Detailed deletion mapping of chromosome arm 3p in breast cancers: a 2-cM region on 3p14.3-21.1 and a 5-cM region on 3p24.3-25.1 commonly deleted in tumors.


Loss of heterozygosity (LOH) on 3p is frequent in human renal cell carcinomas, lung cancers, and breast cancers. To define the region(s) on 3p that harbor presumptive tumor suppressor gene(s) for breast cancer, we examined 196 primary breast tumors for their patterns of LOH at 22 microsatellite marker loci distributed along this chromosome arm. Allelic loss… (More)
