Common fragile sites (CFSs) are regions of chromosomal break that may play a role in oncogenesis. The most frequent alteration occurs at FRA3B, within the FHIT gene, at chromosomal region 3p14.

FRA3B localized in the tumor-suppressor gene FHIT that is altered by deletions or loss of heterozygosity (LOH) in many cancers.
