I have spoken of my somewhat atypical, for a South Asian, genetic results before. Recently Dienekes performed some cluster analysis which confirmed the initial findings, while adding a little detail:
I am DOD075. The Southeast Asian component is modal in Malays, while the East Asian component is modal in the North Chinese. Vietnamese and Cambodians are mixed, with the former biased toward East Asian, and the latter Southeast Asian. My own proportions are more balanced, but there might be some noise in there. That being said, from what I have read of Southeast Asia it is highly likely that Burmese ethnicities will be between the Cambodians and Vietnamese in proportions. The Burmans were more shaped by the indigenous Mon-Khmer people than the Vietnamese were, though like the Vietnamese they seem to hail from southern China. My family is traditionally from eastern Bengal, and has been at various points the subjects of the kingdom of Tripura. Here's the Dodecad Indians, HapMap Gujaratis, and Behar et al. North Kannadans. The orange is Asian. Can you tell which one I am?
I'm pretty sure I'm second from the left. Not only am I atypically Asian, but I often show trace levels of other ancestral components in Dienekes' ADMIXTURE results (I suspect this is due a rather cosmopolitan great-grandfather who was from Delhi). In any case, so far I've had pretty general pointers of what's going on here. Unlike most people who get this stuff done, I found something interesting, though not too surprising (more on this later). But I ran into something which makes the case for specific Burmese origin even stronger. I got involved in BGA thanks to the urging of my friend Paul. Recently David of BGA sent me matches for various HGDP and other populations, as well as his own project samples, for extended haplotype blocks on the first 3 chromosomes. These are long stretches of correlated markers which haven't been broken apart by recombination. They may be indications of recent common ancestry between two individuals who share regions of genomic affinity. I decided to look at my matches. Also, there are several other South Asian individuals in the project. I don't know who they are, but it's clear they're South Asian. I was curious to compare myself to them in terms of my matches. First, I removed all the project samples. So basically I limited it to populations whose names I could perceive easily. Then I limited it to blocks of at least 100 bases. Below are the number of hits in the populations ordered. I matched some Pathans more than others, but I threw them all into a big pool. You can see some of the Genomes Unzipped guys, and Ilana Fisher & Kate Morely too.
