Mapping of seven polymorphic loci on human chromosome 13 by in situ hybridization.

Human chromosome 13 loci homologous to seven recombinant DNA probes were mapped using in situ hybridization of 3H-radiolabeled probes to metaphase chromosomes. Each of these seven probes reveals at least one restriction fragment length polymorphism, and thus each probe is potentially valuable in a genetic linkage map of this autosome. The data presented in this paper map the seven loci to specific regions of chromosome 13. This mapping should allow a future comparison of genetic distance with physical distance on this chromosome, and may permit better utilization of these probes in the clinical diagnosis of human chromosomal rearrangements involving chromosome 13.
