For one of the novel SNPs identified in the discovery GWAS [2], ZNF365 rs16917302, there was weak evidence of association with breast cancer risk (P = 0.01); however, an uncorrelated SNP, rs17221319 (r2<0.01), 54 kb upstream of rs16917302 had stronger evidence of association (P = 6×10−3). This evidence concerns the gene ZNF365 and breast cancer.
