To obtain DNA markers on human chromosome 1, we first isolated 500 cosmid clones from mouse A9 cells containing a human chromosome 1 tagged with pSV2neo. Of these, 186 were localized on each band of human chromosome 1 by R-banding fluorescence in situ hybridization; 118 and 68 were on the short and long arms, respectively. We performed restriction fragment length polymorphism (RFLP) analysis of these cosmid clones, and polymorphism was recognized with one or more enzyme in 43 of them. Two markers proved to have variable numbers of tandem repeats. Since several tumor suppressor genes, as well as genes responsible for hereditary disorders, may be located on this human chromosome, the DNA markers will be useful for RFLP analysis or the isolation of new genes related to various disorders.

UI MeSH Term Description Entries
D012150 Polymorphism, Restriction Fragment Length Variation occurring within a species in the presence or length of DNA fragment generated by a specific endonuclease at a specific site in the genome. Such variations are generated by mutations that create or abolish recognition sites for these enzymes or change the length of the fragment.
