Emery-Dreifuss muscular dystrophy (EDMD) is characterized by the clinical triad of joint contractures that begin in early childhood, slowly progressive muscle weakness and wasting initially in a humeroperoneal distribution that later extends to the scapular and pelvic girdle muscles, and cardiac involvement that usually occurs after the second decade of life. So far, five genes, EMD (emerin), LMNA, SYNE (nesprin)1, SYNE2 and FHL1, have been associated to EDMD phenotypes, that can be inherited following an X-linked, autosomal dominant or autosomal recessive pattern of inheritance. Most of genes known to be associated with EDMD are critical for nuclear envelope integrity.
