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 from people living in Los Angeles, California who identified themselves as having at least three out of four grandparents who were born in Mexico. Note that the individuals whose samples are included in this set are different from those who provided samples for the "Mexican-American" panels included in the NIGMS Human Genetic Cell Repository, even though both sets of samples were collected in Los Angeles.
Referring to Populations
It is important to refer to this community as "Mexican Ancestry in Los Angeles, CA, USA" when describing these samples in articles or presentations. Including the full name reinforces the point that the sample set does not represent all people with Mexican ancestry in the United States, nor all Mexican people, whose population history is complex. The population should not be described as "Mexican American" out of respect for the expressed wishes of the donor community. The population also should not be described merely as "Hispanic" or "Latino", since those designations encompass many communities.
The full population descriptor is Mexican Ancestry in Los Angeles, CA, USA and the abbreviation is MXL.
Additional guidance about how to refer to the populations can be found at Guidelines for Referring to the Populations in Publications and Presentations.
