An improved technique for inducing fra(X) expression in cultured cells was obtained by using diazepam for mitotic arrest and 5-fluorodeoxyuridine (FUdR) for the induction of fra(X) expression. The method was developed using cultured fibroblast and urinary cells from fra(X) patients. Prenatal studies were performed on cultured amniotic fluid cells in five pregnancies at risk for fra(X). In two cases the cultured cells showed a 46,XY, fra(X) karyotype. One of the pregnancies was terminated and the diagnosis was confirmed by chromosome studies on several fetal tissues including chorionic villi and by histopathologic changes in the lymphatic vessels of the fetal testes. The fra(X) was also demonstrated in chorionic villi in a case in which amniotic fluid cells were not studied. Chorionic villi were isolated after a spontaneous abortion, the cultured cells had a 45,X karyotype and in addition 5% of the cells were fra(X) positive.
