We report a liveborn infant with severe intrauterine growth retardation and renal failure, delivered following detection of non-mosaic trisomy 2 by chorionic villus biopsy in the first trimester. Detailed analysis post-delivery indicated apparent complete trisomy 2 of the chorionic tissues, with a c

We present a case of maternal uniparental heterodisomy for chromosome 2 (UPD 2) detected after trisomy 2 mosaicism was found on placental biopsy. This case presented prenatally with severe intrauterine growth restriction (IUGR) and oligohydramnios. The diploid newborn had hypospadias and features co
We report on a case of generalized mosaicism for trisomy 22. At chorionic villus sampling (CVS) in the 37th week of pregnancy, a 47,XX,+22 karyotype was detected in all cells. The indication for CVS was severe unexplained symmetrical intrauterine growth retardation (IUGR) and a ventricular septal de
We report on a maternal uniparental disomy of chromosome 22 in a patient with severe intra-uterine growth retardation. Karyotyping of a placental tissue revealed non-mosaic trisomy 22, whereas lymphocyte chromosomes from the newborn were normal 46,XY. Microsatellite analysis using DNA extracted from
