Discussion: Among the 11 HBV S gene truncation mutants we have identified (sL15*, sL21*, sS61*, sC69*, sL95*, sW156*, sW163*, sW172*, sW182*, sW196*, and sL216*) in HBV-related PMID: 22666402

Result: Of note, a substantial part of these substitutions (4 out of 9) resulted in stop codons (*) (sW156*, sW163*, sW165* and sW172*), giving rise to proteins with significant aa deletions.
