A genetic map of human chromosome 17p.

A genetic linkage map was constructed with 18 loci from the short arm and pericentric region of chromosome 17 typed on the CEPH reference families. The genetic map includes three markers extracted from the CEPH public database. Nine loci could be ordered using a threshold of odds of at least 1000:1 against alternative orders during the map construction process. With a reduced tolerance of 100:1, a total of 13 loci could be placed on the map spanning a distance of approximately 60 cM in females and 46 cM in males. There were statistically significant differences between the male and the female genetic maps. The order inferred from the genetic data was consistent with the physical localizations of these probes obtained from somatic cell hybrids and tumor deletion studies. This map should be useful for genetic fine mapping of 17p loci.
