 Trios:  50
 Unrelated Individuals:  7


Population Description

These cell lines and DNA samples were prepared from blood samples collected from people living throughout the Spanish territory. The total number of geographical areas was 50, corresponding to the 50 administrative provinces (geographical areas surrounding a medium-large city) which constitute Spain, including the area in the Iberian Peninsula as well as the islands. Samples were collected from individuals who identified themselves as having been born in the area and having all four grandparents (two generations) born in the same area.

Referring to Populations

The full population descriptor is Iberian Populations in Spain and the abbreviation is IBS.

Additional guidance about how to refer to the populations can be found at Guidelines for Referring to the Populations in Publications and Presentations.
