Population Description

These cell lines and DNA samples were prepared from blood samples collected in the United Kingdom. The samples are primarily from unrelated individuals but include a small number of trios. All individuals identified themselves and their parent as Sri Lankan Tamil.

It is important to include a reference to the “UK” 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.

After the complete descriptor “Sri Lankan Tamil in the UK" has been provided, it is acceptable to use the shorthand label“Tamil” or the abbreviation “STU” 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 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.
