Ten IA genes, KITLG (stem cell factor), KLRD1, CCL14, CYP2C9, CD226, CBX8, LPCAT1, RAB24, CAPG, and MSC, are dysregulated in the three comparisons of cancer samples with normal samples (HCC samples from drinkers with HBV infection vs. normal samples, HCC samples from drinkers without HBV vs. normal samples, and HCC samples from nondrinkers with HBV vs. normal samples). The gene discussed is CYP2C9; the disease is cancer.
