Emery–Dreifuss muscular dystrophy
Diagram of the muscles preferentially weakened and the locations of contraction development in EDMD2, due to LMNA mutation.
SpecialtyNeurology, neuromuscular medicine

ComplicationsHeart failure
Usual onsetFirst or second decade
DurationLifelong
CausesMutation in one of several gene, including EMD LMNA genes[2]
Diagnostic methodGenetic testing. Adjunctive: creatine kinase, EMG, and muscle MRI[3]
TreatmentPhysical therapy, orthopedic surgery, pacemaker[1]
Frequency0.39 per 100,000[3]

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.[3][4] It is named after Alan Eglin H. Emery and Fritz E. Dreifuss.[5][6]
