Among EA women, similar results were found for haplotypes containing rs11608702 in VDR and haplotypes containing rs3787555 in CYP24A1. The commonly studied haplotype in the 3' untranslated region of VDR consisting of Taq1, Apa1, and Bsm1 was not associated with breast cancer risk in AA women, but a modest decreased risk was observed in EA women and significance was marginal (OR = 0.82, 95% CI = 0.67 to 1.02). Here, CYP24A1 is linked to breast cancer.
