FEN1 and colorectal carcinoma: We analyzed only 14 genes that all had non-zero expression in at least 80% of the samples (Figure 6C,D), and observed that genes located near rs174546—including FADS1, FADS2, FADS3, and FEN1—were significantly upregulated in CRC tissues compared to normal tissues (p = 1.5 × 10−9, 3.3 × 10−6, 2.80 × 10−9, and 5.90 × 10−16, respectively).
