Regional localization of 192 genic markers on human chromosome 1

A panel of somatic cell hybrids has been used to localize 192 novel eSTS markers to seven individual subregions of human chromosome 1. The positions of the breakpoints in each of these hybrids have been determined relative to the genetic linkage map of chromosome 1, and so the approximate locations of the genes from which the eSTS markers have been derived can be determined. Although the distribution of the eSTS markers is relatively random, 23% were assigned to the 1p34-p36 region. The hybrid mapping panel does not subdivide the 1q24-q44 region, which contains 36% of the eSTS markers. This analysis, therefore, provides a series of genic markers in which to search for candidates for a variety of human genetic disorders and recessive oncogenes mapped to the same relative position on the chromosome.
