Among VDR polymorphisms, the most frequently investigated for their association with various cancers are FokI (exon 2, rs10735810), which results in an altered translation start site and has been shown to be functionally relevant [51], and BsmI (intron 8, rs1544410), which seems to be associated with different diseases, although its function is still under debate [52,53]. Here, VDR is linked to cancer.
