Abstract:
:Patients with Peutz-Jeghers syndrome (PJS), an autosomal dominant disease characterized by hamartomatous polyposis of the gastrointestinal tract, are thought to be predisposed to malignancies of the digestive tract, genital tract, and other organs. Using microsatellite markers on chromosome 19p, we have closely defined the region containing the gene responsible for this disorder through linkage analysis in seven affected families. The lack of obligate recombinants at two of these loci, D19S883 and D19S878, with maximum LOD scores of 2.88 and 3.75, confirmed the localization of the PJS locus to chromosome 19. Furthermore, haplotype analysis placed the PJS locus within a 6-cM telomeric region of chromosome 19p, between D19S886 and D19S565.
