Biomarkers for assessing fatty acid oxidation deficiencies
French specialists in metabolic diseases have sought to gain a better understanding of the severity and course of patients suffering from fatty acid oxidation disorder (FAOD), some of whom have muscular manifestations: 27 patients aged over 6 years with different forms of FAOD were included in this retrospective study, 10 with LCHAD deficiency, 6 with … [Read more]
The first digital functional assessment tool validated in DMD
The international consortium of researchers, including experts from the Institute of Myology, which developed SV95C, a digital parameter for the functional evaluation of Duchenne muscular dystrophy (DMD), has announced its adoption by the European Medicines Agency (EMA) as a primary endpoint in therapeutic trials: this assessment is based on the analysis of information transmitted by … [Read more]
Gene therapy improves cardiomyopathy in Danon disease: results of an initial phase I trial
In the USA, a Phase I trial in Danon’s disease assessed the safety and efficacy of a gene therapy, RP-A501, consisting of intravenous injection of a recombinant serotype 9 adeno-associated virus containing the LAMP2B transgene over a follow-up period of 2 to 4.5 years. It included seven male patients (two aged 11 and 14 and … [Read more]

A mutation in HSPB8 leads to axial and proximal myofibrillar myopathy beginning in childhood
While mutations in HSPB8 have been associated with distal hereditary motor neuropathy (dHMN2A) or Charcot-Marie-Tooth disease type 2L, five variants (including four affecting the last exon) of this gene have been linked to a distal form of myopathy beginning in adulthood. A Chinese team reports a first case of an 18-year-old girl with : a … [Read more]
The p.D207V mutation is correlated with a less severe form of GNE myopathy
A retrospective Chinese study of 83 patients with GNE myopathy compared the evolution of 40 carriers of the p.D207V mutation in the gene in question with that of 43 carriers of another mutation: the age of onset of the disease was 27 years for the former versus 24 years for the latter; carriers of the … [Read more]
A new gene, HMGCS1, causes stiff spine syndrome
An international consortium has reported the discovery of a new gene responsible for rigid spine syndrome (RSS): several families with an RSS phenotype but no mutation in the SELENON gene have been studied, either in whole exome or whole genome, bi-allelic variants of the HMGCS1 gene were identified in five patients from four unrelated families, … [Read more]
