Emery-Dreifuss muscular dystrophy

Emery-Dreifuss muscular dystrophy (EDMD) is a genetic, degenerative disorder that mainly affects muscles responsible for movement, such as those in the upper arms, shoulders and calves. It also commonly involves the heart, which can lead to serious complications requiring ongoing medical care.

Symptoms usually begin in early childhood with joint contractures that restrict movement in areas like the neck, ankles and elbows. As the condition progresses, muscle weakness increases and cardiac problems often develop in adulthood, making regular monitoring essential.

First described in the 1960s by researchers Alan Emery and Fritz Dreifuss, EDMD can affect both boys and girls and is inherited through several genetic patterns, including X-linked recessive, autosomal dominant and autosomal recessive forms.
