A locus on chromosome 17q, designated 'BRCA1,' has been identified as a predisposition gene for breast cancer. A panel of chromosome 17-specific radiation-reduced somatic cell hybrid clones has been assembled for high- resolution mapping of chromosome 17. A series of 35 markers, known to span the BRCA1 locus, were tested against this hybrid panel by PCR assays. Statistical analysis of these data yields a BRCA1 radiation hybrid map at a density sufficient to initiate YAC cloning and pulsed-field gel electrophoretic mapping of the candidate region. In addition, many of the markers reveal genetic polymorphisms and may be tested in breast cancer families and in loss-of-heterozygosity studies of sporadic breast cancers to better define the BRCA1 gene candidate region.
