FGFR2 and breast cancer: We observed statistically significant associations with CBC at four of nine SNPs previously reported to be associated with breast cancer at genome-wide significance levels (P < 10-7): rs2981582 (per-allele rate ratio (RR) = 1.20, 95% confidence interval (CI) = 1.04 to 1.40) and rs1219648 (per-allele RR = 1.25, 95% CI = 1.08 to 1.45) at 10q26 in the FGFR2 gene, rs13281615 in the 8q24 region (per-allele RR = 1.21, 95% CI = 1.04 to 1.40), and rs13387042 in the 2q35 region (per-allele RR = 1.19, 95% CI = 1.02 to 1.37).
