Trisomy 16 mosaicism was found in amniotic fluid cells in a patient undergoing amniocentesis because of elevated second-trimester maternal serum alpha-fetoprotein (MSAFP) (2.80 MOM), a markedly elevated human chorionic gonadotropin level (hCG) (12.02 MOM), and a Down syndrome risk of 1:55.

Recent reports suggest an increased incidence of chromosomal abnormalities in pregnancies with amniotic fluid-cell culture failure. We retrospectively reviewed the cytogenetic results of 14,165 amniotic fluid samples processed in our laboratory from 1987 to 1996. Ninety-eight per cent of the samples
Three new cases of true mosaic trisomy 17 (MT17) were diagnosed in amniotic fluid cells. Postnatal chromosome analysis from lymphocytes did not confirm the trisomic cell line, and follow-up studies showed normal psycho-motor development of the children, in one case up to the age of 4Β½ years. We sugg
## Abstract Amniocentesis was performed on a 39βyearβold gravida 4 woman because of maternal age. Ultrasonography demonstrated a twin pregnancy, and two amniotic fluid specimens were obtained under direct ultrasound guidance. All cells analyzed from the first specimen were 46,XX. In the second spec
