Expression of fragile-X in a female fetus diagnosed after chorionic villus sampling.
Study of different tissues of an aborted female fetus showed similar levels of fragile-X expression (6.3-9.2 per cent) and of early replication of the FRAXA-positive cells (50-66 per cent) in fetal tissues. Different culture media did not significantly affect either investigation. It is suggested that the distribution of X-inactivation in FRAXA-positive chorionic villus cells of a female fetus might indicate her future phenotype.
