Population Description

These cell lines and DNA samples were prepared from blood samples collected from individuals living in the community of Xishuangbanna Health School of Xishuangbanna, Yunnan, China. All of the samples are from unrelated (50 female and 52 male) individuals who identified themselves as having four Dai Chinese grandparents.

Referring to Populations

It is important to include a reference to “Xishuangbanna” when describing the source of these samples (and to use the abbreviation “CDX” where a shorthand designation is needed). These samples were not necessarily drawn to be representative of all Dai 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.

The full population descriptor is Dai Chinese in Xishuangbanna. The shorthand label is Dai Chinese and the abbreviation is CDX.

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 all the groups have East Asian ancestry, the recommended designation to describe the combined analysis panel is “East Asian ancestry” (abbreviation: EAA). Another abbreviation may need to be used for groups very closely related to the Dai Chinese with similar allele frequencies.

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