Clinical expression of facioscapulohumeral muscular dystrophy in carriers of 1-3 D4Z4 reduced alleles: experience of the FSHD Italian National Registry.
OBJECTIVES Facioscapulohumeral muscular dystrophy type 1 (FSHD1) has been genetically linked to reduced numbers (≤ 8) of D4Z4 repeats at 4q35. Particularly severe FSHD cases, characterised by an infantile onset and presence of additional extra-muscular features, have been associated with the shortest D4Z4 reduced alleles with 1-3 repeats (1-3 DRA). We searched for signs of perinatal onset and e...
متن کاملUK 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 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...

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...
