    Abstract:
    The tuberous sclerosis disease gene TSC1 has been mapped to 9q34. However, its precise localisation has proved problematic because of conflicting recombination data. Therefore, we have attempted to clone the entire target area into cosmid contigs prior to gene isolation studies. We have used Alu-PCR from irradiation hybrids to produce complex probes from the target region which have identified 1,400 cosmids from a chromosome-specific library. These, along with cosmids obtained by other methods, have been assembled into contigs by a fingerprinting technique. We estimate that we have obtained most of the region in cosmid contigs. These cosmids are a resource for the isolation of expressed genes within the TSC1 interval. In addition, the cosmid contig assembly has demonstrated a number of previously unknown physical connections between genes and markers in 9q34.
