目前 ,对乙型肝炎病毒 (HBV)的S基因变异的研究 ,仍然是国内外关注的热点。S基因变异是导致HBV基因序列多样性的重要原因 ,它与乙型肝炎的各种临床表现有密切的关系。本文就S基因变异的形成机制及其医学意义做一简要综述
At present, the study of S gene variation of hepatitis B virus (HBV) is still a hot spot at home and abroad. S gene mutation is an important reason leading to the diversity of HBV gene sequence, which is closely related to various clinical manifestations of hepatitis B. This article gives a brief overview of the mechanism of S gene mutation and its medical significance
