Duchenne Muscular Dystrophy (DMD) is a genetic mutation that's recessive and X- linked. It is on the 'p' arm of the X chromosome (to be more particular, the Xp21 chromosome). DMD is also deadly significance that the person impacted by DMD will die because of it. Since DMD is situated on the X chromosome, it mostly affects men. It's immensely unusual for a female to inherit the gene because her father would need to own DMD and her mum would need to carry the gene. Theoretically, if a mother takes the gene as well as the father has DMD, there's a 25 percent chance that if they have a kid, she will have DMD. But because DMD affects a rather small number of men, this result is very uncommon. Regular muscles have a protein called dystrophin, which without it, the muscle cannot function properly. DMD is a disorder which has a shortage of dystrophin from the muscles. The lack of this protein causes these side effects: delayed learning in speech, difficulty in ordinary activities such as running or walking, along with fatigue. Many boys, from age six, will start to have abnormally huge muscles, intellectual handicap (which, if occurs, does not worsen), and learning issues. Also, cardiovascular disease and respiratory difficulties usually start by age 20. DMD causes soreness and pain that worsens very quickly, whereas Becker's Muscular Dystrophy (another kind of muscular dystrophy) worsens much slower. Most boys will probably be incapable of waking by the age of 12 and will need to use a wheelchair. DMD affects 1 out of every 3,600 boy babies. Since this disease is genetic, the chance of DMD running in the household is extremely high (MedlinePlus 2013). With neurological, heart, and muscle building assessments, many signs of DMD can show. A few of the things th...
