Duchenne Muscular Dystrophy and Its Impact on Communication

"Communication is the communication or exchange of ideas, sentences, or information by words, sentences, or symbols" (Dictionary.com, 2014). It is expressive and comprehensive. Because we are social creatures, that is an extremely important part of our lives, especially for humans. Our muscles account for 40% of our bodies and help us accomplish a lot of work. Muscles will help us, from yawning to rising, dancing, breathing, and communication. Imagine that your muscles are getting less and less and ultimately they do not work at all.

Disease muscular dystrophy is a disease characterized by weakness and deterioration of skeletal muscle. There are more than 30 different forms of muscular dystrophy, but the two most common are Duchenne and Becker muscular dystrophy (Baronceri). These two forms of disease are sexually related, and mainly affect men. Men usually do not accept other X chromosomes to inherit the defective X chromosome from the mother and neutralize the defective X chromosome (male is XY). Affected people have difficulty in performance

Duchenne Muscular Dystrophy (DMD): DMD is the most common form of muscular dystrophy. This is because the dystrophin gene mutation is on the X chromosome, mainly because it affects boys. This is the most common form of muscular dystrophy and is one of the most common genetic diseases of humans, and it occurs in boys of approximately 1: 5000. The boy lost his ability to walk between teens and died in the early days of adulthood. Dystrophin is the largest gene in the human genome (the 11 kb coding region) and is therefore too large to be packaged in an AAV vector. Micro-muscular dystrophy proteins, including the most important regions of the gene but excluding redundant aspects, have been developed for AAV gene therapy. Approximately 40% of the micro-muscular dystrophy protein representing the coding sequence of the human dystrophin gene was delivered to the biceps brachii of six boys by intramuscular injection using rAAV 2.5. Micro-muscular dystrophy was detected in 2 out of 4 cases at 42 days but not in 2 cases 90 days after injection
