X-Linked Reces. MD: Duchenne dystrophy is inherited as an x-linked recessive trait, carried in women. It affects about 1in 3500 male births with no geographic/ethnic variation. 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. It is unclear why the lack of dystrophin ->findings.

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.

Dr. Beth Howell
Psychiatry 42 years experience
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.
