CYP24A1 and colorectal carcinoma: In clinical phenotypic-genotype analysis, rs6013905 GG (P = 0.05, OR = 4.00, 95%CI: 0.92–17.48) and rs2762939 GX (P = 0.03, OR = 4.87, 95%CI: 1.00–23.69) carriers were significantly associated with poorly differentiated CRC, while CYP24A1 rs6068816 AX was significantly associated with the tumor type (P = 0.02, OR = 2.08, 95%CI: 1.10–3.96) and location (P = 0.04, OR = 2.24, 95%CI: 1.05–4.77).
