Loss of DNA sequences within human chromosomal band 7q31.2 is frequently observed in a number of different solid tumors including breast, prostate, and ovarian cancer. This chromosomal band also contains the common fragile site, FRA7G. Many of the common fragile sites occur within chromosomal regions that are frequently deleted during tumor formation but their precise position, relative to the chromosome breakpoints and deletions, has not been defined for the majority of the fragile sites. Because the frequency of expression of FRA7G is low, we analyzed the expression of FRA7G in a chromosome 7-only somatic cell hybrid (hamster-human). YAC clones defining a contig spanning 7q31.2 were then used as FISH probes against metaphase spreads prepared from the hybrid cells after aphidicolin induction. This analysis quickly revealed whether a specific YAC clone mapped proximal, distal, or actually spanned the region of decondensation/breakage of FRA7G. By using this approach, we have identified several overlapping YAC clones that clearly span FRA7G. Interestingly, these clones map precisely to the common region of LOH in breast cancer and prostate cancer. In addition, the MET oncogene is contained within the three YACs that span FRA7G.
