Localization of the human angiogenin gene to chromosome band 14q11, proximal to the T cell receptor alpha/delta locus.
The gene encoding angiogenin, a potent inducer of blood vessel formation, has been localized within the human genome. It is present as a single copy per haploid genome and is located on chromosome 14, on the basis of discordancy analysis of human-rodent hybrid cell lines. This localization was refined to 14q11 by in situ hybridization of an angiogenin probe to metaphase chromosomes prepared from both normal human lymphocytes and RPMI 8402 cells. The results from the RPMI 8402 cells also establish that the angiogenin gene resides proximal to a translocation breakpoint within the T cell receptor alpha/delta locus and therefore upstream from that locus. An AvaII RFLP, present at a frequency of 29% in an unselected collection of human placental DNAs, was identified in the coding region of the gene and results from a single silent transversion.
