Our patient belongs to a non-endemic region and due to his lack of support network a possible familial component is unknown. His case represents a diagnostic challenge given the wide heterogeneity of clinical manifestations associated with the disease, with other possible diagnoses of polyneuropathy being reasonably excluded according to prevalence and frequency. The particularly unusual genotype-phenotype association distinguishes this case from the classic description of transthyretin amyloidosis secondary to p.Val142Ile.<\/jats:p>","DOI":"10.1177\/11795476241253106","type":"journal-article","created":{"date-parts":[[2024,5,15]],"date-time":"2024-05-15T08:09:51Z","timestamp":1715760591000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Polyneuropathy as an initial manifestation of Hereditary Transtyretin Amyloidosis (ATTRV) in a young patient: Case report of a diagnostic challenge"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0031-868X","authenticated-orcid":false,"given":"Julieth Vivian","family":"Sarmiento Palma","sequence":"first","affiliation":[{"name":"Pontificia Universidad Javeriana, School of Medicine, Bogot\u00e1, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Santiago","family":"Sambracos Parrado","sequence":"additional","affiliation":[{"name":"Pontificia Universidad Javeriana, School of Medicine, Bogot\u00e1, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Camila","family":"Echeverria","sequence":"additional","affiliation":[{"name":"Pontificia Universidad Javeriana, School of Medicine, Bogot\u00e1, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paula","family":"Ruiz Talero","sequence":"additional","affiliation":[{"name":"Pontificia Universidad Javeriana, School of Medicine, Bogot\u00e1, Colombia"},{"name":"Department of Internal Medicine, Hospital Universitario San Ignacio, Bogot\u00e1, Colombia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,5,15]]},"reference":[{"key":"bibr1-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1186\/s13023-019-1000-1"},{"key":"bibr2-11795476241253106","first-page":"1036","volume":"86","author":"Sekjima Y.","year":"2015","journal-title":"J Neurol Neurocirug\u00eda Psiquiatr\u00eda"},{"key":"bibr3-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.59.11.1771"},{"key":"bibr4-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1111\/jns.12451"},{"key":"bibr5-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1007\/s10286-019-00624-w"},{"key":"bibr6-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1186\/s13256-022-03437-0"},{"key":"bibr7-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1007\/s10072-016-2767-7"},{"key":"bibr8-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1097\/CND.0000000000000238"},{"key":"bibr9-11795476241253106","first-page":"499","volume":"15","author":"Di Stefano V","year":"2022","journal-title":"Pharmgenomics Pers Med"},{"key":"bibr10-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1080\/13506120500107162"},{"key":"bibr11-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCGEN.121.003356"},{"key":"bibr12-11795476241253106","volume":"31","author":"Di Stefano V","year":"2024","journal-title":"Eur J Neurol"},{"key":"bibr13-11795476241253106","doi-asserted-by":"publisher","DOI":"10.2147\/TCRM.S219979"},{"key":"bibr14-11795476241253106","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp-2016-315262"}],"container-title":["Clinical Medicine Insights: Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/11795476241253106","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/11795476241253106","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/11795476241253106","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T09:14:28Z","timestamp":1777454068000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/11795476241253106"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1]]},"references-count":14,"alternative-id":["10.1177\/11795476241253106"],"URL":"https:\/\/doi.org\/10.1177\/11795476241253106","relation":{},"ISSN":["1179-5476","1179-5476"],"issn-type":[{"value":"1179-5476","type":"print"},{"value":"1179-5476","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,1]]},"article-number":"11795476241253106"}}
