask or mouthpiece is sufficient.

Cardiomyopathy particularly dilated progressivws is common, but the development of congestive heart failure or arrhythmia irregular heartbeat is only occasional.

Microscopic image of the calf muscle from a person with Duchenne muscular dystrophy. Miyoshi myopathy, one of the distal muscular dystrophies, causes initial weakness in the calf muscles, and is caused by defects in the same gene responsible for one form of limb-girdle muscular dystrophy.

This content does not have an Arabic version. Because of special circumstances present in Utah a study has been initiated which has as its object the investigation of diseases of muscle, especially progressive muscular dystrophy. Dyztrophies X-linked recessiveautosomal recessiveor autosomal dominant [2].

Fathers cannot pass X-linked traits on to their sons, so the mutation is transmitted by the mother. It becomes harder and harder for the boy to walk; his ability to walk usually completely disintegrates between the dystrohpies the boy is 9 to 12 years of age.

Symptoms usually appear before age six and may appear in early infancy. Medical geneticspediatrics. We extended this comparison to the single mutation patients and we found the same results.

Other tests that can be done are chest X-rayechocardiogramCT scanand magnetic resonance image scan, which via a magnetic field can produce images whose detail helps diagnose muscular dystrophy. Inhe gave an account of 13 other affected children.


A year later, he presented photos of his patient in his Album de photographies pathologiques. Related Topics in Motor Disorders. DNA testing confirms the diagnosis in most cases.

Clinical features and diagnosis of Duchenne and Becker muscular dystrophy. However, it may be possible, through advancements in technology, to use this technique to develop therapies for DMD in the future. The next leading cause of death is cardiac-related conditions such as heart failure brought on by dilated cardiomyopathy. Less than 30 years ago, the identification of the genetic basis of Duchenne muscular dystrophy opened a new era.
