Our role, as physicians, is to determine whether the neuropathy is directly related to the gammopathy or whether the co\u2010occurrence of these two disorders is purely coincidental. The evaluating physician needs to be familiar with the different types of neuropathies associated with monoclonal gammopathies, their clinical and electrodiagnostic characteristics, and their appropriate diagnostic evaluation and management. Testing for monoclonal protein disorders includes serum protein electrophoresis (SPEP) and immunofixation of blood, and in some cases of urine, as well as measurement of free light chains and quantitative immunoglobulins. Specific antibody testing is directed by paraprotein type and neuropathy phenotype. Patients with abnormal free light chains in association with sensory and autonomic neuropathy should be evaluated for AL amyloidosis. When a lambda monoclonal protein is identified together with a clinical phenotype of chronic inflammatory demyelinating neuropathy (CIDP), a diagnosis of polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder, skin changes (POEMS) syndrome should be considered. Patients with IgM paraprotein associated neuropathy should be assessed for distal acquired demyelinating sensorimotor (DADS) neuropathy, with or without anti myelin associated glycoprotein (MAG) antibody or CANOMAD syndrome. In many cases, a monoclonal gammopathy of uncertain significance (MGUS) is incidental and unrelated to the neuropathy. Collaboration with oncology is critical in evaluating patients with monoclonal proteins to assess for underlying plasma cell neoplasms or B cell lymphomas.<\/jats:p>","DOI":"10.1002\/mus.28164","type":"journal-article","created":{"date-parts":[[2024,5,31]],"date-time":"2024-05-31T00:59:41Z","timestamp":1717117181000},"page":"173-179","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Paraproteinemic neuropathies"],"prefix":"10.1002","volume":"70","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0611-1302","authenticated-orcid":false,"given":"Rebecca","family":"Traub","sequence":"first","affiliation":[{"name":"Department of Neurology University of North Carolina  Chapel Hill North Carolina USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taha","family":"Qarni","sequence":"additional","affiliation":[{"name":"Department of Neurology University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam D.","family":"Cohen","sequence":"additional","affiliation":[{"name":"Division of Hematology\/Oncology, Department of Medicine University of Pennsylvania  Philadelphia Pennsylvania USA"},{"name":"Amyloidosis Program University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3868-2994","authenticated-orcid":false,"given":"Chafic","family":"Karam","sequence":"additional","affiliation":[{"name":"Department of Neurology University of Pennsylvania  Philadelphia Pennsylvania USA"},{"name":"Amyloidosis Program University of Pennsylvania  Philadelphia Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,5,30]]},"reference":[{"key":"e_1_2_15_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470\u20102045(20)30756\u20107"},{"key":"e_1_2_15_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/leu.2008.307"},{"key":"e_1_2_15_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600\u20100404.1992.tb06033.x"},{"key":"e_1_2_15_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410300111"},{"key":"e_1_2_15_6_1","doi-asserted-by":"publisher","DOI":"10.4065\/84.8.685"},{"key":"e_1_2_15_7_1","article-title":"Primary systemic amyloidosis: clinical and laboratory features in 474 cases","volume":"32","author":"Kyle RA","year":"1995","journal-title":"Semin Hematol"},{"key":"e_1_2_15_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468\u20101331.2010.03215.x"},{"key":"e_1_2_15_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002\u20109343(98)00037\u20100"},{"key":"e_1_2_15_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mayocp.2016.06.027"},{"key":"e_1_2_15_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2018.07.092"},{"key":"e_1_2_15_12_1","doi-asserted-by":"publisher","DOI":"10.1373\/clinchem.2004.046870"},{"key":"e_1_2_15_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022\u2010510X(93)90025\u2010T"},{"key":"e_1_2_15_14_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.116.021612"},{"key":"e_1_2_15_15_1","doi-asserted-by":"publisher","DOI":"10.1309\/PFUGHBX0TY20E08U"},{"key":"e_1_2_15_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajh.25495"},{"key":"e_1_2_15_17_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp\u20102011\u2010301706"},{"key":"e_1_2_15_18_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp\u20102011\u2010301472"},{"key":"e_1_2_15_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00277\u2010014\u20102019\u2010y"},{"key":"e_1_2_15_20_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330\u2010014\u20103428\u2010y"},{"key":"e_1_2_15_21_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood\u20102010\u201011\u2010316935"},{"key":"e_1_2_15_22_1","doi-asserted-by":"publisher","DOI":"10.1182\/blood\u20102011\u201006\u2010362392"},{"key":"e_1_2_15_23_1","article-title":"Peripheral neuropathy and anti\u2010MAG antibodies","volume":"3","author":"Latov N","year":"1987","journal-title":"Crit Rev Neurobiol"},{"key":"e_1_2_15_24_1","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp\u20102017\u2010316715"},{"key":"e_1_2_15_25_1","doi-asserted-by":"publisher","DOI":"10.1002\/mus.20678"},{"key":"e_1_2_15_26_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jneuroim.2020.577288"},{"key":"e_1_2_15_27_1","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD002827.pub4"},{"key":"e_1_2_15_28_1","doi-asserted-by":"publisher","DOI":"10.1002\/ana.21577"},{"key":"e_1_2_15_29_1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0b013e318296e92b"},{"key":"e_1_2_15_30_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2017.04.015"},{"key":"e_1_2_15_31_1","doi-asserted-by":"publisher","DOI":"10.1212\/NXI.0000000000001109"},{"key":"e_1_2_15_32_1","doi-asserted-by":"publisher","DOI":"10.1182\/BLOOD.2020007092"}],"container-title":["Muscle &amp;
