They have detected some SNPs, mostly related to appearance, that seem to weight specially high in population structure at global levels. Interestingly they have also located an epigenetic marker that weights somewhat in the European+African vs. East Asian+Native American axis.
The most relevant population structure SNPs are by this order:
- Rs16891982, strongly related to the West Eurasian type of depigmentation (SLC45A2), and logically structured along the West Eurasian-Others axis in an almost true/false type of structure, excepting admixed populations.
- Rs535878, not yet reported at SNPedia. It is structured along the Native American vs. African American+East Asian axis, with West Eurasians and admixed populations being intermediate (but closer to Native Americans). So Native Americans (and West Eurasians to some extent) seem to have the derived allele.
- Rs13013484, again not reported in SNPedia yet. The structure runs between African Americans and East Asians. With other populations being intermediate (but except Latinos all closer to African Americans). So East Asians (specially) have the derived allele. However notice that the East Asian sample of just one individual is somewhat inconclusive.
