Clones were isolated from two flow-sorted chromosome 13 libraries. Twenty-five clones were localized to various regions of chromosome 13, using a well-characterized panel of rodent x human hybrid cell lines. Eight DNA markers were localized to 13q14.2→q22, where the gene for Wilson disease, a recessive disorder of copper metabolism, was previously assigned. The new markers will be useful for the diagnosis of pre-symptomatic sibs of Wilson disease patients. We isolated six DNA clones proximal to the retinoblastoma gene, a region in which a translocation associated with rhabdomyosarcoma has been observed. Probes for both of these regions will be useful for the cloning of the genes involved in these diseases.
