OBJECTIVE: To assess the applicability and the responsiveness of the motor function measure 1 (MFM) in a facio scapulo humeral dystrophy (FSHD) population. MATERIALS/PATIENTS AND METHODS: It is an observational, retrospective and multicenter, cohort study. MFM data came from the MFM database (see Only FSHD patients with at least one MFM-32 were included. The distributions of the MFM scores (total score and MFM D1, D2 and D3 subscores) were analyzed by age...

BACKGROUND: The main form of Facio-Scapulo-Humeral muscular Dystrophy is linked to copy number reduction of the 4q D4Z4 macrosatellite (FSHD1). In 5 % of cases, FSHD phenotype appears in the absence of D4Z4 reduction (FSHD2). In 70-80 % of these patients, variants of the SMCHD1 gene segregate with 4qA haplotypes and D4Z4 hypomethylation. CASE PRESENTATION: We report a family presenting with neuromuscular symptoms reminiscent of FSHD but without D4Z4 copy reduction...

Camptocormia is a disabling pathological, non-fixed, forward bending of the trunk. The clinical definition using only the bending angle is insufficient; it should include the subjectively perceived inability to stand upright, occurrence of back pain, typical individual complaints, and need for walking aids and compensatory signs (e.g. back-swept wing sign). Due to the heterogeneous etiologies of camptocormia a broad diagnostic approach is necessary. Camptocormia is most frequently encountered in movement disorders (PD and dystonia) and muscles diseases (myositis and myopathy, mainly facio-scapulo-humeral muscular dystrophy (FSHD))...

The aim of this study was to analyze motor unit reorganization in different types of progressive muscular dystrophies and congenital myopathies. The study population consisted of patients with genetically verified progressive muscular dystrophies: Duchenne (DMD) (n=54), Becker (BMD) (n=30), facio-scapulo-humeral (FSHD) (n=37), and Emery-Dreifuss (E-DD) (n=26). Patients with probable limb-girdle dystrophy (L-GD) (n=58) and congenital myopathies (n=35) were also included in the study. Quantitative EMG recordings were obtained from 469 muscles...

OBJECTIVE: Facioscapulohumeral muscular dystrophy (FSHD) is linked to either contraction of D4Z4 repeats on chromosome 4 or to mutations in the SMCHD1 gene, both of which result in the aberrant expression of the transcription factor DUX4. However, it is still difficult to correlate these genotypes with the phenotypes observed in patients. Because we have recently shown that mice with disrupted Fat1 functions exhibit FSHD-like phenotypes, we have investigated the expression of the human FAT1 gene in FSHD...

OBJECTIVE: The objective of this study was to evaluate the clinical usefulness of whole-body magnetic resonance imaging (MRI) in facio-scapulo-humeral muscular dystrophy (FSHD). METHODS: In 20 patients with genetically proven FSHD1, we prospectively assessed muscular involvement and correlated the results of semi-quantitative manual muscle testing and other parameters such as disease duration, creatine kinase (CK) levels and repeat length of the D4Z4 locus with whole-body MRI...

Pre-excitation-syndrome has not been reported as a phenotypic feature of facio-scapulo-humeral muscular dystrophy (FSH-MD). In a 39-year-old male with FSH-MD due to a reduced tandem repeat size in the D4Z4-locus on chromosome 4q35, cardiac involvement, manifesting as an incomplete right bundle-branch-block, tall T-waves in V 3-5, ST-elevation in V 2-4, and mild thickening of the left ventricular myocardium, was first recognised 10 years earlier. Follow-up at age 39 years revealed mild myocardial thickening, two intra-ventricular aberrant bands, and, surprisingly, intermittent pre-excitation on a routine electrocardiography...

The Mediterranean countries are distinguished with their peculiar genetic pool and diversities. Recessive diseases often present with their own founder mutations. In some instances this is shared with neighboring populations. Dominant disorders in the area are increasingly recognized as health care providing systems and technology improve. Among muscular dystrophies Duchenne and Becker types constitute the major fraction in almost all societies. This is followed by various forms of limb-girdle muscular dystrophy...

Facio-scapulo-humeral dystrophy (FSHD) results from deletions in the subtelomeric macrosatellite D4Z4 array on the 4q35 region. Upregulation of the DUX4 retrogene from the last D4Z4 repeated unit is thought to underlie FSHD pathophysiology. However, no one knows what triggers muscle defect and when alteration arises. To gain further insights into the molecular mechanisms of the disease, we evaluated at the molecular level, the perturbation linked to the FSHD genotype with no a priori on disease onset, severity or penetrance and prior to any infiltration by fibrotic or adipose tissue in biopsies from fetuses carrying a short pathogenic D4Z4 array (n = 6) compared with fetuses with a non-pathogenic D4Z4 array (n = 21)...

