Facioscapulohumeral muscular dystrophy
Facioscapulohumeral muscular dystrophy (FSHD) is a progressive myopathy with a relatively late age of onset (usually in the late teens) compared with Duchenne and many other muscular dystrophies. The current FSHD disease model postulates that contraction of the D4Z4 array at chromosome 4q35 leads to a more open chromatin conformation in that region and allows transcription of the DUX4 gene. DUX...

facioscapulohumeral muscular dystrophy (fshd)is characterized by weakness of the facial, scapular muscles and the dorsiflexors of the foot. severity in this disorder is highly variable. approximately 95% of individuals with fshd phenotype have type 1 fshd, with d4z4 allele of between one and ten repeat units and about 5% have type 2 fshd with mutations in the chromatin modifier smchd1gene whic...
متن کاملEarly onset facioscapulohumeral muscular dystrophy.
We report 10 patients (5 familial, 5 sporadic) with facioscapulohumeral muscular dystrophy (FSHD) with onset of facial and shoulder girdle weakness in early infancy. They showed the same broad range of clinical signs and symptoms as can be seen normally in FSHD. In 7 patients Southern blotting with p13E-11 was performed which showed an abnormal EcoRI fragment (13-22 kb) in 6 of them. We conclud...

Submit Manuscript | http://medcraveonline.com Facioscapulohumeral muscular dystrophy (FSHD) is the third most common myopathy found in adults, with an overall incidence of more than 1:20000 (source: Orphanet). It is classified among progressive muscular dystrophies, characterized by muscular fiber necrosis and degeneration giving rise to progressive muscular weakness and atrophy. Weakness usual...
متن کاملFacioscapulohumeral muscular dystrophy in the Dutch population.
Extrapolating the figures from a previous study on FSHD in a province of The Netherlands to the entire Dutch population suggests that at present a nearly complete overview is obtained of all symptomatic kindred. In 139 families, dominant inheritance was observed in 97, a pattern compatible with germline mosaicism in 6, while sporadic cases were found in 36 families. A mutation frequency of 9.6%...
