Duchenne muscular dystrophy carrier detection has been performed by using probes XJ1.1 (intragenic probe) and probe 754 for a girl. The carrier probability was estimated by means of a computer program GenRisk combining pedigree and DNA-probe data and turned out to be 95%.

Background And Purpose: This study was an open-label, dose-escalation, phase 1 clinical trial to determine the safety and dose of EN001 for patients with Duchenne muscular dystrophy (DMD). EN001, developed by ENCell, are allogeneic early-passage Wharton's jelly-derived mesenchymal stem cells that originate at the umbilical cord, with preclinical studies demonstrating their high therapeutic efficacy for DMD.
Methods: This phase 1 clinical trial explored the safety and tolerability of EN001 as a potential treatment option for patients with DMD.

Introduction: A 20 kDa fragment at the N-terminus of titin is highly excreted in the urine of patients with Duchenne muscular dystrophy (DMD), making urine titin a prominent biomarker for muscle breakdown. This N-terminal fragment is presumed to be a product of degradation by a protein-degrading enzyme, calpain 3; however, whether calpain 3 is required remains unclear. We aimed to determine whether urine titin elevation occurs in the absence of calpain 3.

Background: Reduced forced vital capacity (FVC) is associated with morbidity and mortality in individuals with Duchenne muscular dystrophy (DMD). Non-invasive ventilation (NIV) is often prescribed for the treatment of sleep-disordered breathing (SDB), and chronic respiratory insufficiency. Despite the common practice of initiating NIV later in the progression of DMD, the factors influencing FVC subsequent to the commencement of NIV remain unclear.

: X-linked dystrophinopathies are a group of neuromuscular diseases caused by pathogenic variants in the gene (MIM *300377). Duchenne muscular dystrophy (DMD; MIM #310200) is the most common inherited muscular dystrophy. : We screened datasets of 403 male, genetically confirmed X-linked dystrophinopathy patients and identified 13 pathogenic variants of the gene that have not been described in the literature thus far.
