Duchenne muscular dystrophy is a rare genetic disorder that primarily affects males. Due to the severity of the condition, there are no famous individuals known to have had Duchenne muscular dystrophy.
Muscular dystrophy is a group of genetic disorders characterized by muscle weakening and wasting, while Duchenne muscular dystrophy (DMD) is a specific type of muscular dystrophy caused by mutations in the dystrophin gene. DMD is the most common and severe form of muscular dystrophy, typically affecting boys and leading to progressive muscle weakness and loss of function.
It is estimated that approximately 1 in every 3,500 to 5,000 boys are born with Duchenne muscular dystrophy worldwide. The exact number of individuals with this disease can vary by region and population.
People with Duchenne muscular dystrophy (DMD) do not produce dystrophin because they have a genetic mutation that affects the production of this protein. Dystrophin is essential for maintaining the structure and function of muscle cells, and its absence in individuals with DMD leads to muscle weakness and degeneration.
It effects only males. Women are carriers
In most cases this is diagnosed by age five. In that case the child would need a wheelchair by about age 12. Most likely the child will start to have heart and lung issues by late teens or early twenties. My guess no longer than thirty.
Genetic counseling is advised when there is a family history of muscular dystrophy. Women may have no symptoms but still carry the gene for the disorder. Duchenne muscular dystrophy can be detected with about 95% accuracy by genetic studies performed during pregnancy. http://www.nlm.nih.gov/medlineplus/ency/article/001190.htm http://en.wikipedia.org/wiki/Muscular_dystrophy

Not necessarily. Inheritiance of muscular dystrophy is not automatic. Children of a parent with muscular dystrophy have a 50% chance of inheriting the condition, depending on the specific type and genetic pattern of the disease.
Mixed Muscular Dystrophy is a rapid progression form of Muscular Dystrophy. This normally occurs to people between the ages of 30 and 50 and death normally occurs within 5 years.
Prevalence of MD is higher in males. In the United States, Duchenne and Becker MD occur in approximately one in 3,300 boys. Overall incidence of MD is about 63 per one million people.
1 in 3500 males
