CCNB1 and breast cancer: However, in CCNB1, the 4-SNP haplotype pairs (diplotype) TAGT/TAGT (rs350104, rs2069429, rs164390, and rs2069433), which carried the minor allele homozygotes of the risk SNP rs2069429, could increase about 1.95-fold of BC risk (OR=1.947 95% CI=1.154-3.284, P=0.013, Table S3) compared with common diplotype TGTT/CGGT.
