Replication error in human breast cancer: Comparison with clinical variables and family history of cancer
Replication errors (RER) at microsatellite repeats indicate genomic instability in hereditary nonpolyposis colorectal cancer (HNPCC) and in some sporadic cancers. We have studied genomic instability in 313 sporadic breast tumors and in 106 tumors from BRCA2, 999del5 carriers at 43 genomic loci on 13...
