An expanded mouse-human hybrid cell panel for mapping human chromosome 16.

A mouse/human hybrid cell panel of human chromosome 16 has been extended to a total of 31 hybrids. These hybrids were derived from constitutional translocations and deletions ascertained during clinical cytogenetic studies. This panel of hybrids, together with four fragile sites, have the potential to divide chromosome 16 into 38 regions. Rapid detailed physical mapping of gene probes or anonymous DNA probes is possible using this hybrid panel. This hybrid cell panel also allows the physical mapping of other chromosomes with three breakpoints on chromosomes 1, 4, 11 and 13 and two on chromosomes 3, 10 and 18.
