Abstract

The genotypes of hepatitis B virus (HBV) have a distinct geographical distribution, with HBV genotype H being very rare in East Asia, including Japan. We herein report the case of a 12-year-old Japanese female with hepatocellular carcinoma (HCC) who exhibited HBV genotype H. Notably, the HBV isolated from the patient had a deletion mutation in the pre-S2 region. The genome of HBV genotype H in the patient with HCC has not been analyzed in detail. The deletion mutations in the pre-S2 region, which may play an important role in hepatocarcinogenesis in children, can also present in genotype H.

摘要

乙型肝炎病毒（HBV）的基因型具有独特的地理分布，其中HBV基因型H在包括日本在内的东亚地区非常罕见。我们在此报告一例患有肝细胞癌（HCC）的12岁日本女性病例，该患者表现为HBV基因型H。值得注意的是，从该患者分离出的HBV在前S2区域存在缺失突变。尚未对该HCC患者的HBV基因型H基因组进行详细分析。前S2区域的缺失突变可能在儿童肝癌发生中起重要作用，也可能出现在基因型H中。
