Summary of loss of heterozygosity (LOH) analysis. LOH pattern for all 40 early sporadic breast tumours (39 infiltrating ductal carcinomas and one infiltrating lobular carcinoma) for 3p markers. Each column represents a tumour and each row represents a 3p microsatellite marker listed in descending order from telomere (D3S1304) to centromere (D3S1254). The cases are arranged from left to right in decreasing order of chromosome 3p deletions. Status of each 3p locus is indicated: black circles, loss; white circles, retention; no symbols, uninformative loci.
