Genetic variation and significance of hepatitis B surface antigen
-
摘要: HBV复制过程中存在逆转录,容易发生基因变异,表面抗原基因变异可能影响临床诊断、病毒复制以及疫苗效果等。从S基因变异的发生机制、生物学及临床意义等方面讨论研究现状和存在的问题。既往大多数研究仅仅限于S基因片段,将来须要更多地从HBV角度对S基因变异进行研究。Abstract: Hepatitis B virus ( HBV) is prone to genetic variation because there is reverse transcription in the process of HBV replication.The gene mutation of hepatitis B surface antigen may affect clinical diagnosis of HBV infection, viral replication, and vaccine effect. The current research and existing problems are discussed from the following aspects: the mechanism and biological and clinical significance of S gene mutation. Most previous studies focused on S gene alone, so S gene should be considered as part of HBV DNA in the future research on S gene mutation.
