Population Description
Principal Investigator for Community Engagement and Sample Collection:
Richard Sharp, Baylor College of Medicine, Houston, TX
These cell lines and DNA samples were prepared from blood samples collected in the Houston, Texas metropolitan area. All of the samples are from unrelated individuals who identified themselves as Gujarati and reported having at least three out of four Gujarati grandparents. "Gujarati" is a general term used to describe people who trace their ancestry to the region of Gujarat, located in the northwestern part of the Indian subcontinent, and who speak the Gujarati language. However, no attempt was made to clarify the meaning that donors attributed to their self-reported Gujarati identity.
It is important to include a reference to "Houston, Texas" when describing the source of these samples (and to use the abbreviation "GIH" where a shorthand designation is needed). The sample set, while in no way genetically "atypical", does not necessarily represent all Gujarati people, whose population history is complex. The population should not be described merely as "Indian" or "South Asian Indian", since those designators encompasses many populations with many different geographic ancestries.
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 Asian ancestry, the designation "Asian ancestry" (abbreviation: ASA) to describe the combined analysis panel is recommended. If only groups very closely related to the Gujarati have similar allele frequencies, then another abbreviation may need to be used.
