At birth, twin A presented as a phenotypically normal female with 46,XY karyotype, and 46,XY gonadal dysgenesis was suspected. Twin B was a normal male. &lt;i&gt;Results:&lt;\/i&gt; In our department, further examinations of twin A included undetectable testosterone and inhibin-B and elevated FSH. Ultrasound suspected an infantile uterus, and sequencing of the SRY gene was normal. After gonadectomy, a 46,XX karyotype was demonstrated in both normal infantile ovaries and in the fibroblasts from a skin biopsy. Analysis of X-linked markers in DNA from blood lymphocytes in both twins was identical, consistent with 46,XY karyotypes. &lt;i&gt;Conclusion:&lt;\/i&gt; Twin A is a 46,XX female with a chimeric 46,XY blood cell line due to intrauterine transfusion from her twin brother.<\/jats:p>","DOI":"10.1159\/000072527","type":"journal-article","created":{"date-parts":[[2003,8,22]],"date-time":"2003-08-22T08:19:50Z","timestamp":1061540390000},"page":"148-151","source":"Crossref","is-referenced-by-count":10,"title":["Erroneous Genetic Sex Determination of a Newborn Twin Girl due to Chimerism Caused by Foetal Blood Transfusion"],"prefix":"10.1159","volume":"60","author":[{"given":"T.H.","family":"Johannsen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Lundsteen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Visfeldt","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Schwartz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.L.","family":"Petersen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.G.","family":"Byskov","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"M\u00fcller","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2003,8,29]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19960122)61:3<264::AID-AJMG11>3.0.CO;2-R"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/0165-4608(87)90180-4"}],"container-title":["Hormone Research in Paediatrics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/72527","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/72527","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:41:05Z","timestamp":1745466065000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000072527"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003]]},"references-count":2,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2003,7,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000072527","archive":["Portico"],"relation":{},"ISSN":["1663-2818","1663-2826"],"issn-type":[{"type":"print","value":"1663-2818"},{"type":"electronic","value":"1663-2826"}],"subject":[],"published":{"date-parts":[[2003]]}}}
