Population Description

These cell lines and DNA samples were prepared from blood samples collected in Bangladesh. The samples are from a mix of parent- adult child trios and unrelated individuals who identified themselves as Bengali. All individuals identified themselves as having four Bengali grandparents.

It is important to include a reference to "Bangladesh" 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 Bengali people, whose population history is complex. The population should not be described merely as "South Asian" or "Bangladeshi", since both of those designators encompasses many populations with different geographic ancestries.

After the complete descriptor "Bengali in Bangladesh" has been provided, it is acceptable to use the shorthand label "Bengali" or the abbreviation "BEB" 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 Bengali 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.
