HABP2 and breast cancer: rs2089176 (HABP2) and rs9302903 (LINC01483) were associated with breast cancer risk in BCAC meta-analysis data (rs2089176 OR [95% CI] per minor allele increase = 0.98 [0.97–0.99], P = 0.01; rs9302903 OR [95% CI] per minor allele increase = 0.96 [0.94–0.99], P = 1.2 × 10− 3) in a direction consistent with that observed in the pooled MD analysis for percent dense volume [rs2089176 β [SE] per minor allele increase = − 0.07 (0.01)] and absolute dense volume [rs9302903: β [SE] per minor allele increase = − 0.14 (0.02)].
