The most common phenotype is a symmetrical length\u2010dependent sensory and motor neuropathy. Other phenotypes include non\u2010length\u2010dependent forms such as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) or a sensory neuronopathy or ganglionopathy. Asymmetric forms of neuropathy are mostly represented by mononeuritis multiplex and Lewis\u2010Sumner syndrome or focal CIDP. Unilateral weakness or sensory loss respecting the midline is mainly due to pathology in the central nervous system and is unusual in peripheral neuropathy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We evaluated the clinical and genetic features of three unrelated individuals with a peripheral neuropathy affecting one side of the body.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We describe three unrelated patients (two female and one male) with a slowly progressive peripheral neuropathy restricted to one side of the body. Each case is marked by onset in early childhood with the absence of a family history or a structural lesion of the central nervous system. Neurophysiology demonstrated an axonal type of neuropathy in two cases and conduction slowing supportive of a demyelinating neuropathy type in one. Genetic testing was performed in the three cases, specifically looking for variants in genes associated with Charcot\u2010Marie\u2010Tooth disease (CMT) but none were identified in DNA extracted from blood.<\/jats:p><\/jats:sec><jats:sec><jats:title>Interpretation<\/jats:title><jats:p>A unilateral, slowly progressive peripheral neuropathy is a rare phenomenon, and we propose the cause of this unusual phenotype to be due to a mosaic or chimeric form of Charcot\u2010Marie\u2010Tooth disease (CMT).<\/jats:p><\/jats:sec>","DOI":"10.1111\/jns.70033","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T06:48:15Z","timestamp":1748328495000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Case Series of Unilateral Peripheral Neuropathy"],"prefix":"10.1111","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-2480-3590","authenticated-orcid":false,"given":"Caroline","family":"Kramarz","sequence":"first","affiliation":[{"name":"Department of Neuromuscular Diseases Queen Square UCL Institute of Neurology and National Hospital for Neurology and Neurosurgery  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marion","family":"Masingue","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders, Nord\/Est\/Ile de France, Institut de Myologie CHU La Piti\u00e9\u2010Salp\u00eatri\u00e8re, APHP  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7oise","family":"Bouhour","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders PACARA Re, Department of ENMG and Neuromuscular Disease, Hopital Neurologique Hospices Civils de Lyon  Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christophe","family":"Vial","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders PACARA Re, Department of ENMG and Neuromuscular Disease, Hopital Neurologique Hospices Civils de Lyon  Lyon France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Latour","sequence":"additional","affiliation":[{"name":"Unit\u00e9 Fonctionnelle de Neurog\u00e9n\u00e9tique Mol\u00e9culaire CHU de Lyon\u2010HCL Groupement Est  Bron France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christophe","family":"Vandendries","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders, Nord\/Est\/Ile de France, Institut de Myologie CHU La Piti\u00e9\u2010Salp\u00eatri\u00e8re, APHP  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Maisonobe","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders, Nord\/Est\/Ile de France, Institut de Myologie CHU La Piti\u00e9\u2010Salp\u00eatri\u00e8re, APHP  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Coebergh","sequence":"additional","affiliation":[{"name":"St. George's University Hospitals National Health Service Foundation Trust  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julian","family":"Blake","sequence":"additional","affiliation":[{"name":"Department of Neuromuscular Diseases Queen Square UCL Institute of Neurology and National Hospital for Neurology and Neurosurgery  London UK"},{"name":"Department of Clinical Neurophysiology Norfolk and Norwich University Hospital  Norwich UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mary M.","family":"Reilly","sequence":"additional","affiliation":[{"name":"Department of Neuromuscular Diseases Queen Square UCL Institute of Neurology and National Hospital for Neurology and Neurosurgery  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanya","family":"Stojkovic","sequence":"additional","affiliation":[{"name":"Reference Center for Neuromuscular Disorders, Nord\/Est\/Ile de France, Institut de Myologie CHU La Piti\u00e9\u2010Salp\u00eatri\u00e8re, APHP  Paris France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4648-2896","authenticated-orcid":false,"given":"Alexander M.","family":"Rossor","sequence":"additional","affiliation":[{"name":"Department of Neuromuscular Diseases Queen Square UCL Institute of Neurology and National Hospital for Neurology and Neurosurgery  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,26]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp-2014-309096"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/ene.15937"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1001\/archneurol.2010.58"},{"key":"e_1_2_8_5_1","unstructured":"M.Masingue B.Rucheton C.Bris N.
