Prenatal diagnosis of trisomy 20 mosaicism. 1979

N B Kardon, and E Lieber, and J G Davis, and L Y Hsu

Three cases of trisomy 20 mosaicism in amniotic fluid cell cultures are described. Two of the pregnancies resulted in normal full-term infants. The third pregnancy was terminated and revealed a phenotypically normal fetus. A review of five previously reported cases is presented. Explanations of these findings include in vitro nondisjunction, culture of extraembryonic tissue, and true fetal mosaicism. The diagnostic dilemma this presents is discussed.
