The parental origin of the extra chromosome 21 was determined by cytogenetic methods. All individuals were caucasians and there was no history of consanguinity. No excessive HLA sharing was present in D.S. parents. The mothers of D.S. shared no more HLA antigens with their D.S. children than the control mothers with their normal children (14% vs. 18%). Thirteen of the fifty pairs (26%) (parent in whom the nondisjunction occurred and D.S. child) shared three HLA antigens at the A and\/or B locus. This was not significantly higher than the proportion in the control group (12\/50 or 24%). These data suggest that it is not the sharing of HLA\u2010A and HLA\u2010B antigens between the parents or between the parent who was the origin of the nondisjunction and the D.S. child that is related either to the occurrence of trisomy 21 zygotes or to prenatal survival of affected embryos and fetuses.<\/jats:p>","DOI":"10.1002\/gepi.1370050405","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T21:48:31Z","timestamp":1118526511000},"page":"235-240","source":"Crossref","is-referenced-by-count":3,"title":["HLA and down syndrome (DS): Parents at the origin of the nondisjunction share no more HLA\u2010A and \u2010B antigens with their DS child than controls"],"prefix":"10.1002","volume":"5","author":[{"given":"C.","family":"Stoll","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.","family":"Alembik","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Armbruster","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MM","family":"Tongio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"Mayer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.
