PG - 173-9 AB - We have constructed a physical map of chromosome band 17p13, using 29 markers that had been localized to 17p13 by means of fluorescence in situ hybridization (FISH) and analysis by pulsed-field gel electrophoresis (PFGE). The map spans nearly 8 Mb of genomic DNA, and the estimated average distance between each marker is roughly 290 kb. The p13 band of chromosome 17 is thought to contain a putative tumor suppressor gene in addition and distal to TP53. Deletion mapping in a large number of breast carcinomas indicated that the tumor suppressor gene lies between the loci defined by cC117-708 (D17S878) and p144D6 (D17S34), which are an estimated 7 Mb apart. Our results should contribute to construction of a contig map of chromosome band 17p13 with cosmid and/or YAC (yeast artificial chromosome) clones, and to isolation of the putative tumor suppressor gene.
