Fetal fraction estimate in twin pregnancies using directed cell-free DNA analysis.
OBJECTIVE To estimate fetal fraction (FF) in monozygotic and dizygotic twin pregnancies. METHODS Maternal plasma samples were obtained from 35 monochorionic twin pregnancies with male fetuses (monozygotic) and 35 dichorionic pregnancies discordant for fetal sex (dizygotic) at 11-13 weeks' gestation.

The girl presented with Down syndrome, aplasia of the uterus and the Fallopian tubes and normal female external genitalia. We propose that the lack of Müllerian struc...
