|
(20) | VDR | Apa I, BsmI, and Taq I | 133/157 a Turkish population | Prostate cancer risk was found to be increased in those whose genotypes were either the Aa or aa compared to those with the AA type [164] |

|
(22) | CYP27A1, GC, CYP27B1, CYP24A1, VDR, 7 vitamin D signaling downstream genes | 212 SNPs | 749/781 | No association with overall cancer risk except that the BsmI and rs11574143 were associated with cancer risk only in men with lower 25(OH)D levels [166] |

|
(24) | VDR | | a meta-analysis of several cancers | For prostate cancer, Caucasian men with BsmI Bb would have significant reduction in cancer risk compared with bb genotype. It also concluded that Fok1 ff would contribute to the increase in cancer risk compared with FF genotype [168] |
|
(25) | VDR | Taql, Apal, Bsml, Fok1, and CDX2 | a meta-analysis of 36 studies | The Taql t and Bsml B alleles were found to be inversely associated with the risk. the Apal a allele was contributed to the reduction of cancer risk only in Asian populations, and the Fokl f allele was contributed to increased cancer risk only in Caucasian populations [169] |
