BRCA2 and breast cancer: After imputation, we also found associations (albeit not statistically significant after multiple testing adjustments), between one imputed SNP at locus 12p13 (rs2255390, p = 5.0 × 10−4) and breast cancer risk for BRCA1 carriers, and two SNPs and breast cancer risk for BRCA2 carriers, namely 6p22 (chr6:28226644:I, p = 9.0 × 10−4) and 8q11 (rs189286892, p = 2.0 × 10−4).
