| abstractText | In this study we have utilized human elastin cDNAs in molecular hybridizations to establish the chromosomal location of the human elastin gene. First, in situ hybridizations were performed with metaphase chromosomes from phytohemagglutinin-stimulated human peripheral blood lymphocytes. In three separate experiments using two different regions of human elastin cDNAs, the distribution of grains was found to be concentrated on the long arm of chromosome 7 within the [q11.1-21.1] region, and the peak number of grains coincided with the locus 7q11.2. Second, hybridizations with a panel of human-rodent cell hybrids showed concordance with human chromosome 7. Third, PCR analyses with elastin-specific primers of DNA from a hybrid cell line containing chromosome 7 as the only human chromosome yielded a product of the expected size, while DNA containing human chromosome 2, but not chromosome 7, did not result in a product. The results indicate that the human elastin gene is located in the proximal region of the long arm of chromosome 7. The precise localization of the elastin gene in the human genome is useful in establishing genetic linkage between inheritance of an allele with a mutated elastin gene and a heritable disorder. |
