Muscular Dystrophy The muscular dystrophies (MD) are a group of more than 30 genetic diseases characterized by progressive weakness and degeneration of the skeletal muscles that control movement. Some forms of MD are seen in infancy or childhood, while others may not appear until middle age or later.

Duchenne Muscular Dystrophy (DMD) Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness. It is one of nine types of muscular dystrophy. DMD is caused by an absence of dystrophin, a protein that helps keep muscle cells intact.

Symptoms include weakness and wasting of shoulder, upper arm, and shin muscles; joint deformities are common; progression is slow; sudden death may occur from cardiac problems.

Types of Muscular Dystrophy and Neuromuscular Diseases Muscular dystrophy is a group of inherited diseases that are characterized by weakness and wasting away of muscle tissue, with or without the breakdown of nerve tissue.There are nine types of muscular dystrophy, with each type involving an eventual loss of strength, increasing disability, and possible deformity.isted below are the nine different types of muscular dystrophy. Each type differs in the muscles affected, the age of onset, and its rate of progression. Some types are named for the affected muscles, including the following:

Muscular Dystrophy Specific muscle groups are affected by different types of muscular dystrophy. Often, there is a loss of muscle mass (wasting), which may be hard to see because some types of muscular dystrophy cause a buildup of fat and connective tissue that makes the muscle appear larger. This is called pseudohypertrophy.

- DMD is caused by a mutation in the dystrophin gene -- usually a large, out-of-frame deletion. Dystrophin is a structural protein associated with the support scaffolding of plasma membrane in muscle cells. Absent dystrophin causes a weakening of muscles, particularly skeletal and cardiac muscle.

Symptoms of Muscular Dystrophy Muscular Dystrophy: Symptoms. The symptoms of muscular dystrophy are the result of a deterioration of the body's muscles. This deterioration is due to the death of the muscle cells and muscle tissues and leads to ongoing muscle wasting and muscle weakness. Muscular dystrophy progresses and gets worse over time eventually.

Duchenne muscular dystrophy Duchenne muscular dystrophy (DMD) is a recessive X-linked form of muscular dystrophy, affecting around 1 in 3,600 boys, which results in muscle degeneration and premature death. The disorder is caused by a mutation in the gene dystrophin, located on the human X chromosome, which codes for the protein dystrophin.he main symptom of Duchenne muscular dystrophy, a progressive neuromuscular disorder, is muscle weakness associated with muscle wasting with the voluntary muscles being first affected, especially those of the hips, pelvic area, thighs, shoulders, and calves.

- Muscular dystrophy (MD) is a group of muscle diseases that results in increasing weakening and breakdown of skeletal muscles over time. The disorders differ in which muscles are primarily affected, the degree of weakness, how fast they worsen, and when symptoms begin.

- The main cause of the Duchenne and Becker types of muscular dystrophy is the muscle tissue's cytoskeletal impairment to properly create the functional protein dystrophin and dystrophin-associated protein complex.

Muscular Dystrophy Education & Treatment Each form of Muscular dystrophy has a different cause. They are all due to some form of inherited disorder. Frequently the defect in the muscle is one of a series of proteins which function on the surface of the muscle fiber, known as the dystrophin associated glycoprotein compex.

Duchenne Muscular Dystrophy Back to Top Causes. Duchenne muscular dystrophy is a form of muscular dystrophy that worsens quickly. Other muscular dystrophies (including Becker's muscular dystrophy) get worse much more slowly. Duchenne muscular dystrophy is caused by a defective gene for dystrophin (a protein in the muscles).However, it often occurs in people without a known family history of the condition. Because of the way the disease is inherited, boys are affected, not girls.uchenne muscular dystrophy is caused by a defective gene for dystrophin (a protein in the muscles).
