Consequently, the population is highly uniform and has limited HLA diversity relative to people from other countries. However, Japan has three ethnolinguistic groups, and HLA distributions differ depending on geographic region. To collect an HLA\u2010rich variety of bone marrow bank donor registrants, it is essential to know the precise distribution of HLA in Japan. We analyzed HLA alleles and haplotypes based on HLA information of 177\u2009041 bone marrow donor registrants. Registrants were grouped depending on the prefecture and region (a group of prefectures) as commonly used in Japan. The prefectures did not show the same distributions, but the tendency was similar for each region. We found that Okinawa Prefecture and the mainland can be clearly divided as haplotypes: [<jats:italic>A*24:02\u2010C<\/jats:italic>*<jats:italic>01:02\u2010B*54:01\u2010DRB1<\/jats:italic>*04:05] and [<jats:italic>A*24:02\u2010C*01:02\u2010B*59:01\u2010DRB1*04:05<\/jats:italic>] were typically found in Okinawa (<jats:italic>P<\/jats:italic> = .02, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001). Moreover, these types were found almost exclusively in Japan and Korea. Donor registration centers of the Japan Marrow Donor Program are currently located in all prefectures. It is essential to deploy registration centers to collect registrants with a large variety of HLA types covering all of Japan.<\/jats:p>","DOI":"10.1111\/tan.13881","type":"journal-article","created":{"date-parts":[[2020,3,28]],"date-time":"2020-03-28T06:01:32Z","timestamp":1585375292000},"page":"24-42","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Implications of <scp>HLA<\/scp> diversity among regions for bone marrow donor searches in Japan"],"prefix":"10.1111","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2555-6705","authenticated-orcid":false,"given":"Shiho","family":"Hashimoto","sequence":"first","affiliation":[{"name":"Department of Laboratory Molecular Genetics of Hematology Tokyo Medical and Dental University  Tokyo Japan"},{"name":"Blood Service Headquarters Japanese Red Cross Society  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumiaki","family":"Nakajima","sequence":"additional","affiliation":[{"name":"Blood Service Headquarters Japanese Red Cross Society  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadashi","family":"Imanishi","sequence":"additional","affiliation":[{"name":"Graduate School of Medicine Tokai University School of Medicine  Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yosuke","family":"Kawai","sequence":"additional","affiliation":[{"name":"Genome Medical Science Project National Center for Global Health and Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazue","family":"Kato","sequence":"additional","affiliation":[{"name":"Blood Service Headquarters Japanese Red Cross Society  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takafumi","family":"Kimura","sequence":"additional","affiliation":[{"name":"Japanese Red Cross Society Kinki Block Blood Center  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeki","family":"Miyata","sequence":"additional","affiliation":[{"name":"Blood Service Headquarters Japanese Red Cross Society  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minoko","family":"Takanashi","sequence":"additional","affiliation":[{"name":"Blood Service Headquarters Japanese Red Cross Society  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miwako","family":"Nishio","sequence":"additional","affiliation":[{"name":"Department of Laboratory Molecular Genetics of Hematology Tokyo Medical and Dental University  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsushi","family":"Tokunaga","sequence":"additional","affiliation":[{"name":"Genome Medical Science Project National Center for Global Health and Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Satake","sequence":"additional","affiliation":[{"name":"Blood Service Headquarters Japanese Red Cross Society  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,5,12]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41409-017-0084-2"},{"key":"e_1_2_8_3_1","volume-title":"International cooperation of Unrelated peripheral blood stem cell transplantation","author":"Japan Marrow Donor Program","year":"2019"},{"key":"e_1_2_8_4_1","volume-title":"WMDA publications \u201cWMDA activities report 2017\u201d","author":"World Marrow Donor Association","year":"2019"},{"key":"e_1_2_8_5_1","unstructured":"Japanese Red Cross Society. \u201cStatistical data.\u201d Service of Hematopoietic stem cell transplant informationhttp:\/\/www.bmdc.jrc.or.jp\/generalpublic\/statistics.html.
