Results: In this study we have sampled over 800 unrelated individuals from the population of Spain,
and have genotyped them with a genome-wide coverage. We have carried out linkage
disequilibrium, haplotype, population structure and copy-number variation (CNV) analyses, and
have compared these estimates of the Spanish population with existing data from similar efforts.
Conclusions:
In general, the Spanish population is similar to the Western and Northern Europeans,
but has a more diverse haplotypic structure. Moreover, the Spanish population is also largely
homogeneous within itself, although patterns of micro-structure may be able to predict locations of
origin from distant regions.
