However, 13 genes associated with significant higher expression in carcinoma compared with normal mucosa were not significantly upregulated in MSI tumors (HSPB1, TGFBR1, ELK1, FGF1, PDGFRB, TGFBR2, FDF18, CACNG8, NTF4, CACNG4, FGF20, ILA1A, and FGF19). This evidence concerns the gene FGF20 and carcinoma.
