Emery Dreifuss Muscular Dystrophy

Emery–Dreifuss muscular dystrophy (EDMD) is a type of muscular dystrophy, a group of heritable diseases that cause progressive impairment of muscles. EDMD affects muscles used for movement (skeletal muscles), causing atrophy, weakness and contractures. It almost always affects the heart, causing abnormal rhythms, heart failure, or sudden cardiac death.
It is rare, affecting 0.39 per 100,000 (1 per 250,000) people. It is named after Alan Eglin H. Emery and Fritz E. Dreifuss.
