Associations with breast or ovarian cancer risk for loci previously reported to be associated with cancer risk for BRCA1 mutation carriers.

Freq = frequency of allele 2 in unaffected BRCA1 carriers.HR = Per allele Hazard Ratio associated with allele 2, under a single disease risk model, unless specified.r2: correlation between the SNP in the present study and the published SNP.*SNP not in BRCA1 GWAS SNP allocation on iCOGS chip.a: rs13387042 was previously found to be associated only under the 2-df model.b: analysis under a competing risks model.
