Duchenne muscular dystrophy

(do͞o-shĕn′)
n.
A severe form of muscular dystrophy that begins in early childhood and almost exclusively affects males, characterized by progressive weakening of the muscles and usually leading to death from respiratory or cardiac failure. It is caused by lack of the protein dystrophin in muscle cells as a result of a recessive genetic mutation on the X chromosome.

Duchenne muscular dystrophy

An X-R disease caused by a deficiency of a muscle protein, dystrophin, which affects 1:3500 ♂, resulting in progressive muscular atrophy, wasting, and death by age 20, often related to respiratory–due to compromised diaphragm activity, or cardiac failure; calf and deltoid muscles display the typical finding of pseudohypertrophy.

Duchenne muscular dystrophy

A hereditary, X-linked RECESSIVE muscle disorder affecting males almost exclusively. It begins in the first three years of life and first affects the legs and buttocks. Usually, the muscles appear larger than normal (pseudo-hypertrophy) but are in fact very weak. The condition spreads to affect other muscles and death is usual between the age of 20 and 30. See also DYSTROPHIN. (Guillaume Benjamin Amand Duchenne, 1805–75, French neurologist).
