  • Title: A genetic analysis of the Werner syndrome region on human chromosome 8p.
    Author: Thomas W, Rubenstein M, Goto M, Drayna D.
    Journal: Genomics; 1993 Jun; 16(3):685-90. PubMed ID: 8325642.
    Abstract:
    Werner syndrome (WRN) is an inherited disorder that produces symptoms of premature aging. This disease is caused by a recessive mutation that has previously been mapped to chromosome 8p. We have now used genetic linkage analysis to map the WRN gene relative to chromosome 8 reference loci, to screen candidate genes, and to identify a novel dinucleotide repeat polymorphic marker closely linked to WRN. The WRN locus was mapped relative to the marker loci, PLAT, ANK1, D8S135, and D8S87 of the comprehensive chromosome 8 linkage map. The heregulin (HRG) and the fibroblast growth factor receptor 1 genes (FGFR1) have been mapped to chromosome 8p and are involved in cellular growth. Recombination events were detected between WRN and the HRG and FGFR1 genes, excluding them as candidates for the WRN gene. A polymorphic marker generated in this study, WT251, is linked to WRN at a recombination fraction of 0.006, with a lod score of 16.5.
