Population Description

These cell lines and DNA samples were prepared from blood samples collected in a small town near Florence in the Tuscany region of Italy. All of the samples are from unrelated individuals who identified themselves as having at least three out of four Toscani grandparents.

Referring to Populations

These samples, while not genetically atypical, do not necessarily represent all Toscani, nor all Italians, whose population history is complex. The population should not be described merely as "Italian", "Southern European", "European", or "Caucasian", since each of those designators encompasses many populations with many different geographic ancestries. Reference to these samples in the Italian language is preferred.

The full population descriptor is Toscani in Italia. The shorthand label is Toscani and the abbreviation is TSI.

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 European ancestry, the designation "European ancestry" (abbreviation: EUA) to describe the combined analysis panel is recommended. If only groups very closely related to the Toscani have similar allele frequencies, then another abbreviation may need to be used.

Members of the community where these samples were drawn developed a written statement that expresses their views about genetic variation research and their hopes about how their samples will be used.
