X-linked Charcot Marie Tooth disease type 1 (CMTX1) is a clinically heterogenous X-linked hereditary neuropathy caused by mutation of the gene encoding gap junction beta 1 protein (GJB1). Typical clinical manifestations of CMTX1 are progressive weakness or sensory disturbance due to peripheral neuropathy. However, there have been some CMTX1 cases with accompanying central nervous system (CNS) manifestations. We report the case of a genetically confirmed CMTX1 patient who presented recurrent transient CNS symptoms without any symptom or sign of peripheral nervous system involvement.

AbstractCharcot-Marie-Tooth disease type 1 A (CMT1A) lacks an effective treatment. We provide a therapy for CMT1A, based on siRNA conjugated to squalene nanoparticles (siRNA PMP22-SQ NPs). Their administration resulted in normalization of Pmp22 protein levels, restored locomotor activity and electrophysiological parameters in two transgenic CMT1A mouse models with different severity of the disease. Pathological studies demonstrated the regeneration of myelinated axons and myelin compaction, one major step in restoring function of myelin sheaths. The normalization of sciatic nerve Krox20, Sox10 and neurofilament levels reflected the regeneration of both myelin and axons. Importantly, the positive effects of siRNA PMP22-SQ NPs lasted for three weeks, and their renewed administration resulted in full functional recovery. Beyond CMT1A, our findings can be considered as a potent therapeutic strategy for inherited peripheral neuropathies. They provide the proof of concept for a new precision medicine based on the normalization of disease gene expression by siRNA.

ABSTRACT Background: Charcot-Marie-Tooth disease type 1A (CMT1A) is the most common form of hereditary neuropathy. Objective: To investigate the prevalence and characteristics of pain in patients with CMT1A. Methods: Nineteen patients with a diagnosis of CMT1A were evaluated between September 2018 and October 2019, and other causes of neuropathy were ruled out. The following tools were used for the pain assessment: neurological assessment, LANSS, DN4, clinical evaluation, VAS, CMTNS2 and SF-36. Statistical analysis was performed using prevalence analysis, t test, chi-square test and Spearman's rho. Results: The prevalence of pain was 84.2% in the sample of this study, with moderate intensity and nociceptive characteristics according to the LANSS scale (75%) and clinical evaluation (50%), but differing from DN4, which found neuropathic pain in the majority of the patients (56.2%). Mixed pain was also observed in 43.7% of the patients, according to clinical criteria. There was a statistically significant correlation between pain intensity and SF-36, thus demonstrating that the lower the pain was, the lower the impairment was, in all domains. Conclusion: Pain is a prevalent and important symptom in CMT1A, with moderate intensity and nociceptive characteristics according to two tools, but neuropathic pain is also present, and there may even be a mixed pattern of pain. The correlation of the pain with SF-36 suggests that pain relief could provide improvements to the quality of life of these individuals.
