AI Article Synopsis

  • This article reviews essential concepts of genetic treatment for neuromuscular disorders and highlights the critical role of genetic testing in gene therapy applications.
  • Gene therapies are now available for certain conditions, with innovations like exon-skipping for Duchenne muscular dystrophy and promising results from microdystrophin gene replacement nearing trial completion.
  • Diagnosing muscle disorders through genetic testing is vital for treatment guidance, as different genetic conditions require tailored approaches for effective therapy.

Article Abstract

Purpose Of Review: This article discusses the foundational concepts of genetic treatment strategies employed in neuromuscular medicine, as well as the importance of genetic testing as a requirement for applying gene-based therapy.

Recent Findings: Gene therapies have become a reality for several neuromuscular disorders. Exon-skipping and (in Europe) ribosomal read-through approaches are currently available to a subset of patients with Duchenne muscular dystrophy. Microdystrophin gene replacement has shown promise and is nearing the final stages of clinical trials. Numerous gene-based therapies for other muscular dystrophies and congenital myopathies are progressing toward approval as well.

Summary: Muscular dystrophies and congenital myopathies are a heterogenous group of hereditary muscle disorders. Confirming a diagnosis with genetic testing is not only critical for guiding management, but also an actual prerequisite for current and future gene therapies. Recessive loss-of-function or dominant haploinsufficiency disorders may be treated with gene replacement strategies, whereas dominant negative and toxic gain-of-function disorders are best addressed with a variety of knockdown approaches. It is important to recognize that many therapeutics are mutation specific and will only benefit a subset of individuals with a specific disease.

Background And Purpose: Pathogenic variants in the RYR1 gene have been associated with a variety of conditions, ranging from congenital myopathy to adult manifestations. Our aim was to characterize the p.Leu2286Val variant in 17 Basque patients, to accurately determine its correlation with clinical features and to explore the possible founder effect of the variant.

Introduction: Each year the number of combined heart-liver transplants (HLT) increases, with two distinct patient populations proceeding down this pathway. The first are patients with congenital heart disease (CHD), most commonly single ventricle patients palliated with Fontan. The second group are those with long standing congestive hepatopathy, amyloidosis, hemochromatosis, or alcohol induced myopathies and liver disease.

Neuromuscular disorders (NMD) with neonatal or early infantile onset are usually severe and differ in symptoms, complications, and treatment options. The establishment of a diagnosis relies on the combination of clinical examination, morphological analyses of muscle biopsies, and genetic investigations. Here, we re-evaluated and classified a unique collection of 535 muscle biopsies from NMD infants aged 0-6 months examined over a period of 52 years.

Sporadic late-onset nemaline rod myopathy is a rare, acquired, sub-acute, adult-onset myopathy characterized by proximal muscle weakness and nemaline rods in the myofibers. In contrast to its congenital form, the prevalence in adult population is comparatively rare. Herein, we report a case of 60-year-old male who presented with insidious onset proximal muscle weakness with myopathic pattern on electromyography.

Congenital titinopathies reported to date show autosomal recessive inheritance and are caused by a variety of genomic variants, most of them located in metatranscript (MTT)-only exons. The aim of this study was to describe additional patients and establish robust genotype-phenotype associations in titinopathies. This study involved analyzing molecular, clinical, pathological, and muscle imaging features in 20 patients who had at least one pathogenic or likely pathogenic variant in MTT-only exons, with onset occurring antenatally or in the early postnatal stages.
