How does one acquire duchenne muscular dystrophy?

Bad genes: Duchenne type of muscular dystrophy is located on the x chromosome and is found in males. There are specific genetic tests that describe the disorder in detail. Women are carriers, and boys develop symptoms during early childhood. In utero testing is available. There is no cure, but early detection and possible use of steroids with appropriate therapy may modify the course.

X chromosome : The disease is carried on the x chromosome. As such typically only males (with one x chromosome) will exhibit symptoms. Females will carry the disease but since one of their x chromosomes is typically normal, they won't exhibit signs.
