We selected 50 infants with IUGR (&lt;\u22122.0 SD) from 3,257 deliveries in a regional medical center during the past 10\u2010year period, and carried out cytogenetic and molecular analyses in their placenta and cord blood. Of the 50 infants, 8 had CPM (CPM group) and were composed of five single (CPM2, 7, 13, 22, and 22), one double (CPM7\/13), and one quadruple trisomy (CPM2\/7\/15\/20), and one partial monosomy [del(2)(p16)]. The origin of an extra chromosome of trisomy was maternal in six cases of CPM, paternal in one, and undetermined in one. Uniparental disomy in disomic cell lines was ruled out in all these mosaics. We also compared clinical parameters for perinatal outcome between CPM group and infants without evidence of CPM (non\u2010CPM group), such as maternal and gestational age, birth weight, <jats:italic>Apgar<\/jats:italic> score, cord blood pH, gender, and uterine artery patterns by Doppler ultrasonography, as well as weight, height, and developmental quotient (DQ) by Denver Developmental Screening Test at age 12 months. Phenotypic abnormalities were noted in two infants with CPM and three infants of non\u2010CPM group: One with CPM22 had ASD and hypospadias, one with CPM7\/13 had Russell\u2013Silver syndrome (RSS), and one without CPM had polydactyly, and two without CPM had RSS. All but one infant with CPM are alive at age 12 months. Among the clinical parameters, the detection rate of a notch waveform pattern of the uterine artery was significantly higher in the CPM group (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). However, no significant difference was noted in perinatal outcome of pregnancy and in DQ at age 12 months between the two groups. Interestingly, short stature (&lt;\u22122 SD) at age 12 months was more frequently seen in CPM group (7\/8 infants with CPM vs. 8\/15 infants without CPM), although no statistically significant difference was obtained. The information obtained will be useful for perinatal care and genetic counseling for infants with IUGR and CPM. \u00a9 2006 Wiley\u2010Liss,
