title: Characterization and use of somatic cell hybrids with interspecific translocations involving the human X chromosome.
abstract: Two hybrid cell lines, whose only human material was a portion of the X translocated on to a mouse chromosome, have been characterized by cytogenetics, in situ hybridization and Southern blotting. In one hybrid (HORL911R8B) the region Xpter to Xq2(2-4) was identified. In the other (PIP) the single human fragment was found to contain sequences from two separate X chromosomal regions (corresponding approximately to Xp11.4-Xp22.1 and Xq26-Xqter). These two hybrids in combination with a third (WAG 8) retaining Xqter to Xp21 as a human X-autosome translocation chromosome, form a mapping panel for rapid subregional assignments to the human X chromosome. This mapping panel has been used to provide information about the order of DNA sequences derived from the X chromosome and to provide an assignment for an anonymous DNA segment, M201 gamma, to Xp11.4-Xp21.1.
