{CEPH} with Northern and Western European ancestry] haplotypes available from the 1000 Genomes pilot phase) (1000 Genomes Project Consortium 2010) produces substantial increases in the number of loci that can be mapped, that it improves the fine resolution of genetic effects at individual loci, and that it provides particular improvements in association to SNPs with MAF > 5%. The full scale of the 1000 Genomes Project, which will sequence more than 2000 individuals, should further increase this gain in power (Li et al. 2010).
