Framework for a physical map of the human 22q13 region using bacterial artificial chromosomes (BACs)
- California Institute of Technology, Pasadena, CA (United States); and others
Detailed physical maps of entire chromosomes based on combined genetic, cytogenetic, and structural information are essential components for positional cloning and genomic sequencing. Despite the wealth of genetic information of the known diseases in the chromosome 22q13 region, the construction of a detailed physical map of the terminal region is difficult due to the sparsity of the genetic markers. We present here a map of bacterial artificial chromosome (BAC) contigs that cover a number of genetic loci in the 22q13 region. One hundred thirty-six BACs with an average insert size of 140 kb are assembled into 35 contigs defined by 64 markers in 22q13-qter. Twenty-three anonymous markers are now linked to the previously mapped genetic anchor points. 55 refs., 4 figs., 3 tabs.
