A significantly higher rate of prenatal loss (22 per cent) as well as the presence of intrauterine growth retardation (IUGR) has been reported among pregnancies with CPM. To evaluate more precisely the effect of these aneuploid cell lines confined to the placenta on intrauterine fetal growth and fetal survival, we have studied 34 term placentae from pregnancies with CPM diagnosed on CVS and confirmed identical mosaicism in 17 of these placentae. There was a direct correlation between a high number of aneuploid cells present at CVS and a high likelihood of their detection in term placenta. Also, the proportion of aneuploid cells in the mosaic term placentae correlated with that observed in CVS specimens. Among 17 gestations with confirmed CPM at delivery, there were six cases of IUGR identified, five in liveborns and one associated with intrauterine death.<\/jats:p>","DOI":"10.1002\/pd.1970111002","type":"journal-article","created":{"date-parts":[[2007,3,4]],"date-time":"2007-03-04T04:15:41Z","timestamp":1172981741000},"page":"743-750","source":"Crossref","is-referenced-by-count":169,"title":["Confirmation of CVS mosaicism in term placentae and high frequency of intrauterine growth retardation association with confined placental mosaicism"],"prefix":"10.1002","volume":"11","author":[{"given":"D.
