title: High density deletion mapping of bladder cancer localizes the putative tumor suppressor gene between loci D8S504 and D8S264 at chromosome 8p23.3.
abstract: Deletion of chromosome 8p is associated with the progression of bladder cancer. To identify the putative tumor suppressor gene locus we have analyzed 145 bladder cancers with 12 microsatellite markers for allelic changes at the chromosome 8p23.3 region. We mapped the smallest overlapping deletion to approximately 0.7 cM genetic distance between loci D8S504 and D8S264. Allelic changes at this region occurred in 75 (52%) of the 145 tumors. We found a significant correlation between alterations at chromosome 8p23.3 and the tumor grade. The correlation between genetic changes and tumor stage reflected the distribution of tumors of different grades in each pathologic stage.
