Abstract: Chromosome arm 12q breakpoints in seven cell lines derived from primary pleomorphic salivary gland adenomas were mapped by FISH analysis relative to nine DNA probes. These probes all reside in a 2.8 Mb genomic DNA region of chromosome segment 12q13-q15 and correspond to previously published sequence-tagged sites (STS). Their relative positions were established on the basis of YAC cloning and long range physical and STS content mapping. The 12q breakpoints of five of the cell lines were found to be mapping within three different subregions of the 445 kb DNA interval that was recently defined as the uterine leiomyoma cluster region of chromosome 12 breakpoints (ULCR12) between STS RM33 and RM98. All seven breakpoints appeared to map within the 1.7 Mb DNA region between STS RM36 and RM103. Furthermore, the chromosome 12 breakpoints of three primary pleomorphic salivary gland adenomas were also found to be mapping between RM36 and RM103. Finally, FISH analysis of two lipoma cell lines with 12q13-q15 aberrations pinpointed the breakpoints of these to relatively small and adjacent DNA segments which, as well as those of two primary lipomas, appeared to be located also between RM36 and RM103. We conclude from the observed clustering of the 12q breakpoints of the three distinct solid tumor types that the 1.7 Mb DNA region of the long arm of chromosome 12 between RM36 and RM103 is a multiple aberration region which we designate MAR.
