Abstract

A panel of 93 radiation-reduced hybrids have been screened using PCR amplification and oligonucleotide primers for sequence-tagged sites (STSs) specific for 114 single-copy loci mapping to the short arm of chromosome 9. An x-ray dose of 6,000 rads gave an average retention frequency of approximately 23%. We have constructed a framework map containing 31 markers ordered by analyzing coretention patterns, with support for the order greater than 1,000:1. In addition, we have placed the remaining markers which could not be mapped to a single interval with this support to a range of intervals on the framework map. The STS oligonucleotide primers used in the construction of the radiation hybrid (RH) map have been used to isolate and order yeast artificial chromosomes (YACs) assigned to 9p identified from the CEPH megaYAC library. Eighty-nine STS markers have screened positive with at least one YAC. A total of 88 individual YACs (with an average size of 0.9 MB) have been placed on the map in a series of contigs and in some cases mapped cytogenetically by fluorescence in situ hybridization. Additionally, the YAC information has been used in conjunction with the RH framework placements to generate an integrated map containing 65 loci including 51 uniquely positioned markers, with an average resolution of 0.79 Mb.
