There was no evidence of an underlying liver disease upon serological examination, and tumor markers, including carcinoembryonic antigen (CEA) and carbohydrate antigen (CA-199), were negative, with the exception of α-feto protein (AFP) which was present at 13.14 μg/l (range, 0–7 μg/l). The gene discussed is CEACAM5; the disease is liver disorder.
