Abstract excerpt
We have used FISH to determine the level of synchronisation in replication timing of four pairs of alleles, unrelated to chromosome 21 (p53, HER2, RB1, and c-myc), in foetal (amniotic fluid) cell samples of Down syndrome and in normal foetuses. All samples derived from the Down syndrome subjects showed large temporal differences in replication timing, in contrast to the high level of synchrony shown in all...
