Result: A336C/
A336T/
T337C variations occurred in 40/166(24.1%)
chronic hepatitis B patients without any antiviral therapy (See Table 2).
Discussion: Statistical analysis showed
A336C/
A336T/
T337C variations were closely associated with
G1896A
Discussion: Therefore,
A336C/
A336T/
T337C variations were proposed to be another major mechanism to explain spontaneous
HBeAg loss in the natural history of
chronic HBV infection as well as
G1896A variation and genotype B.
