The expressions of 127 genes in tumor and nontumor samples and 26 genes, including ABCA2, ABCA3, ABCA4, ABCC1, ABCD1, ACSL1, AKR1D1, ALDH8A1, BBOX1, CYP39A1, CYP7A1, DIO2, EFHC1, FADS1, FADS2, GNPAT, KLF1, LIPE, NPC1, PEX6, PFKM, SLC27A5, SLC29A1, SLC35B2, SLC51B, and SLCO1B3, were identified under the criteria of fold change > ∣2∣ and adjusted P value < 0.05 (false discovery rate (FDR) < 0.05) (Figure 1(a)) [27]. The gene discussed is PEX6; the disease is neoplasm.
