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...

متن کاملTreatment of facioscapulohumeral muscular dystrophy with Denosumab
BACKGROUND Facioscapulohumeral muscular dystrophy (FSHD) is the 3(rd) most common form of muscular dystrophy. Effective treatments for any of the muscular dystrophies have yet to be realized. This report describes such a treatment. CASE REPORT A 66 year old female was diagnosed with osteoporosis. She had been diagnosed with FSHD muscular dystrophy a number of years previously by both genetic ...
متن کاملAtypical phenotypes in patients with facioscapulohumeral muscular dystrophy 4q35 deletion.
BACKGROUND Facioscapulohumeral muscular dystrophy (FSHD) is associated with a deletion on chromosome 4q35. Recent studies have shown that this deletion is found in patients with other phenotypes in addition to those with the classic Landouzy-Dejerine FSHD phenotype. OBJECTIVE To examine patients with atypical phenotypes and an FSHD deletion on chromosome 4q35. DESIGN Clinical characterizati...
