Female carriers of Duchenne muscular dystrophy (DMD) are usually asymptomatic. However, 2.5-7.8% of them may present muscle symptoms and cardiomyopathy, attributed to a reduced production of dystrophin, probably because of skewed patterns of X-chromosome inactivation (XCI). To evaluate the role of XCI in symptomatic (at muscle or heart level) and(More)
OBJECTIVE Dilated cardiomyopathy (DCM) is a major complication and leading cause of death in Duchenne muscular dystrophy (DMD). DCM onset is variable, suggesting modifier effects of genetic or environmental factors. We aimed to determine if polymorphisms previously associated with age at loss of independent ambulation (LoA) in DMD (rs28357094 in the SPP1(More)
The dystroglycanopathies, which are caused by reduced glycosylation of alpha-dystroglycan, are a heterogeneous group of neurodegenerative disorders characterized by variable brain and skeletal muscle involvement. Recently, mutations in TMEM5 have been described in severe dystroglycanopathies. We present the clinical, molecular and neuroimaging features of(More)
