AbstractRecent developments in genetic linkage mapping of the human genome have generated a large number of short tandem repeat polymorphic markers (Weissenbach et al. 1992, Gyapay et al. 1994), and eventual integration of these markers into a physical map is a logical progression. A number of Généthon microsatellite (CA repeat) markers have been provisionally localized to 1p13, but their exact position with respect to other sequences is unknown. In order to confirm the order of these markers and their position with respect to known genes within 1p13 and the centromere, we have isolated yeast artificial chromosomes (YACs) corresponding to the markers and have carried out double and triple fluorescence in situ hybridization (FISH) studies. Knowledge of both the order of microsatellite markers and their integration with a physical map of known genes can be an essential component in analysis of disease loci such as human cancer, where regions of chromosomes showing high levels of loss of heterozygosity need to be mapped in detail.
