HLA allele frequencies

[D. Koelle]

Does anyone know of a web site where one can ask simple questions about
HLA allele frequency

sample query:

What proportion of US caucasions have HLA A*0201?
What proportion of African Americans have HLA B*2701?

This info. is in some obscure books but hopefully it has made it on-line.
Please email me any leads or post to the group if it is of general
interest. Thanks very much
