Welcome to the Dodecad ancestry project!
The Dodecad ancestry project, named for the Greek word for "group of twelve", aims to provide detailed ancestry analysis, primarily for Eurasian individuals. Please read on, if you want to participate; if not, please subscribe to the feed to keep up with the project's progress.
The project was started by Dienekes' Anthropology Blog.
1) Project goals
The Dodecad ancestry project has two goals:
- To provide detailed ancestry analysis to individuals who have tested with 23andMe; other testing companies may be included in the future.
- To build samples of individuals for regions of the world (e.g. Greeks, Finns, Albanians, Southern Italians, etc.) currently under-represented in publicly available datasets.
I neither endorse nor am I affiliated with any genetic testing company. I have chosen to base the project on 23andMe results, because (i) I perceive that quite a few people have used the service, (ii) the Illumina genotyping platform it uses has substantial overlap with the publicly available datasets on which my analysis depends.
2) Data privacy statement
Your raw genetic data will not be shared with anyone.
It will not be analyzed for anything other than ancestry or admixture. No analysis of physical or medical traits will be performed.
Individual-level results will be revealed with only a unique ID, without any further information about the identity or origin of each participant.
3) Who is eligible to participate
Due to my inability to process a large number of samples, at present, only the following groups are eligible to participate in the project's current pilot phase:
- Greeks (not necessarily from Greece: Cypriots, Pontic Greeks from the former USSR, North Epirotes, Griko speakers from Italy, Muslim rumca speakers from Turkey, etc. are all accepted)
- People from the Balkans
- People from Anatolia
- People from the Caucasus
- Non-Indo-European speakers from Europe (e.g., Finns, Hungarians, Basques)
- Scandinavians and Icelanders
- Jews from Italy, the Balkans, or Anatolia
Samples should be received by the end of October 2010. There may be a new opportunity to submit your data after that, which will be announced in this blog.
If you are uncertain whether your sample can be included in the project, please write to me at firstname.lastname@example.org to inquire.
Close relatives should not submit all their samples. If you and your relatives have tested, please submit independent samples. For example, if you have data for you, your father, and your mother, it is ok to submit either (i) your own data, or (ii) your father and mother's data -- provided that it is not a consanguineous (e.g., cousin or uncle-niece) marriage.
4) What to send
Your compressed genotype file from 23andMe and as much information about your ancestry as you wish to reveal. It is necessary, however, that you tell me at least the country of origin of most of your ancestors and their ethnicity. Information about spoken language, religion, may also be useful.
5) Where to send it
Send it to email@example.com. I will respond with a unique identifying code of the form DOD001, DOD002, and so on. The results will then be posted in the blog with that ID.
6) What you will receive
You will be included in an ADMIXTURE analysis together with other project participants and publically available populations, and the results will be published in this blog. Your sample will only be identified by your ID. If a group (e.g., Greeks) has at least 5 participants, I may also post the average admixture proportions for that group.
The following figure and table gives an idea of what to expect. Project members can expect to get a bar of their own, and a list of their ancestral proportions.
The number of components and population samples may vary over the course of the project.
7) Project updates
All project updates will be announced and presented in this blog. Additional commentary on the project may be posted in Dienekes' Anthropology Blog. I may also post occasionally on twitter about the project's progress.
I encourage feedback about the project from participants or prospective participants. Please address it to firstname.lastname@example.org
