Beck·er muscular dystrophy

 (bĕk′ər)
n.
A form of muscular dystrophy that begins in late childhood or adolescence, almost exclusively affects males, and is characterized by progressive weakening of the muscles that is similar to but less severe than in Duchenne muscular dystrophy. It is caused by a recessive genetic mutation on the X chromosome that results in insufficiency or abnormality of the protein dystrophin in muscle cells.

[After Peter Emil Becker (1908-2000), German human geneticist .]
