title: A 3-Mb contig from D11S987 to MLK3, a gene-rich region in 11q13.
abstract: We have combined genetic, radiation-reduced somatic cell hybrid (RRH), fluorescent in situ hybridization (FISH), and physical mapping methods to generate a contig of overlapping YAC, PAC, and cosmid clones corresponding to > 3 continuous Mb in 11q13. A total of 15 STSs [7 genes (GSTP1, ACTN, PC, MLK3, FRA1, SEA, HNP36), 4 polymorphic loci (D11S807, D11S987, GSTP1, D11S913), 3 ESTs (D11S1956E, D11S951E, and W1-12191), and 1 anonymous STS (D11S703)], mapping to three independent RRH segregation groups, identified 26 YAC, 7 PAC, and 16 cosmid clones from the CGM, Roswell Park, CEPH Mark I, and CEPH MegaYAC YAC libraries, a 5 genome equivalent PAC library, and a chromosome II-specific cosmid library. Thirty-six Alu-PCR products derived from 10 anonymous bacteriophage lambda clones, a cosmid containing the polymorphic marker D11S460, or STS-positive YAC or cosmid clones were identified and used to screen selected libraries by hybridization, resulting in the identification of 19 additional clones. The integrity and relative position of a subset of clones was confirmed by FISH and were found to be consistent with the physical and RRH mapping results. The combination of STS and Alu-PCR-based approaches has proven to be successful in attaining contiguous cloned coverage in this very GC-rich region, thereby establishing for the first time the absolute order and distance between the markers: CEN-MLK3-(D11S1956E/D11S951E/W1-12191)-FRA1-D 11S460-SEA-HNP36/ D11S913-ACTN-PC-D11S703-GSTP1-D11S987-TEL.
