OBJECTIVE To characterize the presence and behavior of the dystrophinopathic myocardial damage in female carriers of a gene defect at the Xp21 locus of the X chromosome that causes Duchenne and Becker muscular dystrophies (DMD and BMD). DESIGN Cohort study from April 1, 1985, to April 30, 1995, with cardiologic follow-up performed yearly for a minimum of(More)
The BIO14.6 hamster is a widely used model for autosomal recessive cardiomyopathy. These animals die prematurely from progressive myocardial necrosis and heart failure. The primary genetic defect leading to the cardiomyopathy is still unknown. Recently, a genetic linkage map localized the cardiomyopathy locus on hamster chromosome 9qa2.1-b1, excluding(More)
To assess the incidence, nature and evolution of cardiac disease in Duchenne muscular dystrophy, 328 patients were studied between 1976 and 1987 for periods varying from 3 to 11 years. Patients underwent regular clinical examination, electrocardiography, echocardiography and radiological assessment. Pre-clinical cardiac involvement was found in 25% of(More)
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)
Clinical, electrocardiographic, echocardiographic and other instrumental examinations were performed on 233 persons primarily seeking genetic advice about the Duchenne/Becker gene in order to reveal the incidence of dystrophic cardiomyopathy in a population of females with a close relationship with patients suffering from Duchenne or Becker muscular(More)
We have raised an anti-emerin polyclonal antibody against a fusion protein encompassing most of the hydrophilic portion of emerin. Using this antibody, we have analyzed emerin expression in Emery-Dreifuss muscular dystrophy (EDMD) patients and controls, by immunocytochemistry, in skeletal muscle and skin, and by immunoblot, in peripheral blood mononuclear(More)
Despite the recent progress in the broad-scaled analysis of proteins in body fluids, there is still a lack in protein profiling approaches for biomarkers of rare diseases. Scarcity of samples is the main obstacle hindering attempts to apply discovery driven protein profiling in rare diseases. We addressed this challenge by combining samples collected within(More)
TRIM32 belongs to a large family of proteins characterized by a tripartite motif, possibly involved in the ubiquitination process, acting as an E3 ligase. In addition, TRIM32 has six NHL repeats with putative interaction properties. A homozygous mutation at the third NHL repeat (D487N) has been found in patients with limb girdle muscular dystrophy 2H(More)
The EuroBioBank (EBB) network (www.eurobiobank.org) is the first operating network of biobanks in Europe to provide human DNA, cell and tissue samples as a service to the scientific community conducting research on rare diseases (RDs). The EBB was established in 2001 to facilitate access to RD biospecimens and associated data; it obtained funding from the(More)