The Fragile X-Related 1 gene (FXR1) is a paralog of the Fragile X Mental Retardation 1 gene (FMR1), whose absence causes the Fragile X syndrome, the most common form of inherited intellectual disability. FXR1P plays an important role in normal muscle development, and its absence causes muscular abnormalities in mice, frog, and zebrafish. Seven alternatively spliced FXR1 transcripts have been identified and two of them are skeletal muscle-specific. A reduction of these isoforms is found in myoblasts from Facio-Scapulo Humeral Dystrophy (FSHD) patients...

Here we describe the first case of myotonic dystrophy type 1 (DM1) associated with facio-scapulo-humeral dystrophy (FSHD). From a clinical point of view, the patient displayed a pattern of muscle involvement reminiscent of both disorders, including hand-grip myotonia, facial, axial and distal limbs muscle weakness as well as a bilateral winged scapula associated with atrophy of the pectoralis major muscle and lumbar lordosis; pelvic muscles were mostly spared. An extensive muscle MRI assessment including neck, shoulder, abdominal, pelvic and lower limb muscles documented radiological features typical of DM1 and FSDH...

We studied respiratory function and Chest Wall kinematics in a large population of adult patients affected by slow course muscular dystrophies such as Limb-Girdle Muscular Dystrophy (LGMD, n=38), Becker Muscular Dystrophy (BMD, n=20) and Facio-Scapulo Humeral Dystrophy (FSHD, n=30), through standard spirometry and through the Optoelectronic Plethysmography, to measure the thoraco-abdominal motion during Quiet Breathing and Slow Vital Capacity maneuvers. Within the restrictive pulmonary syndrome characterizing LGMD and FSHD, several different thoraco-abdominal patterns compared to those of healthy subjects were present in the more advanced stages of the disease...

Using cellular models that mimic the organizations of the subtelomeric 4q35 locus found in patients affected with Facio-Scapulo-Humeral Dystrophy (FSHD) and in healthy individuals, we recently investigated the biological function of the D4Z4 macrosatellite in this subtelomeric context.We demonstrated that D4Z4 acts as a CTCF and A-type lamins dependent insulator element exhibiting both enhancer- blocking and barrier activities, and displaces a telomere towards the nuclear periphery. This peripheral positioning activity lies within a short sequence that interacts with CTCF and A-type lamins...

Both genetic and epigenetic alterations contribute to Facio-Scapulo-Humeral Dystrophy (FSHD), which is linked to the shortening of the array of D4Z4 repeats at the 4q35 locus. The consequence of this rearrangement remains enigmatic, but deletion of this 3.3-kb macrosatellite element might affect the expression of the FSHD-associated gene(s) through position effect mechanisms. We investigated this hypothesis by creating a large collection of constructs carrying 1 to >11 D4Z4 repeats integrated into the human genome, either at random sites or proximal to a telomere, mimicking thereby the organization of the 4q35 locus...

Strategy for the diagnosis of a muscle weakness includes two steps: to rely the weakness to a muscular origin and to find the aetiology. A muscular deficit is purely motor, without sensory signs, involving mainly axial and proximal muscles. The essential informations for aetiological characterization are: 1st) a family history, indicating a genetic origin, 2nd the chronological profile, 3rd) the clinical pattern (deficit topography, modification of muscle volume, fatigability, contractures, myotonia, oculobulbar, respiratory or cardiac involvement), 4th) investigations (CK level, EMG, muscle imaging muscle, biopsy, genetic testing)...

The number of D4Z4 repeats in the subtelomeric region of chromosome 4q is strongly reduced in patients with Facio-Scapulo-Humeral Dystrophy (FSHD). We performed chromosome conformation capture (3C) analysis to document the interactions taking place among different 4q35 markers. We found that the reduced number of D4Z4 repeats in FSHD myoblasts was associated with a global alteration of the three-dimensional structure of the 4q35 region. Indeed, differently from normal myoblasts, the 4qA/B marker interacted directly with the promoters of the FRG1 and ANT1 genes in FSHD cells...

With improved screening of patients with primary and secondary myopathies and more comprehensive investigations it turns out that an increasing number of patients with myopathies develops cardiac disease (cardiac involvement), before or after onset of the neuromuscular abnormalities. Cardiac involvement in myopathies manifests within the myocardium or the cardiac conduction system with impulse generation or conduction disturbances. An increasingly recognized rhythm abnormality in these patients is atrial fibrillation/flutter (AFI/AFL), which carries an increased risk for stroke embolism and represents an absolute indication for oral anticoagulation (OAC)...
