Dudley, J.T., Chen, R., Sanderford, M., Butte, A.J. & Kumar, S. 2012. Evolutionary meta-analysis of association studies reveals ancient constraints affecting disease marker discovery. Molecular Biology and Evolution 29: 2087–94. doi: 10.1093/molbev/mss079.
We find that the current approaches show a propensity for discovering disease-associated SNPs (dSNPs) at conserved genomic positions because the effect size (odds ratio) and allelic P value of genetic association of an SNP relates strongly to the evolutionary conservation of their genomic position.
Ralph, P. & Coop, G. 2013. The geography of recent genetic ancestry across Europe. PLoS Biology 11: e1001555. doi: 10.1371/journal.pbio.1001555.
We find that a pair of modern Europeans living in neighboring populations share around 2–12 genetic common ancestors from the last 1,500 years, and upwards of 100 genetic ancestors from the previous 1,000 years.
