Abstract
Mitochondrial diseases are genetic disorders impairing mitochondrial functions. Here we describe a patient with a neurodegenerative condition associated with myopia, bilateral sensorineural hearing loss and motor disorders. Brain MRIs showed major cortico-subcortical and infra-tentorial atrophies, as well as intracerebral iron accumulation and central calcifications, compatible with a NBIA-like phenotype. Mitochondrial DNA analysis revealed an undescribed variant: m.8091G>A in the MT-CO2 gene, associated with a complex IV deficiency and a decrease of the mitochondrial respiratory chain capabilities. We report here this pathogenic variant, associated with a NBIA-like phenotype.

Abstract
AIMS NTRK gene fusions have been described in a wide variety of central nervous system (CNS) and soft tissue tumours, including the provisional tumour type 'spindle cell neoplasm, NTRK-rearranged' (SCN-NTRK), added to the 2020 World Health Organisation Classification of Soft Tissue Tumours. Because of histopathological and molecular overlaps with other soft tissue entities, controversy remains concerning the lineage and terminology of SCN-NTRK. METHODS AND RESULTS This study included 16 mesenchymal tumours displaying kinase gene fusions (NTRK fusions and one MET fusion) initially diagnosed as infantile fibrosarcomas (IFS), SCN-NTRK and adult-type fibrosarcomas from the soft tissue, viscera and CNS. We used immunohistochemistry, DNA methylation profiling, whole RNA-sequencing and ultrastructural analysis to characterise them. Unsupervised t-distributed stochastic neighbour embedding analysis showed that 11 cases (two CNS tumours and nine extra-CNS) formed a unique and new methylation cluster, while all tumours but one, initially diagnosed as IFS, clustered in a distinct methylation class. All the tumours except one formed a single cluster within the hierarchical clustering of whole RNA-sequencing data. Tumours from the novel methylation class co-expressed CD34 and S100, had variable histopathological grades and frequently displayed a CDKN2A deletion. Ultrastructural analyses evidenced a myofibroblastic differentiation. CONCLUSIONS Our findings confirm that SCN-NTRK share similar features in adults and children and in all locations combine an infiltrative pattern, distinct epigenetic and transcriptomic profiles, and ultrastructural evidence of a myofibroblastic lineage. Further studies may support the use of new terminology to better describe their myofibroblastic nature.

Abstract
The neuropathological changes of limbic-predominant age-related TDP-43 encephalopathy (LATE) are frequent in the aged population and are now recognized as a cause of memory impairment. However, it remains unknown if this proteinopathy is also present in other primate species. We thus investigated the presence and distribution of TDP-43 pathology in the hippocampus and amygdala of 7 aged memory-impaired rhesus macaques (Macaca mulatta, 18-32 years old) from 2 different cohorts. While present in an FTLD-TDP case used as a positive control for immunostaining, we found no TDP-43 or phosphorylated TDP-43 immunoreactive neuronal cytoplasmic inclusion in the amygdala or the hippocampus of these aged animals (as well as in young and mature macaques used as negative controls). We concluded that LATE is probably a human-specific condition, such as many other proteinopathies, and does not participate in age-related memory impairment in non-human primates.
