Fragile sites are unrelated to reciprocal translocation breakpoints

In 492 cases of reciprocal translocations in balanced carriers, the 984 breakpoints were studied for a possible relationship to the 45 fragile sites. Random coincidence was predicted at 14% and the observed coincidence was 14.3%, indicating that the two events are unrelated. However, chromosomes 1, 11 and 14 were exceptions and did show a statistically significant relationship.
