Comparing the genotype combination of rs1799883 (FABP2) and rs3813865 (CYP2E1) revealed that individuals with the wild type (GG) at FABP2 and the heterozygous (GC) genotype at CYP2E1 had a significantly higher incidence of CRC development (P = 0.02) (Table 2). This evidence concerns the gene CYP2E1 and colorectal carcinoma.
