In a pregnancy that was monitored due to increased risk for Down syndrome in the triple test, a normal karyotype was found in amniocentesis. Follow-up by serial ultrasound examinations revealed intrauterine growth retardation (IUGR) at 20 weeks of gestation. The parents decided to terminate the preg

โฆ Synopsis
This report describes a case of apparent confined placental mosaicism for trisomy 8 in a pregnancy which produced a male infant with intra-uterine growth retardation. Postnatal cytogenetic and molecular studies were consistent with biparental disomy 8. Postnatally, the infant experienced a period of rapid catch-up growth and exhibited no clinical features of trisomy 8 mosaicism. His development was age appropriate. 1998 John Wiley & Sons, Ltd.

Karyotypically normal fetuses with completely trisomic or mosaic placentae may be at increased risk for intrauterine growth restriction (IUGR). Molecular and cytogenetic analyses on nine pregnancies with confined placental mosaicism (CPM) for trisomy 2 were performed at two collaborating centres. Se
