Result: A336C/
A336T/
T337C variations occurred in 26/87 (29.9%)
chronic hepatitis B patients with genotype B and 14/79 (17.7%) patients with genotype C, and Chi-square test showed that there was no significant difference in the rate of
A336C/
A336T/
T337C variations between HBV genotype B and C (chi2 = 3.3, P = 0.07, See Table 2).
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
