Laboratory values were almost normal except for a mild anemia (hemoglobin 11.0 g/dl) and elevated levels of alpha-fetoprotein (AFP) (56.8 ng/ml; L3% 52.3%) and protein induced by vitamin K absence or antagonist II (PIVKA-II) (1228 mAU/ml); however, carcinoembryonic antigen and carbohydrate antigen 19–9 levels were normal. This evidence concerns the gene AFP and anemia (phenotype).
