It appears to have made it to Eastern Taiwan's indigenous tribes (Ami, Yami) but not more north of this region.

Over most of the East Pacific Rim region where it is found it is limited to 1 or 2 common haplotypes in strong linkage disequilibrium.

However, in areas were mixtures of these alleles are commonly found, Persian Gulf region and India, A*3401 is relatively uncommon, scarce, or absent.

Some reports that both A*3401 and A*3402 are in the region, but questionable whether these are perpetually maintained allele frequencies are simply recent migrants.

This haplotype is found from Western Australia to Taiwan to New Zealand indicating a recent genetic linkage between these peoples.
