X-linked Emery-Dreifuss muscular dystrophy(EDMD1)

MedGen UID:
1720295
Concept ID:
C5243475
Disease or Syndrome
Synonyms: EDMD1; EMD-Related Emery-Dreifuss Muscular Dystrophy, X-Linked; Emery-Dreifuss muscular dystrophy 1, X-linked; Muscular dystrophy, tardive Emery-Dreifuss type, with contractures
Modes of inheritance:
X-linked recessive inheritance
MedGen UID:
375779
Concept ID:
C1845977
Finding
Source: Orphanet
A mode of inheritance that is observed for recessive traits related to a gene encoded on the X chromosome. In the context of medical genetics, X-linked recessive disorders manifest in males (who have one copy of the X chromosome and are thus hemizygotes), but generally not in female heterozygotes who have one mutant and one normal allele.
 
Gene (location): EMD (Xq28)

Disease characteristics

Excerpted from the GeneReview: Emery-Dreifuss Muscular Dystrophy
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 humero-peroneal distribution that later extends to the scapular and pelvic girdle muscles; and cardiac involvement that may manifest as palpitations, presyncope and syncope, poor exercise tolerance, and congestive heart failure along with variable cardiac rhythm disturbances. Age of onset, severity, and progression of muscle and cardiac involvement demonstrate both inter- and intrafamilial variability. Clinical variability ranges from early onset with severe presentation in childhood to late onset with slow progression in adulthood. In general, joint contractures appear during the first two decades, followed by muscle weakness and wasting. Cardiac involvement usually occurs after the second decade and respiratory function may be impaired in some individuals. [from GeneReviews]

Additional description

From OMIM
Emery-Dreifuss muscular dystrophy (EDMD1) is a degenerative myopathy characterized by weakness and atrophy of muscle without involvement of the nervous system. Flexion deformities of the elbows dating from early childhood, mild pectus excavatum, signs of cardiac involvement and absence of muscle pseudohypertrophy, involvement of the forearm muscles, and mental retardation distinguish the Emery-Dreifuss form (EDMD1) from the Becker form (300376). Genetic Heterogeneity of Emery-Dreifuss Muscular Dystrophy Autosomal dominant Emery-Dreifuss muscular dystrophy-2 (EDMD2; 181350) is caused by mutation in the lamin A/C gene (LMNA; 150330); autosomal recessive EDMD3 (616516) is also caused by mutation in the LMNA gene. Additional autosomal dominant forms include EDMD4 (612998), caused by mutation in the SYNE1 gene (608441); EDMD5 (612999), caused by mutation in the SYNE2 gene (608442); and EDMD7 (614302), caused by mutation in the TMEM43 gene (612048). A second X-linked form (EDMD6; see 300696) is caused by mutation in the FHL1 gene (300163).  http://www.omim.org/entry/310300

Clinical features

From HPO
Sudden cardiac death
MedGen UID:
38841
Concept ID:
C0085298
Pathologic Function
The heart suddenly and unexpectedly stops beating resulting in death within a short time period (generally within 1 h of symptom onset).
Knee flexion contracture
MedGen UID:
98042
Concept ID:
C0409355
Finding
A bent (flexed) knee joint that cannot be straightened actively or passively.
Atrioventricular block
MedGen UID:
13956
Concept ID:
C0004245
Disease or Syndrome
Delayed or lack of conduction of atrial depolarizations through the atrioventricular node to the ventricles.
Palpitations
MedGen UID:
14579
Concept ID:
C0030252
Finding
A sensation that the heart is pounding or racing, which is a non-specific sign but may be a manifestation of arrhythmia.
Atrial arrhythmia
MedGen UID:
39317
Concept ID:
C0085611
Pathologic Function
A type of supraventricular tachycardia in which the atria are the principal site of electrophysiologic disturbance.
First degree atrioventricular block
MedGen UID:
43215
Concept ID:
C0085614
Disease or Syndrome
Delay of conduction through the atrioventricular node, which is manifested as prolongation of the PR interval in the electrocardiogram (EKG). All atrial impulses reach the ventricles.
Absent P wave
MedGen UID:
324892
Concept ID:
C1837847
Finding
The P wave that normally precedes each QRS complex by a fixed PR interval of 120 to 200 milliseconds is not present.
Waddling gait
MedGen UID:
66667
Concept ID:
C0231712
Finding
Weakness of the hip girdle and upper thigh muscles, for instance in myopathies, leads to an instability of the pelvis on standing and walking. If the muscles extending the hip joint are affected, the posture in that joint becomes flexed and lumbar lordosis increases. The patients usually have difficulties standing up from a sitting position. Due to weakness in the gluteus medius muscle, the hip on the side of the swinging leg drops with each step (referred to as Trendelenburg sign). The gait appears waddling. The patients frequently attempt to counteract the dropping of the hip on the swinging side by bending the trunk towards the side which is in the stance phase (in the German language literature this is referred to as Duchenne sign). Similar gait patterns can be caused by orthopedic conditions when the origin and the insertion site of the gluteus medius muscle are closer to each other than normal, for instance due to a posttraumatic elevation of the trochanter or pseudarthrosis of the femoral neck.
Loss of ambulation
MedGen UID:
332305

Inability to walk in a person who previous had the ability to walk.

98052

C0410264

A contracture of the Achilles tendon.
