Laminopathies are a heterogeneous group of diseases that are caused by mutations in the nuclear envelope proteins lamins A and C. Laminopathies include dilated cardiomyopathy, Emery-Dreifuss muscular dystrophy, and familial partial lipodystrophy. Despite their near-ubiquitous expression, most laminopathies involve highly tissue-specific phenotypes, often affecting skeletal and cardiac muscle. T...

Background: Mutations in the gene encoding the nuclear membrane protein lamin A/C have been associated with at least 7 distinct diseases including dilated cardiomyopathy with conduction system disease, autosomal dominant Emery Dreifuss Muscular Dystrophy, limb girdle muscular dystrophy, Charcot Marie Tooth, Mandibuloacral dysplasia, lipodystrophy and progeria. Methods: We used mutation detectio...

The laminopathies are a diverse group of conditions caused by mutations in the LMNA gene (MIM*150330). LMNA encodes the nuclear envelope proteins lamin A and lamin C by utilization of an alternative splice site in exon 10. The human LMNA gene was identified in 1986 but it was another 13 years before it was found to be the causative gene for a disease, namely Emery Dreifuss muscular dystrophy. S...

Congenital Muscular Dystrophies are a heterogeneous group of muscular disorders defined as early onset muscle weakness and progressive course associated to dystrophic features at muscle biopsy. CMDs related to lamina A/C gene (LMNA) defect include different phenotypes that can be classified as i) severe phenotype with generalized muscular weakness and contractures by birth, ii) ‘dropped head’ p...

Muscular dystrophies are a heterogeneous group of disorders linked to defects in 20-30 different genes. Mutations in the genes encoding a pair of nuclear envelope proteins, emerin and lamin A/C, have been shown to cause the X-linked and autosomal forms respectively of Emery-Dreifuss muscular dystrophy. A third form of muscular dystrophy, limb girdle muscular dystrophy 1b, has also been linked t...

Resumo O presente artigo analisa a relação entre as empresas e ditadura brasileira imposta com o golpe de 1964. No entanto, não tratamos - como é mais comum das relações apoio, composição favorecimento grupos econômicos regime, mas sim organizações empresariais que foram perseguidas penalizadas pelas ações do aparelho Estado após golpe. Para proceder à abordagem, utilizamos memórias, testemunho...

There are roughly 14 distinct heritable autosomal dominant diseases associated with mutations in lamins A/C, including Emery-Dreifuss muscular dystrophy (EDMD). The mechanical model proposes that the lamin mutations change the mechanical properties of muscle nuclei, leading to cell death and tissue deterioration. Here, we developed an experimental protocol that analyzes the effect of disease-li...

BACKGROUND Emery-Dreifuss muscular dystrophy, caused by EMD gene mutations, is characterized by humeroperoneal muscular dystrophy, joint contractures, and conduction defects and is often associated with sudden cardiac death, even without prior cardiac symptoms. OBJECTIVE To describe the clinical and molecular features of 2 patients with limb-girdle muscular dystrophy with mutations in EMD. ...

Introduction Autosomal dominant Emery-Dreifuss muscular dystrophy (AD-EDMD) is rare compared with other forms of muscular dystrophy and is characterized by cardiac conduction defects. Here, we present the case of a patient diagnosed with AD-EDMD during the first trimester of pregnancy who developed acute preeclampsia and subsequently, congestive heart failure (CHF) following cesarean section. C...
