ABSTRACT
OBJECTIVE@#To carry out prenatal diagnosis for two cases of Pallister-Killian syndrome (PKS) using combined chromosomal microarray analysis (CMA) and fluorescence in situ hybridization (FISH).@*METHODS@#Umbilical cord blood was sampled from the two fetuses and subjected to G-banding chromosomal karyotyping, CMA and FISH assay.@*RESULTS@#Chromosomal karyotyping showed that the two fetuses were mos 47,XX,+i(12)(p10)[3]/46,XX[197] and mos 47,XY,+i(12)(p10)[5]/46,XY[95], respectively. CMA showed that both had carried duplication of 12p. The results of interphase FISH confirmed mosaicism of 12p tetrasomy. Combined with ultrasonographic findings, both fetuses were diagnosed as PKS.@*CONCLUSION@#Prenatal ultrasound examination, karyotype analysis of umbilical cord blood, G-banded chromosomal analysis, CMA and FISH may be used in conjunct for the prenatal diagnosis of PKS.
