UK Facioscapulohumeral Muscular Dystrophy (FSHD) Patient Registry
The United Kingdom (UK) Facioscapulohumeral Dystrophy (FSHD) Patient Registry launched in May 2013. Funded by the Muscular Dystrophy Campaign and supported by the TREAT-NMD Alliance. This patient driven registry collects the internationally agreed core dataset, an outcome of an ENMC Workshop held in 2010 [1], through a novel online portal (http://www.fshd-registry. org/uk). Genetic details are ...
متن کاملdetermination of contraction of d4z4 repeats on chromosome 4q35 in iranian facioscapulohumeral muscular dystrophy patients
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 کاملAsymptomatic carriers and gender differences in facioscapulohumeral muscular dystrophy (FSHD).
Facioscapulohumeral muscular dystrophy is an autosomal dominant muscle disorder, mapped to 4q35. It is characterized by remarkable inter- and intrafamilial clinical variability ranging from severe phenotype to asymptomatic carriers. The aim of the present study was to assess the size of the Eco RI fragment in a large sample of asymptomatic or minimally affected carriers as well as symptomatic p...
متن کاملImproved molecular diagnosis of facioscapulohumeral muscular dystrophy (FSHD): validation of the differential double digestion for FSHD.
A major advance in the molecular diagnosis of facioscapulohumeral muscular dystrophy is the recently reported elimination of confounding DNA fragments arising from homologous sequences located at 10q26. In order to evaluate the specificity and sensitivity of this important diagnostic test, we have compared a group of 130 patients fulfilling the diagnostic criteria for FSHD with 200 control subj...
متن کاملFacioscapulohumeral 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...
