BRCA2 and ovarian cancer: The combined analysis of stage 1 and 2 samples, and BRCA2 carriers, identified seven SNPs on the iCOGS array (pairwise r2 range: 0.68–1.00) from a 1.3 Mb (40.8–42.1 Mb, build 36.3) region of 17q21.31 that were strongly associated (P<1.27×10−9) with ovarian cancer risk (Table 4, Figure 2).
