| Popis: | Fluorescence in situ hybridization (FISH) and molecular analyses of synovial sarcomas with cytogenetically similar (X;18)(p11.2;q11.2) translocations have revealed two alternative breakpoint regions in Xp11.2, one residing in the ornithine aminotransferase-like 1 (OATL1) region and the other one in the related but distinct OATL2 region. As these results were obtained by different groups, we set out to evaluate an extended series of tumors with special emphasis on the two possible X-related breakpoint regions. Together, seven synovial sarcomas were identified with a break in the OATL1 region and six with a break near OATL2, thereby confirming the actual existence of the two alternative Xp breakpoint regions. We speculate that there seems to be a relationship between the occurrence of these breakpoint regions and the histologic phenotype of the tumors, with a predominance of OATL1-related breakpoints in the classical biphasic tumors and of OATL2-related breakpoints in the monophasic fibrous tumors. |
