Duchene Muscular Dystrophy

Duchene Muscular Dystrophy

The reason why i have chosen this title. Is because my cousin he has muscular dystrophy and they said he would only live till he was 18 and he is 21 now.

Definition of the disorder

If you have muscular dystrophy it will disable your body from walking or any major movements, like moving your whole arm, or walking or turning your head to the side. What you mainly can do is talk and use your hands.

Description of the symptoms

Many kids with muscular dystrophy follow a normal pattern of development during their first few years of life. But in time they develop problems with movement. A child who has MD may start to stumble, waddle, have difficulty going up stairs, and toe walk (walk on the toes without the heels hitting the floor or even crawl on their hands and knees until they can't anymore). A child may start to struggle to get up from a sitting position or have a hard time pushing things, like a wagon or a tricycle.

The cause of Duchene

Dystrophin is also believed to carry signals between the inside and outside of muscle fibers. Without dystrophin, muscles are unable to operate properly, and eventually suffer progressive damage.

The dystrophin gene is carried on the X-chromosome. Boys only have one X-chromosome, making them more susceptible to dystrophin damage, as they lack a second X-chromosome to make up for the damaged gene.


Duchene Muscular dystrophy is passed through the genes.

How The disorder is inherited

DMD is inherited in a pattern called X-linked inheritance. The DMD gene is carried by women, but does not usually cause problems in girls or women. This is because of there being two X chromosomes in women; one X chromosome has the faulty DMD gene, and the other X chromosome has a normal gene, which compensates for the faulty one.

How is the disorder treated?

There is no treatment for this disease, and at the moment there is no cure found for muscular dystrophy.

How many and what type of people are most likely to have the disorders?

Muscular Dystrophy is mainly affecting boys. And the women are the carriers, there is a 50% chance of the woman having it and a 50% chance of the child having it.

Application of research

I have learned how it was inherited and passed on.
