Abstract
INTRODUCTION Patients with severe neuromuscular disease (sNMD) are considered at high risk of severe COVID-19. Muscle tissue is often replaced by fibroadipose tissue in these diseases whereas the new mRNA-based vaccines are injected intramuscularly. We aimed at evaluating the efficacy of two injections associated with a booster injection of mRNA vaccine in these patients. METHODS We performed an observational, prospective, single-centre study to investigate the level of anti-S antibodies (Abs) and their neutralization activity at weeks 6 (W6) and 24 (W24) after two injections of mRNA-1273 vaccine and at weeks 12 (BW12) and 29 (BW29) after a booster injection of BNT162b2 vaccine in patients with sNMD. RESULTS Thirty-three patients with sNMD were included. At W6, 30 patients (90.1%) showed a protective serum level of specific anti-S Abs with a strong neutralization capacity. We observed a decline over time: only 12 patients (36.3%) retained anti-S Abs levels considered as protective at W24. The neutralization activity remained above the cut off in 23 (69.7%). The booster vaccination restored robust neutralization activity for all analysed 22 patients (100%) at BW12, which was maintained without any significant drop at BW29 (16). No severe adverse event was reported in this cohort and none of the 33 patients developed symptomatic COVID-19 over one year. CONCLUSIONS This study provides evidence that most sNMD patients receiving two injections of COVID-19 mRNA-based vaccines develop a strong humoral response after vaccination. A decline over time was observed but a single booster injection restores a long-term immunity. Moreover, no safety issues were observed.

Abstract
BACKGROUND Mitochondrial myopathies are regulated by two genomes: the nuclear DNA, and the mitochondrial DNA. While, so far, most studies have dealt with mitochondrial myopathies due to deletions or point mutations in the mitochondrial DNA, a new field of investigation is that of syndromes due to mutations in the nuclear DNA. These latter disorders have mendelian inheritance. RESULTS Three representative cases have been selected: one with COX deficiency and a Leigh syndrome due to a SURF1 gene mutation, one due to a defect of Coenzyme Q synthesis and one with dominant optic atrophy due to a mutation in the OPA1 gene. CONCLUSIONS Future developments will show that many neurodegenerative disorders are due to mutations of nuclear genes controlling mitochondrial function, fusion and fission.

Abstract
BACKGROUND Limb girdle muscular dystrophy type 2A (LGMD2A) is characterised by wide variability in clinical features and rate of progression. Patients with two null mutations usually have a rapid course, but in the remaining cases (two missense mutations or compound heterozygote mutations) prognosis is uncertain. METHODS We conducted what is to our knowledge the first systematic histopathological, biochemical and molecular investigation of 24 LGMD2A patients, subdivided according to rapid or slow disease progression, to determine if some parameters could correlate with disease progression. RESULTS We found that muscle histopathology score and the extent of regenerating and degenerating fibres could be correlated with the rate of disease course when the biochemical and molecular data do not offer sufficient information. Comparison of clinical and muscle histopathological data between LGMD2A and four other types of LGMD (LGMD2B-E) also gave another important and novel result. We found that LGMD2A has significantly lower levels of dystrophic features (ie degenerating and regenerating fibres) and higher levels of chronic changes (ie lobulated fibres) compared with other LGMDs, particularly LGMD2B. These results might explain the observation that atrophic muscle involvement seems to be a clinical feature peculiar to LGMD2A patients. CONCLUSIONS Distinguishing patterns of muscle histopathological changes in LGMD2A might reflect the effects of a disease-specific pathogenetic mechanism and provide clues complementary to genetic data.

Abstract
Limb girdle muscular dystrophy (LGMD) type 2A (LGMD2A) is caused by mutations in the CAPN3 gene encoding for calpain-3, a muscle specific protease. While a large number of CAPN3 gene mutations have already been described in calpainopathy patients, the diagnosis has recently shifted from molecular genetics towards biochemical assay of defective protein. However, an estimate of sensitivity and specificity of protein analysis remains to be established. Thus, we first correlated protein and molecular data in our large LGMD2A patient population. By a preliminary immunoblot screening for calpain-3 protein of 548 unclassified patients with various phenotypes (LGMD, myopathy, or elevated levels of serum creatine kinase [hyperCKemia]), we selected 208 cases for CAPN3 gene mutation analysis: 69 had protein deficiency and 139 had normal expression. Mutation search was conducted using SSCP, denaturing high performance liquid chromatography (DHPLC), amplification refractory mutation system (ARMS-PCR), and direct sequencing methods. We identified 58 LGMD2A mutant patients: 46 (80%) had a variable degree of protein deficiency and 12 (20%) had normal amount of calpain-3. We calculated that the probability of having LGMD2A is very high (84%) when patients show a complete calpain-3 deficiency and progressively decreases with the amount of protein; this new data offers an important tool for genetic counseling when only protein data are available. A total of 37 different CAPN3 gene mutations were detected, 10 of which are novel. In our population, 87% of mutant alleles were concentrated in seven exons (exons 1, 4, 5, 8, 10, 11, and 21) and 61% correspond to only eight mutations, indicating the regions where future molecular analysis could be restricted. This study reports the largest collection of LGMD2A patients so far in which both protein and gene mutations were obtained to draw genotype-protein-phenotype correlations and provide insights into a critical protein domain.
