Finer mapping of European ancestry using personal genomic data

Dienekes has put together a neat little tool that uses variation data from either 23andMe or deCODEme to estimate whether a subject's ancestry stems mainly from Northwest European, Southeast European, or Ashkenazi Jewish populations, using a set of published markers that are strongly differentiated between these population clusters. There's more detail on how the tool operates here; to use it, you'll first need to download the R software environment from here.

Like the Promethease tool, this is a great example of how the human genomics community can help genetic testing customers wring the most out of the rich, complex trove of data in their own genome.
