Novel diagnostic features of dysferlinopathies [PDF]

Muscle & Nerve, 2010
AbstractReports of dysferlinopathy have suggested a clinically heterogeneous group of patients. We identified specific novel molecular and phenotypic features that help distinguish dysferlinopathies from other forms of limb‐girdle muscular dystrophy (LGMD). A detailed history, physical exam, and protein and mutation analysis of genomic DNA was done for

Dysferlinopathy misdiagnosed with juvenile polymyositis in the pre-symptomatic stage of hyperCKemia: a case report and literature review

BMC Medical Genomics, 2022
Background Dysferlinopathy encompasses a group of rare muscular dystrophies caused by recessive mutations in the DYSF gene. The phenotype ranges from asymptomatic elevated serum creatine kinase (hyperCKemia) to selective and progressive involvement of ...

Elevated Ca2+ at the triad junction underlies dysregulation of Ca2+ signaling in dysferlin-null skeletal muscle

Frontiers in Physiology, 2022
Dysferlin-null A/J myofibers generate abnormal Ca2+ transients that are slightly reduced in amplitude compared to controls. These are further reduced in amplitude by hypoosmotic shock and often appear as Ca2+ waves (Lukyanenko et al., J. Physiol., 2017).

Dual Effects of Exercise in Dysferlinopathy [PDF]

The American Journal of Pathology, 2013
Dysferlinopathy refers to a group of autosomal recessive muscular dystrophies due to mutations in the dysferlin gene causing deficiency of a membrane-bound protein crucially involved in plasma membrane repair. The condition is characterized by marked clinical heterogeneity, the different phenotypes/modes of presentation being unrelated to the genotype.

Genetic screening of an endemic mutation in the DYSF gene in an isolated, mountainous population in the Republic of Dagestan

Molecular Genetics & Genomic Medicine, 2023
Background Dysferlinopathy has a high prevalence in relatively isolated ethnic groups where consanguineous marriages are characteristic and/or the founder effect exists.

Minimal expression of dysferlin prevents development of dysferlinopathy in dysferlin exon 40a knockout mice

Acta Neuropathologica Communications, 2023
Dysferlin is a Ca2+-activated lipid binding protein implicated in muscle membrane repair. Recessive variants in DYSF result in dysferlinopathy, a progressive muscular dystrophy.

Myositis mimics

Indian Journal of Rheumatology, 2021
Proximal muscle weakness in children, as well as adults, can be the presenting feature of a wide range of diseases including but not limited to the idiopathic inflammatory myopathies, muscle dystrophies, metabolic, endocrine, and drug-induced myopathies.

A rare case of dysferlinopathy with paternal isodisomy for chromosome 2 determined by exome sequencing

Molecular Genetics & Genomic Medicine, 2023
Background Dysferlinopathies are autosomal recessive muscular dystrophies resulting from defects in DYSF (MIM: 603009), which is located on chromosome 2p13 and encodes the dysferlin protein. Methods We performed exome sequencing and subsequent trio‐based
