UGT1A7 and hepatocellular carcinoma: A more recent case-control study in a population of patients with viral HCC also found a relation between UGT1A7 low enzymatic activity and HCC; its results are quantitatively very similar to ours [2.0 (0.6–6.7) for the UGT1A7*3/*3 genotype and 2.7 (1.4–5.3) for the low enzymatic activity [5].
