The complete genome of HBoV has yet to be determined. Until today at least 5,309 nt were identified (GeneBank Accession-Number EU 984244). The genome of other parvoviruses is flanked by palindromic hairpin structures essential for DNA replication and it can be assumed that this is also true for HBoV. The hairpin structures of HBoV could not be deciphered by sequencing methods so far and the complete sequence of the genome remains unknown until the flanking structures are elucidated.
