Abstract Background There are eight genotypes of hepatitis B virus A-H and subgenotypes are recognized. Genotyping can be accomplished based on a partial sequence of HBV genome such as the pre-S or S gene. Several methods have been developed and used for HBV genotyping. This study was undertaken to determine the HBV genotypes in Egyptian pediatric cancer patients with acute and chronic liver disease. Methods HBV genotypes were determined in 22 patients who had acute forms of liver disease AH
