PG - 210-22 AB - We report here the physical mapping of recurrent chromosome 12q13-q15 breakpoints in cell lines derived from primary myxoid liposarcoma, lipoma, uterine leiomyoma, and pleomorphic adenoma of the salivary glands. In fluorescence in situ hybridization (FISH) experiments, we first mapped the position of the chromosome 12 translocation breakpoint in uterine leiomyoma cell line LM-30.1/SV40 relative to loci COL2A1, D12S4, D12S17, D12S6, D12S6, D12S19, D12S8, and D12S7. It mapped between linkage probes CRI-C86 (D12S19) and p7G11 (D12S8). We then isolated YAC clones using CRI-C86- and p7G11-derived sequence-tagged sites, constructed corresponding YAC contigs of 310 and 800 kb, respectively, and established long-range physical maps of these. Cosmid clones LLNL12NCO1-98C10 and LLNL12NCO1-113D12 were isolated using STSs within the CRI-C86- and the p7G11-derived YAC contigs, respectively, and a mixture of them was used to routinely study the various tumor cell lines by FISH analysis. The chromosome 12 breakpoints of all tumor cell lines tested mapped between cosmids LLNL12NCO1-98C10 and LLNL12NCO1-113D12. None of the breakpoints appeared to map within any of the isolated YAC clones. Furthermore, FISH analysis using cosmid LLNL12-NCO1-144G3, which maps at the CHOP locus, revealed that the chromosome 12 breakpoints in all cell lines of the three benign solid tumors that were tested were located distal to the chromosome 12 translocation breakpoint with the CHOP gene in myxoid liposarcoma cells with t(12;16). In conclusion, our studies seem to indicate that the chromosome 12 breakpoints of myxoid liposarcoma, lipoma, uterine leiomyoma, and pleomorphic adenoma of the salivary glands are all clustered within the 7-cM interval between D12S19 and D12S8, with those of the benign solid tumors distal to CHOP. Finally, the MYF5 gene mapped telomeric to LLNL12NCO1-113D12, and the MIP gene mapped centromeric to the chromosome 12 translocation breakpoint in myxoid liposarcoma cells.
