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 site
s (STS) D8S339 and D8S1055, as well as a novel polymorphic STS, D8S229
7. We also refine the positions of three known gene loci, GTF2E2, GSR,
and PPP2CB, relative to the location of WRN within the map.
