FAM99A‐related DEGs mainly involved in KEGG pathway including “extracellular matrix (ECM)‐receptor interaction,” “TGF‐beta signaling pathway,” “PI3K‐Akt signaling pathway,” etc., and FAM99B‐related DEGs are mainly concerned with “phenylalanine metabolism,” “phosphatidylinositol signaling system,” “NF‐kappa B signaling pathway,” and “transcriptional misregulation in cancer” (Figure 7C,D). This evidence concerns the gene FAM99B and cancer.
