Generation of iMyoblasts from Human Induced Pluripotent Stem Cells

Bio-Protocol, 2022
Skeletal muscle stem cells differentiated from human-induced pluripotent stem cells (hiPSCs) serve as a uniquely promising model system for investigating human myogenesis and disease pathogenesis, and for the development of gene editing and regenerative ...

Linker molecules between laminins and dystroglycan ameliorate laminin-alpha2-deficient muscular dystrophy at all disease stages [PDF]

, 2007
Mutations in laminin-alpha2 cause a severe congenital muscular dystrophy, called MDC1A. The two main receptors that interact with laminin-alpha2 are dystroglycan and alpha7beta1 integrin.

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 ...

Streamlining Diagnosis of Bardet–Biedl Syndrome: New Diagnostic Algorithm With Updated Criteria

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Considerable advances have been made in our understanding of Bardet–Biedl syndrome (BBS), particularly in its core clinical features and molecular genetics, warranting an update to the existing diagnostic criteria framework. Using a rigorous, evidence‐based, and consensus‐driven process, a multidisciplinary group of international experts and ...

Genetic analysis of limb girdle muscular dystrophy and Miyoshi myopathy [PDF]

, 2003
The autosomal recessive muscular dystrophies encompass limb girdle muscular dystrophy (LGMD) and Miyoshi myopathy (MM), which can show clinical and genetic overlap.

Evaluation of quantitative muscle MRI and an intelligent phenotyping housing system as advanced phenotyping methods in a mouse model of calpain 3‐deficient muscular dystrophy

Animal Models and Experimental Medicine, EarlyView.
We applied quantitative MRI of the lower limb and automated home‐cage phenotyping to a mouse model of calpainopathy to detect early disease changes. At 15 months, calpain 3‐deficient mice showed increased water T2 values correlating with immune cell infiltration in the soleus and gastrocnemius muscles, while assessment of motor activity revealed only ...

AGRN‐, LRP4‐, MUSK‐Related CMS: Clinical, Neurophysiological, Morphological, Genetic and Pathological Mechanisms

Muscle &Nerve, EarlyView.
ABSTRACT Congenital myasthenic syndromes (CMS) are inherited disorders caused by mutations in genes encoding proteins essential for neuromuscular junction (NMJ) function. Pathogenic variants have been identified in more than 35 genes, underscoring the complexity of synaptic biology and the wide range of mechanisms that can compromise neuromuscular ...

Exploiting the full power of temporal gene expression profiling through a new statistical test: Application to the analysis of muscular dystrophy data

, 2006
Background: The identification of biologically interesting genes in a temporal expression profiling dataset is challenging and complicated by high levels of experimental noise.

Dysferlin at transverse tubules regulates Ca2+ homeostasis in skeletal muscle

Frontiers in Physiology, 2014
The class of muscular dystrophies linked to the genetic ablation or mutation of dysferlin, including Limb Girdle Muscular Dystrophy 2B (LGMD2B) and Miyoshi Myopathy (MM), are late-onset degenerative diseases.

The Differing Phenotypes of the Three Most Common Postsynaptic Congenital Myasthenic Syndromes Governed by Their Underlying Molecular Pathogenic Mechanisms

Muscle &Nerve, EarlyView.
ABSTRACT The congenital myasthenic syndromes are rare disorders of impaired signal transmission at the neuromuscular junction. Despite next generation sequencing facilitating the identification of variants in myasthenic‐associated genes, these variants are frequently of unknown significance and the clinical diagnosis can be delayed.
