A second-generation YAC contig map of human chromosome 12.
Human chromosome 12 constitutes approximately 4.5% of the human genome and has an estimated size of 135 million base pairs (Mb). We have started to construct a high-resolution physical map of chromosome 12 as overlapping yeast artificial chromosomes (YACs), using as a foundation the first-generation physical map of this chromosome covers nearly 102 Mb of DNA and includes 426 highly polymorphic, monomorphic and gene-based markers. We also mapped 119 of the YACs, most of which are part of the physical map, by cytogenetic methods. Thus the map integrates genetic, physical and cytogenetic data and provides information about the organization of this chromosome and will help in the localization and cloning of disease-related genes. The strategy used here to generate the chromosome-12 map could be applied for the rapid construction of physical and expression maps for other human chromosomes.
