I did a little looking but found nothing more than there are a LOT of the HLA types. Seriously though, it appears HLA-A*0201 is probably way more common (and still less than half - my guess) in HBV patients of European descent. Much less so in Asia/Africa.
You can go search pubmed (what I did) and see if you get the same impression.
