  1. These mutations were identified using two online tools Geno2Pheno HBV database (HBVdb) (https://hbv.geno2pheno.org/) and HBVseq program from HIV Stanford database (https://hivdb.stanford.edu/HBV/HBVseq/development/HBVseq.html). The mutations are listed for each of the sample where they occurred
