Chromosomal assignment of 14 genomic probes for highly polymorphic loci.

Over 500 probes revealing restriction fragment length polymorphisms (RFLPs) have been isolated by Schumm et al. (1988). We describe here the chromosomal assignment of 14 of the most highly polymorphic markers in that set of probes, with polymorphism information content values of up to 0.98. The probes were mapped using a panel of human x rodent somatic cell hybrids and were found to be distributed among nine different autosomes. Chromosome localization of such highly polymorphic markers has been an important step in the construction of the human genetic map, as a large number of RFLP probes has now been localized by genetic linkage studies to these loci.

Panel of twenty-five independent man-rodent hybrids for human genetic marker mapping.

To increase the efficiency of the human gene mapping, a panel of 25 man-rodent hybrids was selected out of 200 independent man-rodent hybrids produced in our laboratory since 1969. The hybrid panel was selected in such a fashion as to allow the asignment of a human marker M by respecting the two following complementary criteria: correlation between M and a chromosome and exclusion of the other chromosomes. The panel characteristics allowing the use of these two criteria were presented and discussed. A first series of enzyme markers were analysed to test the validity of the hybrid panel for the human gene mapping. The different possibilities and limits of the hybrid panel were also discussed, especially for the assignment of markers with DNA probes.
