Population Description

Principal Investigators for Community Engagement and Sample Collection:
Houcan Zhang, Beijing Normal University, Beijing, China
Changqing Zeng, Beijing Genomics Institute, Beijing, China

These cell lines and DNA samples were prepared from blood samples collected from individuals living in the residential community at Beijing Normal University. All of the samples are from unrelated individuals who identified themselves as having at least three out of four Han Chinese grandparents.

It is important to include a reference to "Beijing, China" when describing the source of these samples (and to use the abbreviation "CHB" where a shorthand designation is needed). While residents of the Beijing Normal University come from many different parts of China, and while the samples are in no way genetically "atypical", they were not necessarily drawn to be representative of all Han Chinese people, nor of all people in China, where there are 56 officially recognized ethnicities. The population should not be described merely as "Asian" or as "East Asian", terms that encompass many populations whose ancestors came from places other than China.

After the complete descriptor "Han Chinese in Beijing, China" has been provided, it is acceptable to use the shorthand label "Han Chinese" or the abbreviation "CHB" in the remainder of the article or presentation. However, the full descriptor for each population should be provided before the shorthand labels are used; this will help to avoid the risks associated with over-generalization of findings.

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 East Asian ancestry, the designation "East Asian ancestry" (abbreviation: EAA) to describe the combined analysis panel is recommended. If only groups very closely related to the Han Chinese have similar allele frequencies, then another abbreviation may need to be used.
