Myopathy was the initial manifestation in all ATTRwt patients and followed peripheral neuropathy (4 patients) or cardiomyopathy (1 patient) in ATTRv patients. One ATTRv patient developed myopathy after liver transplant. Peripheral neuropathy and cardiac amyloidosis occurred in seven and six patients, respectively. Muscle biopsy showed interstitial amyloid deposition in all patients, rare necrotic\/regenerating fibers in six, and vacuoles in four.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>Myopathy can be the initial manifestation of ATTRwt amyloidosis and can precede the peripheral neuropathy or occur after liver transplant in ATTRv amyloidosis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/mus.26723","type":"journal-article","created":{"date-parts":[[2019,10,6]],"date-time":"2019-10-06T04:18:50Z","timestamp":1570335530000},"page":"95-100","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Transthyretin amyloidosis: Putting myopathy on the map"],"prefix":"10.1002","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9890-6657","authenticated-orcid":false,"given":"Marcus V.","family":"Pinto","sequence":"first","affiliation":[{"name":"Department of Neurology Mayo Clinic  Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margherita","family":"Milone","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic  Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle L.","family":"Mauermann","sequence":"additional","affiliation":[{"name":"Department of Neurology Mayo Clinic  Rochester Minnesota"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.
