A total of 5700 human chromosome 3-specific cosmid clones was isolated from a series of cosmid libraries constructed from somatic cell hybrids whose only human component was an entire chromosome 3 or a chromosome 3 containing an interstitial deletion removing 50% of long arm sequences. Several unique sequence chromosome 3-specific hybridization probes were isolated from each of 616 of these cosmids. These probes were then used to localize the cosmids by hybridization to a somatic cell hybrid deletion mapping panel capable of resolving chromosome 3 into nine distinct subregions. All 616 of the cosmids were localized to either the long or short arm of chromosome 3 and 63% of the short arm cosmids were more precisely localized. We have identified a total of 87 cosmids that contain fragments that are evolutionarily conserved. Fragments from these cosmids should prove useful in the identification of new chromosome 3-specific genes as well as in comparative mapping studies. The localized cosmids should provide excellent saturation of human chromosome 3 and facilitate the construction of physical and genetic linkage maps to identify various disease loci including Von Hippel Lindau disease and renal and small cell lung carcinoma.
