Furthermore, there was evidence that the association between dietary MK intake and prostate cancer may be modified by the rs9934438 polymorphism of the VKORC1 gene, as evidence of an inverse association between higher dietary MK intakes and prostate cancer risk was seen in AA and AG but not GG carriers (Nimptsch et al. 2009). The gene discussed is VKORC1; the disease is prostate carcinoma.
