The Haldane rule (Haldane, 1935) predicts that one-third of cases of a genetic lethal X-linked recessive will be the consequence of new mutation.Haldane (1956) further suggested that the mutation rate for Duchenne muscular dystrophy might be higher in males. Duchenne muscular dystrophy (DMD) is a lethal X-linked recessive pathology in which lack of functional dystrophin leads to progressive muscle degeneration culminating in loss of locomotion and premature death. Duchenne muscular dystrophy (DMD) represents one of the most devastating types of muscular dystrophies which affect boys already at early childhood.
