| Abstract: | The progesterone receptor gene (PGR), the gene coding for porphobilinogen deaminase (PBGD), the gene coding for a neural cell adhesion molecule (NCAM), the oncogene ETS1, and the anonymous genomic sequence D11S29 have been previously located on the long arm of chromosome 11. However, gene localizations obtained with different gene-mapping procedures have led to occasional discrepancies. To localize these genes more precisely, we hybridized five human DNA sequences with different chromosomal rearrangements, including four balanced and one unbalanced translocations. We show here that the order of these five sequences is cen-PGR-PBGD-DIIS29/NCAM/ETS1-tel. |
