Key Signs Of Duchenne Muscular Dystrophy

Duchenne muscular dystrophy (DMD) is a hereditary disorder that involves progressive muscle weakness and degeneration. There are nine overarching types of muscular dystrophy. In the case of Duchenne muscular dystrophy, a patient doesn't create dystrophin, which is one of the proteins responsible for keeping the muscle cells intact. The symptoms usually start between the ages of three and five. Though the disease usually affects boys, there have been rare cases where girls develop some symptoms. It should be noted the mother is the one who passes on the gene for Duchenne muscular dystrophy.
