Postnatal and prenatal diagnosis of fragile X syndrome is feasible by direct DNA analysis. A new approach to prenatal diagnosis of fragile X syndrome in amniotic fluid cells is described, using a rapid and simple antibody test on uncultured amniotic fluid cells. The test requires 1 ml of amniotic fluid and the results of this antibody test are available on the same day as the amniocentesis.
