Shared Samples

The 1000 Genomes Project shares some samples with the International HapMap Collection. The Family Relationships listed above includes those samples that were also part of the HapMap Project which can be found here.

Population Description

These cell lines and DNA samples were prepared from blood samples collected in the Southwest USA from individuals who identified themselves primarily as African-American. All parents in the trios and duos, and all the unrelated individuals identified themselves as having four African-American grandparents who were born in the same general area of the Southwest USA.

Referring to Populations

It is important to include a reference to "Southwest USA" when describing the source of these samples in articles or presentations. Including the area of the United States where these samples were collected reinforces the point that the sample set, while not genetically "atypical", does not necessarily represent all African-American people in the United States, whose population history is complex. The population should not be described as "African American" out of respect for the expressed wishes of the donor community. It also should not be described "African".

The full population descriptor is African Ancestry in Southwest USA. The shorthand label is African Ancestry SW and the abbreviation is ASW.

It may be scientifically appropriate to pool data from these samples with data from other ancestrally related groups, when the data show that the groups have similar allele frequencies. If the groups all have primarily African ancestry, the designation "African ancestry" (abbreviation: AFA) to describe the combined analysis panel is recommended. If only groups very closely related to this group of African ancestry individuals have similar allele frequencies, then another abbreviation may need to be used.

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