Do you have any Aleut HLA haplotypes yet? (Seems to me you didn't the
last time we discussed this issue.)

Their mtDNA sequences (N=391) belong to 13 or more haplogroups but
about 3/4 of them would be classified as C or D. About 10% are of
non-Asian origin; possibly European.

In a fairly early Y chromosome study, some haplotypes listed for the
"Inuit Eskimos" could have been interpreted as European admixture but
I'm not 'up' on the specific details. I've found no parallel to these
in the mtDNA studies. Could you be referring to this when you mention
"western Asia"?
