## Abstract Characterization of FRA6E (6q26), the third most frequently observed common fragile site (CFS) in the human population, determined that aphidicolinβinduced instability at FRA6E extends over a very large region (3.6 Mb). Sequence analysis identified eight genes (__IGF2R__, __SLC22A1__, _

Recently, several common fragile sites (CFSs) have been cloned and characterized, including the two most frequently observed in the human population, FRA3B and FRA16D. In addition to their high frequency of breakage, FRA3B and FRA16D colocalize with genes crossing large regions of breakage. At FRA3B
## Abstract The common fragile site, FRA3B, has been shown to be a site of frequent homozygous deletions in some cancers, resulting in loss of expression of the associated __FHIT__ gene. It has been proposed that __FHIT__ is a tumor suppressor gene that is inactivated as a result of the instability
The FRA16D, at 16q23, spans the WWOX gene and is one of the most highly expressed common fragile sites observed when DNA replication is perturbed by aphidicolin. Several lines of evidence suggest that fragile sites are regions of DNA that are unusually sensitive to interference during replication. W
