The most frequent of these mutations, W515L and W515K, occur in exon 10 of<jats:italic>MPL<\/jats:italic>, which encodes the receptor for thrombopoietin. Another exon 10 mutation,<jats:italic>MPL<\/jats:italic>S505N, has been shown to be a founder mutation in several pedigrees with familial thrombocythaemia where it is associated with a high thrombotic risk, splenomegaly and progression to bone marrow fibrosis. Rare cases of sporadic, nonfamilial,<jats:italic>MPL<\/jats:italic>S505N MPN have been documented, but the presenting laboratory and clinical features have not been described in detail. The diagnosis and clinical course of a case of<jats:italic>MPL<\/jats:italic>S505N-positive MPN are presented with diagnostic features and treatment response resembling typical ET but with evidence of increasing bone marrow fibrosis. Further MPN cases possessing this genotype require reporting in order to ascertain whether any particular morphological or clinical features, if present, determine clinical course and aid the refinement of therapeutic options.<\/jats:p>","DOI":"10.1155\/2013\/729327","type":"journal-article","created":{"date-parts":[[2013,7,18]],"date-time":"2013-07-18T18:50:35Z","timestamp":1374173435000},"page":"1-4","source":"Crossref","is-referenced-by-count":4,"title":["Nonfamilial,<i>MPL<\/i>S505N-Mutated Essential Thrombocythaemia"],"prefix":"10.1155","volume":"2013","author":[{"given":"Ruth","family":"Morrell","sequence":"first","affiliation":[{"name":"Department of Haematology, Midland Regional Hospital, Tullamore, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen E.","family":"Langabeer","sequence":"additional","affiliation":[{"name":"Cancer Molecular Diagnostics, St. James\u2019s Hospital, Central Pathology Laboratory, Dublin 8, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liam","family":"Smyth","sequence":"additional","affiliation":[{"name":"Department of Haematology, Midland Regional Hospital, Tullamore, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meegahage","family":"Perera","sequence":"additional","affiliation":[{"name":"Department of Haematology, Midland Regional Hospital, Tullamore, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4105-9589","authenticated-orcid":true,"given":"Gerard","family":"Crotty","sequence":"additional","affiliation":[{"name":"Department of Haematology, Midland Regional Hospital, Tullamore, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2006-04-018879"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2008-01-131664"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1038\/leu.2008.137"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.13224"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1097\/PDM.0b013e3181ecd261"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2008-01-135897"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2003-10-3471"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.2009.005918"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.2009.007542"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2141.2010.08083.x"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1159\/000320171"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1007\/s12185-009-0413-3"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/j.bcmd.2011.04.004"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.3324\/haematol.2010.034793"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0023396"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.2353\/jmoldx.2008.080015"},{"issue":"1","key":"17","doi-asserted-by":"crossref","first-page":"25","DOI":"10.1111\/bjh.12075","volume":"160","year":"2013","journal-title":"British Journal of Haematology"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2008.20.3174"},{"issue":"2","key":"19","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1007\/s12308-011-0096-6","volume":"4","year":"2011","journal-title":"Journal of Hematopathology"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1182\/blood-2009-04-218842"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1038\/leu.2011.261"}],"container-title":["Case Reports in Hematology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crihem\/2013\/729327.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crihem\/2013\/729327.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crihem\/2013\/729327.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,21]],"date-time":"2017-06-21T12:28:10Z","timestamp":1498048090000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/crihem\/2013\/729327\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":21,"alternative-id":["729327","729327"],"URL":"https:\/\/doi.org\/10.1155\/2013\/729327","relation":{},"ISSN":["2090-6560","2090-6579"],"issn-type":[{"value":"2090-6560","type":"print"},{"value":"2090-6579","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013]]}}}
