Feal deaths were 3,285 for twins, 141 for triplets, 17 for quadruplets, and 5 for quintuplets, among which the numbers of birth defects were 78, 3, 0, and 0, respectively. Concordant twin pairs with the same category of birth defect were 20 among 56 pairs (0.36). As for the remaining 36 pairs, 2 pairs had different category of birth defects, 27 pairs had liveborn cotwins, and 7 pairs were both fetal deaths among which a twin had birth defect. The second-born twins had birth defects more frequently than the first-born twins among fetal deaths (28 vs 6).<\/jats:p>","DOI":"10.1017\/s0001566000005262","type":"journal-article","created":{"date-parts":[[2016,7,27]],"date-time":"2016-07-27T10:00:58Z","timestamp":1469613658000},"page":"345-350","source":"Crossref","is-referenced-by-count":2,"title":["Fetal Deaths with Birth Defects Among Japanese Multiples, 1974"],"prefix":"10.1017","volume":"39","author":[{"given":"Y.","family":"Imaizumi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Asaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"Inouye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,8,1]]},"reference":[{"key":"S0001566000005262_ref014","first-page":"69","article-title":"Congenital malformation in twins","volume":"32","author":"Layde","year":"1980","journal-title":"Am J Hum Genet"},{"key":"S0001566000005262_ref006","doi-asserted-by":"publisher","DOI":"10.1007\/BF01908194"},{"key":"S0001566000005262_ref002","doi-asserted-by":"publisher","DOI":"10.1007\/BF01873605"},{"key":"S0001566000005262_ref015","first-page":"151","article-title":"Congenital malformations: The contribution of twin studies","volume":"6A","author":"Myrianthopoulos","year":"1978","journal-title":"Birth Defects Orig Art Ser 14"},{"key":"S0001566000005262_ref012","volume-title":"Health and Welfare Statistics and Information Department, Ministry of Health and Welfare, Tokyo","year":"1976"},{"key":"S0001566000005262_ref001","volume-title":"In: Gene Environmental Interaction in Common Diseases","author":"Ando","year":"1977"},{"key":"S0001566000005262_ref009","doi-asserted-by":"publisher","DOI":"10.1111\/j.1741-4520.1990.tb00496.x"},{"key":"S0001566000005262_ref013","volume-title":"Health and Welfare Statistics and Information Department, Ministry of Health and Welfare, Tokyo","year":"1977"},{"key":"S0001566000005262_ref004","first-page":"336","article-title":"The genetics of cleft lip and cleft palate","volume":"22","author":"Fraser","year":"1970","journal-title":"Am J Hum Genet"},{"key":"S0001566000005262_ref010","doi-asserted-by":"publisher","DOI":"10.1017\/S0001566000009144"},{"key":"S0001566000005262_ref005","first-page":"662","article-title":"Congenital malformations in twins","volume":"22","author":"Hay","year":"1970","journal-title":"Am J Hum Genet"},{"key":"S0001566000005262_ref011","first-page":"33","article-title":"Incidence of anencephaly in Japan: Maternal age, birth order, seasonal variation and social class effects","volume":"139","author":"Imaizumi","year":"1976","journal-title":"The Journal of Population Problems"},{"key":"S0001566000005262_ref008","doi-asserted-by":"publisher","DOI":"10.1002\/tera.1420400203"},{"key":"S0001566000005262_ref007","first-page":"279","article-title":"Congenital hydrocephalus in Japan 1969-1982: Secular trends, geographical and social class variations","volume":"28","author":"Imaizumi","year":"1988","journal-title":"Congenital Anomalies"},{"key":"S0001566000005262_ref003","volume-title":"Epidemiology of Anencephalus and Spina Bifida","author":"Elwood","year":"1980"}],"container-title":["Acta geneticae medicae et gemellologiae: twin research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0001566000005262","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,18]],"date-time":"2019-05-18T20:49:19Z","timestamp":1558212559000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0001566000005262\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1990,7]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1990,7]]}},"alternative-id":["S0001566000005262"],"URL":"https:\/\/doi.org\/10.1017\/s0001566000005262","relation":{},"ISSN":["0001-5660","2059-6324"],"issn-type":[{"value":"0001-5660","type":"print"},{"value":"2059-6324","type":"electronic"}],"subject":[],"published":{"date-parts":[[1990,7]]}}}
