title: Construction of a chromosome 15-specific linking library and identification of potential gene sequences.
abstract: We have tested a strategy for the construction of a total restriction fragment map of a human chromosome and the rapid isolation of a great number of genes from a specific chromosome. The strategy is based on the cloning of chromosome-specific CpG-rich DNA sequences which are present at the 5' end of many genes. This approach has two important implications: (i) the clones can be used to probe pulsed-field gradient gel blots and link restriction fragments generated by CpG restriction endonucleases, and (ii) the finding of tight genetic or physical linkage between one of these gene probes and a given hereditary disease would make the marker a good candidate gene for this disease. We have constructed a chromosome 15-specific linking library and identified potential gene sequences.
