The CMT disease is an untreatable disease characterized by progressive muscle weakness, atrophy, and sensory impairment, primarily affecting the peripheral nerves.In our institution, we collected blood samples from patients with the CMT disease, nationwide, and performed comprehensive genetic testing to elucidate its underlying causes.Using next‐generation sequencing (NGS), we successfully discovered two novel causative genes of the CMT disease, membrane metalloendopeptidase (MME), and cytochrome c oxidase assembly factor 7, via whole exome analysis of previously unidentified cases. These findings, combined with the comprehensive analysis enabled by NGS, have significantly improved the diagnostic rate of this disease.Notably, the MME gene has been reported as the most frequent causative gene for autosomal recessive CMT disease, attracting global attention and subsequent research efforts. Accurate genetic diagnosis for each patient serves as a crucial first step toward understanding hereditary diseases. The identification of new causes of the CMT disease can assist in elucidating the molecular mechanisms involved completely, further contributing to the development of effective treatment approaches, including gene therapies.","PeriodicalId":19154,"journal":{"name":"Neurology and Clinical Neuroscience","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46547004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He was admitted to the hospital due to prolonged fever with liver enzyme elevations, diagnosed as primary Epstein–Barr virus infection. During conservative management, his fever and liver dysfunction persisted, with elevated serum inflammatory marker levels, and the precursor state of Epstein–Barr virus‐associated hemophagocytic lymphohistiocytosis was suspected. Although his symptoms and liver dysfunction trended toward amelioration after short‐term prednisolone, left‐sided facial palsy developed acutely. Facial palsy was considered Epstein–Barr virus infection‐related, and he recovered within 1 month following additional steroid therapy. Given the presence of the precursor condition of hemophagocytic lymphohistiocytosis just prior to facial palsy, hypercytokinemia was considered a possible pathogenic mechanism for the facial palsy. In patients with Epstein–Barr virus infection, facial palsy may occur independently of the recovery of other symptoms, and cytokine disturbance may affect its development.","PeriodicalId":19154,"journal":{"name":"Neurology and Clinical Neuroscience","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47852011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The committee for fostering board‐certified neurologists in the Japanese Society of Neurology (JSN) has hosted an educational activity for residents before the board examination, “The seminar for fostering board‐certified neurologists” since 2004. In particular, the autumn seminar has been characterized by small group hands‐on of neurological examinations and the evaluations of higher brain function. Besides this, hands‐on seminar of neurological examinations by regional branches has been promoted by the JSN. In the Kanto Ko‐shin‐etsu branch, “The first hands‐on seminar of neurological examinations” started in 2023 after a 3‐year‐suspension due to COVID‐19. The most important educational activities in neuromuscular electrodiagnosis (EDx) is the “Neuromuscular diagnostics seminar” hosted since 2004 by the Japanese Society of Clinical Neurophysiology (JSCN). The majority of tutors and participants are neurologists. This seminar is also characterized by small‐group, hands‐on workshops. We have also run the overseas seminar, “Tokyo Super EMG hands‐on,” since 2013. These have undoubtedly contributed to enhancing the level of neuromuscular electrodiagnosis not only in Japan but also in other Asian countries. I have conducted studies on neurological symptomatology and neuromuscular electrodiagnosis, which are directly linked to enhancing clinical practice of neurologists through educational activities such as review articles or lectures. Due to the fact that symptomatology is crucial in neurological expertise, neurology is a basic specialty around the world except in Japan. In 2018, the JSN decided to aim to make neurology a basic specialty and continues to make efforts to attain this goal.","PeriodicalId":19154,"journal":{"name":"Neurology and Clinical Neuroscience","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2023-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46332575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
