Abstract

The distal part of 11q13, which contains several genes relevant to human diseases, has been poorly mapped as part of genome-wide mapping efforts. In the prospect of drawing a fine-scale integrated map of the area containing KRN1 and OMP, we have established a framework of markers by hybridization to DNA of somatic cell hybrids and by fluorescence in situ hybridization (FISH) on metaphase chromosomes. The probes studied were used to isolate 27 YACs and 16 cosmids that could be organized in three contigs covering approximately 6 Mb. These contigs were separated by two gaps that are likely to contain sequences underrepresented in YAC libraries. They were then integrated based on long-range restriction mapping and DNA-fiber FISH into a high-resolution physical map, which covers a 5.5-Mb region and includes 36 anonymous markers and 10 genes. This map will be used to search for genes within the 2/3 of this region where none have been localized as yet. It will also lay the ground for the characterization of an amplicon surrounding GARP in breast cancer and for the search of disease genes within this region.
