However, under the log-additive model, the haplotype FtCA (FokI F, TaqI t, VDR-5132 C and Cdx2 A) was significantly associated with breast cancer risk compared with the most common haplotype FTCG (OR = 1.43, 95% CI = 1.00 to 2.05; Table 5). This evidence concerns the gene CDX2 and breast carcinoma.
