What is Duchenne muscular dystrophy PDF?

Duchenne muscular dystrophy is a muscle disease caused by mutation in the gene that encodes the cytoskeletal protein dystrophin. It is inherited in an X-linked recessive fashion. A number of therapies are continuously being developed to slow down the progression of the disease and increase patients’ life expectancy.

How many cases of muscular dystrophy per year?

The study estimated the diagnosed incidence of DMD in the US at 17.24 per 100,000 live male births in 2019. This corresponds to about 362 cases in that year. The diagnosed prevalence of the disease was 6.09 per 100,000 males across all age groups. This corresponds to about 10,015 cases.

What is the full form of DMD?

Duchenne muscular dystrophy is a form of muscular dystrophy. It worsens quickly. Other muscular dystrophies (including Becker muscular dystrophy) get worse much more slowly. Duchenne muscular dystrophy is caused by a defective gene for dystrophin (a protein in the muscles).

Who was the first person to have muscular dystrophy?

The first historical account of MD was reported by Conte and Gioja in 1836. They described two brothers with progressive weakness starting at age 10 years. These boys later developed generalized weakness and hypertrophy of multiple muscle groups, which are now known to be characteristic of the milder Becker MD.

What actor has muscular dystrophy?

Actor and Comedian With Muscular Dystrophy Works to Open Doors for More Disabled Stories. Steve Way advocates for universal healthcare, disability rights, and more film roles for disabled actors. Steve Way wants you to know that, really, he’s “a regular guy.”

Who has muscular dystrophy?

Muscular dystrophy occurs in both sexes and in all ages and races. However, the most common variety, Duchenne, usually occurs in young boys. People with a family history of muscular dystrophy are at higher risk of developing the disease or passing it on to their children.

What proteins are associated with DMD?

Both disorders are caused by mutations in the DMD gene that encodes a 427-kDa cytoskeletal protein called dystrophin. The vast majority of DMD mutations result in the complete absence of dystrophin, whereas the presence of low levels of a truncated protein is seen in BMD patients.

What are some facts about muscular dystrophy?

Overview. Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass.

  • Symptoms. The main sign of muscular dystrophy is progressive muscle weakness.
  • Causes. Certain genes are involved in making proteins that protect muscle fibers.
  • Risk factors.
  • Complications.
  • What are the first signs of muscular dystrophy?

    Weakness starts in the arms and later affects the legs Sometimes weakness occurs in the face

  • Heart problems
  • Limited movement at certain joints caused by tightening of the tissues around the joint (contracture)
  • What is the life span of muscular dystrophy?

    The average life expectancy of people with muscular dystrophy depends on the form of the disease. Most patients with one of the nine forms of muscular dystrophy live into adulthood, reports WebMD. However, people with Duchenne muscular dystrophy live only into their 30s, although a few live until age 50. People with Duchenne muscular dystrophy are usually born with the disease.
