Hereditary: It is inherited because of a defective gene on the x chromosome (female sex chromosome). It is referred to as a "sex-linked recessive" inheritance pattern. Girls get two x chromosomes, and the healthy one overrules the unhealthy gene, preventing girls from contracting the disorder. Boys get an x and a y. If the x has the defective gene, there is no corresponding gene on the y to overrule it.
Dr. Michael Amster
Specializes in Pediatrics
Genetic disorder: Duchenne's muscular dystrophy is an x linked genetic disorder causing abnormalities of the muscle fiber and eventual degeneration.

Steroids: Currently the mainstay of therapy for duchenne is still steroids. Steroids slow the progression of the disease but are not a cure. There are many promising therapies being tested, but so far no others available at this time. For more information visit mda.Org or duchenneconnect.

Weakness: Duchenne's muscular dystrophy (dmd) is caused by a faulty protein. It results in weakness that starts in the hip girdle and progresses to other areas of the body. It can result in scoliosis and tight muscles. Later in the course it can result in loss of function and frequent respiratory infections. The disease is currently incurable, but steroids can often delay the progression of symptoms.
