Muscle protein analysis in the detection of heterozygotes for recessive limb girdle muscular dystrophy type 2B and 2E

Neuromuscular Disorders, 2006
The diagnosis of isolated heterozygotes for recessive LGMD is quite difficult because no specific biochemical or protein assays are available, and the molecular analysis is not feasible due to the wide genetic heterogeneity. We investigated a series of definite heterozygotes for different forms of LGMD to determine whether the carrier status will ...

Dysferlin aggregation in limb‐girdle muscular dystrophy type 2B/myoshi myopathy necessitates mutational screen for diagnosis

Muscle & Nerve, 2013
Introduction: Diagnosis of the limb‐girdle muscular dystrophies (LGMDs) has been facilitated by the use of immunofluorescence microscopy, Western blot analysis, and rapid genetic testing. Methods: We identified 7 patients with LGMD2B or Miyoshi myopathy (MM) phenotypes and performed detailed history, physical examination, and mutation analyses of ...

A novel multi‐exon deletion in the dysferlin gene of a limb‐girdle muscular dystrophy type 2B Filipino patient

Neurology and Clinical Neuroscience, 2020
AbstractWe present a 34‐year‐old woman, from Philippines, diagnosed limb‐girdle muscular dystrophy type 2B with compound heterozygous nonsense mutation W1478* and novel deletion of exons 43‐46 of the dysferlin gene. These loss‐of‐function mutations do not seem to be predictive of a severer clinical course.

A gene related to Caenorhabditis elegans spermatogenesis factor fer-1 is mutated in limb-girdle muscular dystrophy type 2B

Nature Genetics, 1998
The limb-girdle muscular dystrophies are a genetically heterogeneous group of inherited progressive muscle disorders that affect mainly the proximal musculature, with evidence for at least three autosomal dominant and eight autosomal recessive loci. The latter mostly involve mutations in genes encoding components of the dystrophin-associated complex ...

[A patient with limb girdle muscular dystrophy type 2B (LGMD2B) manifesting cardiomyopathy].

Rinsho shinkeigaku = Clinical neurology, 2004
A 57-year-old woman first noticed difficulty in walking at the age of 34 years, and since then muscle wasting and weakness in the lower limbs and proximal portion of the upper limbs had progressed slowly. Serum CK was elevated. Immunohistochemical study of the biceps brachii muscle showed deficiency of dysferlin in sarcolemma, and the dysferlin gene ...

P1.20 Clinical features of limb-girdle muscular dystrophy type 2B with the c.2997G > T mutation

Neuromuscular Disorders, 2010
Background: Dysferlinopathy refers to a group of autosomal recessive muscular dystrophies caused by mutations in DYSF, which encodes dysferlin working for calcium-dependent membrane repair in skeletal muscle. The disease group includes three distinct disorders; limb-girdle muscular dystrophy type 2B (LGMD2B), Miyoshi myopathy (MM) and distal anterior ...

[Analysis of DYSF gene mutations in two pedigrees affected with limb-girdle muscular dystrophy type 2B].

Zhonghua yi xue yi chuan xue za zhi = Zhonghua yixue yichuanxue zazhi = Chinese journal of medical genetics, 2019
To analyze mutations of DYSF gene in two pedigrees affected with limb-girdle muscular dystrophy 2B (LGMD-2B).Genomic DNA was extracted from peripheral blood samples of the two probands and unaffected family members. Variant sites were screened by next-generation sequencing using gene panel as well as Sanger sequencing.Four pathogenic mutations of the ...

[Mutational and clinical features of Japanese patients with dysferlinopathy (Miyoshi myopathy and limb girdle muscular dystrophy type 2B)].

Rinsho shinkeigaku = Clinical neurology, 2006
Mutations in the dysferlin gene cause both Miyoshi myopathy (MM) and limb girdle muscular dystrophy 2B (LGMD2B). We examined patients with dysferlinopathy in Japan, and identified 28 and 12 different mutations respectively in MM and LGMD2B patients. The mean age at onset of the patients with MM was 22 +/- 9 years (range 12-48 years) and that of the ...
