“…It is of interest that the abortion rate in our first 100 consecutive patients who have reached their due date was about 6% which in comparison to the overall results is not suggestive of a pronounced "learning curve" as observed in the beginning of other CVS programs [18,19]. This may be explained by a proper training period of more than 50 cases in a pre-diagnostic series, careful ultrasound evaluation prior to CVS and the easy handling of our new echogenic catheter.…”

Prenatal diagnosis of fragile X syndrome by placental (chorionic villi) biopsy culture

et al. 1988

Second trimester ultrasound-guided fetal blood sampling and placental biopsy were performed on 10 pregnancies at risk for fra(X)-linked mental retardation (Martin-Bell syndrome). Three cases were diagnosed as affected after cytogenetic analysis of fetal blood and placental cultures. The fra(X)(q27.3) and common fragile sites were shown to be expressed at a lower level in placenta than in fetal blood. Induction methods included methotrexate, 5-fluore2-deoxyuridine, and excess thymidine. Excess thymidine may give the best expression of fra(X)(q27.3). Enhancement of fra(X)(q27.3) expression was not shown with caffeine or 5-methoxybenzamide.
