The abnormalities of the plasma and platelet vWf have not been previously described. In particular, the patient's plasma and platelet vWf lacked the intermediate and largest vWf multimers and the slowest migrating minor band (band 1) of the triplet was markedly diminished compared to the major band (band 2) and the fastest migrating band of the triplet (band 3). A similar multimeric structure was seen in the platelet vWf. Collection of the patient's blood in protease inhibitors prior to the analysis of the platelet and plasma vWf structure revealed that the plasma vWf multimeric structure did not change, while the patient's platelet vWf showed a marked change with the appearance of the intermediate and large multimers and almost total disappearance of the abnormal multimeric structure. Direct comparison of this patient's plasma with previously reported cases of type IIA, IIC, and IID revealed marked differences in their multimeric organization compared to our patient. Employing the presently accepted convention, we have designated this variant type of vWd type IIG.<\/jats:p>","DOI":"10.1002\/ajh.2830240305","type":"journal-article","created":{"date-parts":[[2007,2,21]],"date-time":"2007-02-21T10:38:25Z","timestamp":1172054305000},"page":"259-266","source":"Crossref","is-referenced-by-count":23,"title":["A variant of type II von willebrand disease with an abnormal triplet structure and discordant effects of protease inhibitors on plasma and platelet von willebrand factor structure"],"prefix":"10.1002","volume":"24","author":[{"given":"Harvey R.","family":"Gralnick","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sybil B.","family":"Williams","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurie P.","family":"McCkeown","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pascal","family":"Maisonneuve","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine","family":"Jenneau","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yvette","family":"Sultan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,7,11]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI109795"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI110700"},{"key":"e_1_2_1_4_2","doi-asserted-by":"crossref","first-page":"1000","DOI":"10.1182\/blood.V62.5.1000.1000","article-title":"A variant of von Willebrand's disease characterized by recessive inheritance and missing triplet structure of von Willebrand factor multimers","volume":"62","author":"Mannucci PM","year":"1983","journal-title":"Blood"},{"key":"e_1_2_1_5_2","doi-asserted-by":"crossref","first-page":"1369","DOI":"10.1182\/blood.V63.6.1369.1369","article-title":"A new variant of dominant type II von Willebrand's disease with aberrant multimeric pattern of factor VIII\u2010related antigen (type IId)","volume":"63","author":"Kinoshita S","year":"1984","journal-title":"Blood"},{"key":"e_1_2_1_6_2","first-page":"501A","article-title":"High resolution NaDodSO4\u2010agarose electrophoresis identifies new molecular abnormalities in von Willebrand's disease","volume":"32","author":"Zimmerman TS","year":"1984","journal-title":"Clin Res"},{"key":"e_1_2_1_7_2","first-page":"189","article-title":"A new variant of type II von Willebrand's disease with aberrant multimeric structure of von Willebrand factor","volume":"54","author":"Mannucci PM","year":"1985","journal-title":"Thromb Haemost"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1172\/JCI108160"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.82.17.5968"},{"key":"e_1_2_1_10_2","doi-asserted-by":"crossref","first-page":"387","DOI":"10.1182\/blood.V58.2.387.387","article-title":"Effect of the multimeric structure of the factor VIII\/von Willebrand factor protein on binding to platelets","volume":"58","author":"Gralnick HR","year":"1981","journal-title":"Blood"},{"key":"e_1_2_1_11_2","first-page":"790","article-title":"Factor VIII\u2010related protein circulates in normal human plasma as high molecular weight multimers","volume":"60","author":"Hoyer LW","year":"1982","journal-title":"Blood"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0049-3848(75)90086-9"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/0049-3848(85)90205-1"}],"container-title":["American Journal of Hematology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajh.2830240305","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajh.2830240305","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,22]],"date-time":"2023-10-22T06:52:40Z","timestamp":1697957560000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajh.2830240305"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1987,3]]},"references-count":12,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1987,3]]}},"alternative-id":["10.1002\/ajh.2830240305"],"URL":"https:\/\/doi.org\/10.1002\/ajh.2830240305","archive":["Portico"],"relation":{},"ISSN":["0361-8609","1096-8652"],"issn-type":[{"value":"0361-8609","type":"print"},{"value":"1096-8652","type":"electronic"}],"subject":[],"published":{"date-parts":[[1987,3]]}}}
