A 2.8 megabase YAC contig spanning D8S339, which is tightly linked to the Werner syndrome locus

A number of gene loci, including the locus for Werner syndrome (WRN), map to proximal human chromosome 8p near the genetic marker D8S339. In this report, we present a long range physical map of an approximately 2.8 megabase yeast artificial chromosome contig centred on D8S339. In this map, we localize the WRN-linked polymorphic sequence-tagged sites (STS) D8S339 and D8S1055, as well as a novel polymorphic STS, D8S2297. We also refine the positions of three known gene loci, GTF2E2, GSR, and PPP2CB, relative to the location of WRN within the map.Key words: WRN, GTF2E2, GSR, PPP2CB, physical map, human chromosome 8p.
