CDK1 and breast cancer: In CDK1, women harboring the 5-SNP haplotype ATATT (rs2448343, rs3213048, rs3213067, rs1871446, and rs10711), which carried 2 low-risk alleles of rs2448343 and rs1871446, had only 78.6% of BC risk compared with those harboring common haplotype GCACG (OR=0.786, 95% CI=0.646-0.957, P=0.017, Table S3).
