Furthermore 16 out of 70 genes are involved in viral carcinogenesis pathway (CDKN1A, CDKN1B, HIST1H4K, HIST1H4L, HIST1H4A, NRAS, HIST1H4B, CASP3, HIST1H4H, HIST1H4J, HIST1H4C, HIST1H4D, TP53, HRAS, HIST1H4E and HIST1H4F) and 17 in pathways in cancer (CDKN1A, CDKN1B, TGFB1, EGF, ADCY8, GNG12, NRAS, FGF9, AKT2, CASP3, AKT1, PLCB1, BID, WNT1, TP53, HRAS and FGF23). Here, HRAS is linked to cancer.
