Population Description

These cell lines and DNA samples were prepared from blood samples collected in the United Kingdom from individuals who identified themselves and their parents as Sri Lankan Tamil.

Referring to Populations

It is important to include a reference to the “U.K.” when describing the source of these samples. Including the name of the country where these samples were collected reinforces the point that the sample set, while not genetically atypical, does not necessarily represent all Tamil people, whose population history is complex. The population should not be described merely as “South Asian” or “Sri Lankan”, since both of those designators encompasses many populations with different geographic ancestries.

The full population descriptor is Sri Lankan Tamil in the U.K. The shorthand label is Tamil and the abbreviation is STU.

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 of the groups have South Asian ancestry, the designation "South Asian Ancestry" (abbreviation: SAA) to describe the combined analysis panel is recommended. If only groups very closely related to the Tamil 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.
