Our results for the CT and TT MTHFR genotypes were null, although the ORs below one that we observed are consistent with one meta-analysis (Bai et al., 2009), while another shows no association between the MTHFR C677T polymorphism and prostate cancer risk (Collin et al., 2009). The gene discussed is MTHFR; the disease is Familial prostate cancer.
