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). The gene discussed is CACNG4; the disease is carcinoma.
