摘要: Five cases of supernumerary marker chromosomes were identified in prenatal diagnosis as derived from 18, X, and Y. One unexpected finding was a case where the PCR positive for SRY gene while fluorescence situ hybridization two X centromeres. In another with an newborn phenotypically normal. Two women fetal mar(18) mar(Xp) decided to terminate pregnancy. The fifth pregnancy had karyotype 46,XX,-15,+der(15)t(Y:15)(q11,23;p13). A normal girl born at term.
