European genetic structure, study du jour

Yet another one.
As usual, Dienekes and Razib have talked about this one on their blogs.

Anything new or particularly interesting?
  • within-Germany resolution (see figure, labeled by Razib)
  • big sample, of nearly 6000
  • LCT (lactase), HERC2 (eye color and hair color) and HLA (immune function) regions stood out as most highly correlated to the North-South gradient.
  • they frame the importance of this in relation to picking appropriately matched controls in case-control studies
Ethnicity/country origin of subjects is taken as where the sample was obtained. This is unfortunate since more detailed information on the origin of each subject could have enabled better resolution.
