D ICD – These findings represented the first identification of mutations in a component of the nuclear lamina as a cause of an inherited muscle disorder.

The patient’s father and 4 cousins all had cardiac disease without muscle weakness ranging from nonspecific ‘heart attacks’ to dilated cardiomyopathy and arrhythmia. J Med Genet accepted.

Orphanet: Distrofia muscular de Emery Dreifuss, autossómica dominante EDMD2

The results were consistent with germline mosaicism or a recurrent de novo event. Emery-Dreifuss muscular dystrophy-2 shows autosomal dominant inheritance Bonne et al. In addition, 12 patients had normal electrocardiographic findings, most of whom also had normal echocardiographic findings; these patients ranged in age from 4 to 25 years. Autopsy findings in literature also show this 1. Continuing navigation will be considered as acceptance of this use.


Cases reported have been described under a variety of names, including scapuloperoneal syndrome, X-linked muscular dystrophy with contractures, rigid spine syndrome, Distrocia Lejonne syndrome and humeroperoneal neuromuscular disease 1.

This page was last edited on 7 Novemberat Disease musculwr ranged from 17 to 42 years, and cardiomyopathy appeared late dreifusz the disease, always after skeletal muscle involvement.

Becker suggested that the Hauptmann-Thannhauser eponym be attached to autosomal dominant muscular dystrophy with early contractures and cardiomyopathy because Hauptmann and Thannhauser2 German immigrants working in Boston, reported the disorder in a family of French Canadian descent in which 9 persons in 3 generations were affected by a form of muscular dystrophy ‘not heretofore described in the literature.

Emery–Dreifuss muscular dystrophy

The disorder was intermediate between typical limb-girdle muscular dystrophy e. The proximal upper and distal lower limb muscles are most commonly affected in the initial stages, while the pectoral and pelvic girdles are generally affected later.

Device entrapped in subvalvular apparatus: The birth and early development of our patient were normal. Summary This disease is described under Emery-Dreifuss muscular ejery.

ECG is recommended in all patients, 6 and echocardiography should be performed to exclude structural heart disease. She sat unsupported at age 2 years and walked independently from age 4 years with frequent falls and a waddling gait.


Syncopal episodes, as in the case of our patient, had their onset at age 24, with no other symptoms reported until then. Emery-Dreifuss muscular dystrophy with autosomal dominant transmission.

Init was published the first report of two related females in whom the inheritance seemed to be autosomal dominant 2. Check this box if you wish to receive a copy of your message. No type grouping or angular fibers were seen.

Genetic localization of a newly recognized autosomal dominant limb-girdle muscular dystrophy with cardiac involvement LGMD1B to chromosome 1q Muscular biopsy of a deltoid muscle showed increased variability in muscle fiber size due to moderate numbers dmery atrophic and hypertrophic muscle fibers. Some other sporadic cases, including in women, have been reported 2,3,8. There were no significant morphological findings in the other organs. Further cardiac study, including Ddreifuss ECG monitoring, showed sinus rhythm, with minimum, mean and maximum heart rates of 32, 54 and 90 bpm, respectively, and periods of first-degree AVB.

The only relevant family history was the premature death of a maternal aunt, distrofja due to neuromuscular disease. This affection of the anterior horn cells and of the motor nuclei of some cranial nerves, may present with cardiac abnormalities, in some cases, but not with atriventricular block 9.
