In brief: Coding

Like the order of letters in a word can spell and mean something different, so too can the order and type of genes cause a particular disease presentation.
When someone has genes for muscular dystrophy, it depends on how strong those genes are and what they code for that determines what form of dystrophy they will have.

Duchenne muscular dystrophy is caused by the failure of the body to make dystrophin. Beckers dystrophy has more dystrophin, but not nearly as much as normal. There are other genetic defects that i don't have enough room to go into further detail. Try www.Aaos.Org or another reputable site.
