Muscular dystrophies (MD) are a group of hereditary diseases marked by progressive muscle loss, leading to weakness and degeneration of skeletal muscles. These conditions often result from structural defects in the Dystrophin-Glycoprotein Complex (DGC), as seen in Duchenne Muscular Dystrophy (DMD) and Becker Muscular Dystrophy (BMD). Since MDs currently have no cure, research has focused on identifying potential therapeutic targets to improve patients' quality of life.

Skeletal muscles account for ~30-40% of the total weight of human body and are responsible for its most important functions, including movement, respiration, thermogenesis, and glucose and protein metabolism. Skeletal muscle damage negatively impacts the whole-body functioning, leading to deterioration of the quality of life and, in severe cases, death. Therefore, timely diagnosis and therapy for skeletal muscle dysfunction are important goals of modern medicine.

The patient was a 33-year-old woman with no family history of a similar disorder. At one year of age, she exhibited scoliosis and respiratory failure, necessitating a tracheostomy performed at 5 years of age (1990s). During that time, the patient was provisionally diagnosed with "non-Fukuyama congenital muscular dystrophy" via muscle biopsy.

In Japan, there are no nationwide guidelines for presymptomatic testing for hereditary neuromuscular diseases. Although each institution has been dealing with this situation by using their own procedures to date, it is necessary to develop a standardized guidelines based on the Japanese medical system, because the development of disease-modifying therapies has progressed, and we are entering an era in which early diagnosis and early treatment are necessary. The guidelines presented here were devised by the Committee on Medical Genetics of the Japan Neurological Society.

The severity of spinal muscular atrophy (SMA) is inversely correlated with the number of survival of motor neuron 2 (SMN2) copies an individual has. This observational, retrospective analysis of natural history data included untreated individuals with a genetic diagnosis of types 1-3 SMA and stratified disease-related characteristics by SMN2 copy number. The outcomes investigated were time to: death, permanent ventilation, respiratory support, feeding support, scoliosis surgery, and achievement and loss of motor milestones.
