Other studies have reported no modification of associations between measured or inferred vitamin D status and breast cancer by the VDR polymorphisms BsmI (Chen et al. 2005; McCullough et al. 2007), FokI (Abbas et al. 2008; Chen et al. 2005; John et al. 2007; McCullough et al. 2007), TaqI (Abbas et al. 2008; John et al. 2007; McCullough et al. 2007), or ApaI (rs7975232, also evaluated in the present study) (McCullough et al. 2007). The gene discussed is VDR; the disease is breast carcinoma.
