A founder effect identified in South Indian patients with beta-sarcoglycanopathy
Beta sarcoglycanopathy is one of the four forms of limb-girdle myopathy associated with sarcoglycan deficiency. Indian clinicians have just identified an outbreak of this disease in their country: 14 patients from 13 unrelated families in southern India (the states of Karnataka, Tamil Nadu and Andra Pradesh) were diagnosed with limb-girdle muscular dystrophy with beta-sarcoglycan deficiency, … [Read more]
A comparative study of the extra-muscular manifestations of anti-synthetase syndrome and dermatomyositis
As part of the MYONET patient registry, a consortium of clinicians compared the clinical and biological data of adult patients with either antisynthetase syndrome (ASys) or dermatomyositis (DM): 1054 patients were included in the study (405 with ASys and 649 with DM), One third of patients in the ASys cohort had skin manifestations suggestive of … [Read more]

Clear mitochondrial abnormalities and dermatomyositis: a case report
A team of Italian clinicians report the observation of a 77-year-old woman presenting with a classic picture of dermatomyositis (DM) with positive anti-Mi-2 autoantibodies: study of a biopsy muscle fragment nevertheless revealed very marked abnormalities in the mitochondria, in addition to the characteristic lesions usually found in DM (extensive perifascicular atrophy), the patient did not … [Read more]
Russian success with tofacitinib in FOP
Treatment with tofacitinib 5 mg twice daily was evaluated in 13 children with chronic fibrodysplasia ossificans aged 2.2 to 19.6 years: it reduced the mean number of heterotopic ossification flare-ups from 10 in the 12 months preceding the start of treatment to 0 in the 24 months that followed. thirty-one per cent of patients showed … [Read more]

FSHD: searching for the ideal biomarker
British and Dutch researchers have joined forces to discover a possible biological marker for facioscapulohumeral muscular dystrophy (FSHD): in view of the disappointing and/or contradictory results of studies of DUX4 gene expression in FSHD myopathy, the researchers focused their attention on genes repressed by PAX7, another gene involved in myogenesis and also interacting with DUX4, … [Read more]
Poor quality sleep in CMT?

The authors therefore recommend assessing sleep in people with CMT, as well as related factors such as fatigue and … [Read more]
First clinical results of a gene therapy for the treatment of FKRP-related LGMD
The initial results of the ATA-100 gene therapy clinical trial for the treatment of limb-girdle muscular dystrophy linked to the FKRP gene (LGMD2I/R9) were presented at the ESGCT congress in Brussels on 27 October. This multicentre Phase 1b/2b trial is designed to assess the safety and efficacy of a gene therapy combining an AAV vector … [Read more]
Camptocormia and a dropped head are poor prognostic factors in certain forms of myositis
An international consortium of clinicians coordinated by the Strasbourg Reference Centre looked at patients with inflammatory myopathy with regard to two uncommon clinical signs: camptocormia and/or head droop syndrome in 49 patients with inflammatory myopathy, their clinical and biological data were compared with those of 98 patients with inflammatory myopathy but without these two signs, … [Read more]
