Abstract

Using a parathyroid hormone (PTH) cDNA probe we found a common Pst I polymorphic restriction site 3' to the PTH gene in all ethnic groups examined. Because the PTH, insulin, and beta-globin loci have been localized to the short arm of chromosome 11 (11p) we used DNA polymorphisms adjacent to each of these three loci to determine whether they are genetically linked and to determine their order. We found that the PTH and beta-globin loci are closely linked (estimated recombination fraction, 0.07; 95% confidence limits, 0.05-0.10; lod score, 4.63; odds favoring linkage, 42,000:1). Furthermore, our findings strongly indicate that the beta-globin gene cluster lies between the PTH and insulin loci. Therefore, the gene order on 11p is centromere-PTH-beta-globin-insulin.
