摘要: BRCA1 and BRCA2 germ-line mutations predispose to breast ovarian cancer. Large genomic rearrangements of account for 0-36% all disease causing in various populations, while large are more rare. We examined 642 East Danish and/or cancer patients whom a deleterious mutation was not detected by sequencing using the multiplex ligation-dependent probe amplification (MLPA) assay. identified 15 with 7 different rearrangements, including exon 5-7 deletion novel breakpoint, 13 duplication, 17-19 deletion, 3-16 20 breakpoint as well two 17-18 19 deletions. The accounted 9.2% (15/163) Denmark. Nine had BRCA1. By SNP analysis we find that share 5 Mb fragment chromosome 17, BRCA1, indicating represents founder mutation.
