Unbalanced chromosome translocations with breakpoints around 8p12, resulting in loss of distal 8p, are common in carcinomas. We have mapped the 8p12 breakpoints in three breast cancer cell lines, T-47D, MDA-MB-361, and ZR-75-1, using YACs and PACs between D8S540 and D8S255 by fluorescence in situ hybridization. All three lines had a breakpoint close to D8S505, proximal to HGL. Each breakpoint was distinct, but all were within 0.5 to 1.5 Mb of each other. The T-47D cell line had a straightforward translocation, but in MDA-MB-361 and ZR-75-1 the translocations were accompanied by local rearrangements of surprising complexity. Small regions of 8p from close to the breakpoint were duplicated or amplified as inserts in the attached chromosome fragment. ZR-75-1 also had retained a separate fragment of about 1 Mb, from the region 1 to 3 Mb telomeric to the common breakpoint, that included HGL. This line also had an interstitial deletion several megabases more centromeric. The data suggest that breakpoints on 8p12 are clustered in a small region and show that translocations breaking there may be accompanied by additional rearrangements.
