  • Title: A mouse-human hybrid cell panel for mapping human chromosome 16.
    Author: Callen DF.
    Journal: Ann Genet; 1986; 29(4):235-9. PubMed ID: 3495225.
    Abstract:
    A mouse-human hybrid cell panel for human chromosome 16 was constructed from human cell lines with breakpoints on chromosome 16 at p13.11, q13, q22 and q24. Fusions with the human fibroblast line GM3884, t(X;16)(q26;q24) allowed the isolation of clones with either the derivative X or the derivative 16 as the only human chromosome. This was a consequence of both the genes APRT and HPRT being involved in the translocation. The breakpoints of the line GM3884 were confirmed by aphidicolin induction of the common fragile site at 16q23. The results of the fusions with this line suggest a localisation of the APRT gene at 16q24 and confirm the localisation of HPRT to Xq26 to Xq27.3. These hybrid cell lines enable the localisation of genes and DNA fragments to six clearly defined regions. Further localisation within three of these regions is possible by use of the three fragile sites on chromosome 16. In situ hybridisation with the probe pBLUR confirmed that of three lines tested all contained a single human chromosome.
