Construction and regional localization of clones from a NotI linking library from human chromosome 17q.

A NotI linking library was constructed from a somatic cell hybrid containing chromosome 17q as its only human material. A total of 112 human clones were assigned to nine regions of 17q using a somatic cell hybrid mapping panel. The library includes clones that detect the acute promyelocytic leukemia and von Recklinghausen neurofibromatosis translocation breakpoints at 17q11.2-12 and 17q11.2, respectively, on pulsed-field gel electrophoresis. The mapped clones represent over 50% of the estimated number of NotI sites on 17q, and therefore constitute an important resource for long-distance mapping.
