What causes duchenne muscular dystrophy?

Dr. Beth Howell

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.

Genetic disorder: Duchenne's muscular dystrophy is an x linked genetic disorder causing abnormalities of the muscle fiber and eventual degeneration.

See link below: "duchenne results in progressive loss of strength and is caused by a mutation in the gene that encodes for dystrophin. Because dystrophin is absent, the muscle cells are easily damaged. The progressive muscle weakness leads to serious medical problems, particularly issues relating to the heart and lungs." - see more at: http://www.Parentprojectmd.Org/site/pageserver?Pagename=understand_about#sthas.

About 1/3 of the cases are caused by new mutations, the others are familial. Diagnosis is usually evident from clinical features. The abnormality is in the cytoskeletal protein dystrophin.
