The CEPH consortium primary linkage map of human chromosome 10.

The first CEPH consortium map, that of chromosome 10, is presented. This primary linkage map contains 28 continuously linked loci defined by genotypes generated from CEPH family DNAs with 37 probe and enzyme combinations. Cytogenetic localization of some of the genetic markers indicates that the consortium map extends, at least, from 10p13 to 10q26. The order of loci on the consortium map agrees with the physical localization data. The female map spans 309 cM (206 cM if an approximation of interference is included in the mapping function used to construct the map), and the mean genetic distance of intervals is 11 cM (7 cM). Also presented are maps of chromosome 10 from each of five CEPH collaborating laboratories, based on genotypes for all relevant markers in the CEPH database. The CEPH consortium map of chromosome 10 should be useful for localization of any gene of interest falling within the span covered. The genotypes in the chromosome 10 consortium map database are now available to the scientific community.
