Razib recently mentioned a paper on a polymorphism regulating memory in Drosophila. As I often do when studies like these are published, I determined the human homologue of the gene in question (PRKG1, in this case), and checked out the plots of summary statistics available online. Sure enough, there are peaks in the significance of iHS, Tajima's D, and Fay and Wu's H in the area (all signs of recent selection), though strikingly these peaks are only evident in the Asian population. Hm.
