PG - 566-71 LID - S1028-4559(14)00190-9 [pii] LID - 10.1016/j.tjog.2014.09.004 [doi] AB - OBJECTIVE: This study aims to present molecular cytogenetic characterization of Pallister-Killian syndrome (PKS). MATERIALS AND METHODS: A 37-year-old woman underwent amniocentesis at 18 weeks of gestation. Amniocentesis revealed a karyotype of 47,XY,+i(12)(p10)[6]/48,XY,+i(12)(p10)x2[1]/46,XY[6]. Repeated amniocentesis was performed at 20 weeks of gestation. Array comparative genomic hybridization (aCGH) was performed using uncultured amniocytes, cord blood, and skin. Quantitative fluorescent polymerase chain reaction (QF-PCR) was performed using uncultured amniocytes and parental bloods. Interphase fluorescence in situ hybridization (FISH) analysis was performed using uncultured amniocytes and cultured stimulated cord blood lymphocytes. Conventional cytogenetic analysis was performed using cultured cells from amniotic fluid, skin, placenta, umbilical cord, and cord blood. RESULTS: Repeated amniocentesis revealed a mosaic tetrasomy 12p level of 25% (10/40), cultured cord blood lymphocytes had no mosaicism, cultured skin fibroblasts had a mosaic tetrasomy 12p level of 52.5% (21/40), umbilical cord fibroblasts had a mosaic tetrasomy 12p level of 72.5% (29/40), and the placental cells had a mosaic tetrasomy 12p level of 2.5% (1/40) on conventional cytogenetics. An aCGH analysis revealed that the increases in gene dosage in 12p for uncultured amniocytes, skin, and cord blood were the log2 ratios of 0.9, 0.7, and 0.7, respectively. Interphase FISH on uncultured amniocytes revealed a mosaic level of 73.1% (49/67) (tetrasomy 12p: 33; hexasomy 12p: 16). Interphase FISH analysis of stimulated cultured cord blood lymphocytes revealed a mosaic level of 58.3% (60/103) (tetrasomy 12p: 51; hexasomy 12p: 9). CONCLUSION: In the diagnosis of PKS by conventional culture cytogenetics, cord blood samplings and placental samplings are prone to a negative result when compared with amniocentesis. Whenever cord blood sampling is applied for prenatal diagnosis of PKS, aCGH on uncultured cord blood or interphase FISH on cultured cord blood can be used for the diagnosis, in addition to conventional cytogenetics.
