Population Description

These cell lines and DNA samples were prepared from blood samples collected from individuals in Nigeria. All individuals identified themselves as having four Esan grandparents.

Referring to Populations

It is important to include a reference to “Nigeria” 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 Esan people, whose population history is complex. The population should not be described merely as “African”, “Sub-Saharan African”, “West African”, or “Sierra Leonian”, since each of those designators encompasses many populations with different geographic ancestries.

The full population descriptor is Esan in Nigeria. The shorthand label is Esan and the abbreviation is ESN.

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 African ancestry, then the recommended designation to describe the combined analysis panel is “African Ancestry” (abbreviation: AFA). If only groups very closely related to the Esan 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.
