Genomic reanalysis of a pan-European rare-disease resource yields new diagnoses.

Genetic diagnosis of rare diseases requires accurate identification and interpretation of genomic variants. Clinical and molecular scientists from 37 expert centers across Europe created the Solve-Rare Diseases Consortium (Solve-RD) resource, encompassing clinical, pedigree and genomic rare-disease data (94.5% exomes, 5.

Association between age at loss of ambulation and cardiac function in adults with Duchenne muscular dystrophy.

Cardiomyopathy is a common co-morbidity in individuals with Duchenne muscular dystrophy (DMD). This retrospective single centre study investigated the relationship between age at loss of ambulation (LOA) and late stage left ventricular ejection fraction (LVEF) in 84 individuals (> 16 years old) with DMD taking glucocorticoid and ACE inhibitors treatment. Regression analyses showed a positive correlation between later age at LOA and higher LVEF in adulthood (linear regression estimate 1.

Clinical and imaging spectrum of non-congenital dominant ACTN2 myopathy.

Background: Alpha-actinin-2, a protein with high expression in cardiac and skeletal muscle, is located in the Z-disc and plays a key role in sarcomere stability. Mutations in ACTN2 have been associated with both hypertrophic and dilated cardiomyopathy and, more recently, with skeletal myopathy.

Methods: Genetic, clinical, and muscle imaging data were collected from 37 patients with an autosomal dominant ACTN2 myopathy belonging to 11 families from Spain and Belgium.

Safety and Efficacy of IV Onasemnogene Abeparvovec for Pediatric Patients With Spinal Muscular Atrophy: The Phase 3b SMART Study.

Background And Objectives: Safety and efficacy of IV onasemnogene abeparvovec has been demonstrated for patients with spinal muscular atrophy (SMA) weighing <8.5 kg. SMART was the first clinical trial to evaluate onasemnogene abeparvovec for participants weighing 8.
