    Amniotic fluid at 31 weeks=mos47,XY,+3 (61 clones from four culture vessels)/48,XXY,+18 (one clone).,Amniotic fluid at 32 weeks=47,XY,+3 (8 clones).,Amniotic fluid reexamined=mos47,XY,+3 (44 clones)/48,XXY,+18 (one clone).,Blood=48,XXY,+18 (129 cells).,Skin fibroblasts=mos47,XY,+3 (13 cells)/48,XXY,+18 (19 cells).
    The infant had MCA and died 10 days after birth due to cardiorespiratory failure.
    Some other tissues were also studied and a variety of mosaic cell lines, including some normal cells were encountered.
