Answer

Although it was probably first described in the early 1900s, Emery-Dreifuss muscular dystrophy (EDMD) was not clearly delineated as a separate disease until the 1960s. In 1961, Dreifuss and Hogan described a large family with an X-linked form of muscular dystrophy that they considered to be a benign form of Duchenne muscular dystrophy. Subsequent evaluation of this family by Emery and Dreifuss in 1966 led to distinguishing this type of X-linked dystrophy from the more severe Duchenne and Becker muscular dystrophies. An autosomal dominant form of EDMD was described by several authors in the early 1980s. The genetic defects in both the X-linked recessive form and the autosomal dominant form of EDMD have been determined.
