Duchenne Muscular Dystrophy

CauseThe X chromosome codes for a protein called dystrophin, among other things. People with DMD have inherited a defective version of the gene that's responsible for dystrophin, which causes their muscle cells to be especially weak and prone to damage.

EffectDMD causes rapid destruction of the muscles, starting in the pelvis and legs. A person with DMD will lose the ability to walk before puberty. DMD also causes heart and lung complications that can be life threatening. Additionally, learning disorders and lowered IQs are common with DMD.

Duchenne Muscular Dystrophy (DMD) is an X-linked disorder that causes muscle weakness and deterioration which gets progressively worse over time.

Treatment and Management

Duchenne Muscular Dystrophy

There is no known cure for DMD. However, it can be managed using leg, foot, and ankle braces, through walking exercise, physical therapy, and the use of wheelchairs for locomotion. People with DMD must have thorough medical exams often to prevent cardiac, pulmonary, and flexibility problems. There's also many support groups available for people with any kind of muscular dystrophy.

Symptoms of DMD are usually appear before six years of age.

The current life expectancy of a person with DMD is around 30 years.

TestingGenetic testing, electromyography, and muscle biopsies can be used in diagnosing DMD. Punnett squares and pedigrees can be used to predict DMD, but there are some cases that happen spontaneously with no family history.
