Harappa Project New Site

As several people had asked, I have set up a separate website for the Harappa Ancestry Project at http://www.harappadna.org/.

I am keeping a link to the new site on the top menu bar here titled Harappa DNA.

I might also crosspost some items from the project here.

I have also set up a Facebook page for the Harappa Ancestry Project. Please like it on Facebook so I can get a nice short name for the Facebook page URL.

I have received several samples and will be reporting some analysis results soon. However, I do need lots of participants, so please spread the word.

Harappa Ancestry Project

I have become interested (some would say obsessed) with genetics recently. I wrote about getting my DNA test done and there’s a lot more about my own results that I plan to bore you with.

One fun application of genetic testing is inferring ancestry: Which ancestral group are you descended from? Can we estimate the admixture of the different population groups you are descended from?

Most DNA testing companies provide information about ancestry and genetic genealogy has taken off. With several genome databases (HapMap, HGDP, etc) and software (like plink, admixture, Structure) publicly available, the days of the genome bloggers are here. And I am trying to be the latest one.

In starting this project, I have been inspired by the Dodecad Ancestry Project by Dienekes Pontikos and Eurogenes Ancestry Project by David Wesolowski. The catalyst for this project was my friend Razib who I bug whenever I need to talk genetics.

What is Harappa Ancestry Project?
It is a project to analyze (autosomal) genetic data of participants of South Asian origin for the purpose of providing detailed ancestry information. So the focus of the project is on South Asians: Indians, Pakistanis, Bangladeshis and Sri Lankans.

The project will collect 23andme raw genetic data from participants to better understand the ancestry relationships of different South Asian ethnicities.

I have named it after Harappa, an archaeological site of the Indus Valley Civilization in Punjab, Pakistan.

People of South Asian origin, or from neighboring countries, are eligible to participate. The list of countries of origin I am accepting are as follows:

  • Afghanistan
  • Bangladesh
  • Bhutan
  • Burma
  • India
  • Iran
  • Maldives
  • Nepal
  • Pakistan
  • Sri Lanka
  • Tibet

Right now, I am only accepting raw data samples from people who have tested with 23andme.

Please do not send samples from close relatives. I define close relatives as 2nd cousins or closer. If you have data from yourself and your parents, it might be better to send the samples from your parents (assuming they are not related to each other) and not send your own sample.

If you are unsure if you are eligible to participate, please send me an email (harappa@zackvision.com) to inquire about it before sending off your raw data.

What to send?
Please send your All DNA raw data text file (zipped is better) downloaded from 23andme to harappa@zackvision.com along with ancestral background information about you and all four of your grandparents. Background information would include where they were born, mother tongue, caste/community to which they belonged, etc. Please provide as much ancestry information as possible and try to be specific. Do especially include information about any ancestry from outside South Asia.

Data Privacy
The raw genetic data and ancestry information that you send me will not be shared with anyone.

Your data will be used only for ancestry analysis. No analysis of physical or health/medical traits will be performed.

The individual ancestry analysis published on this blog will be done using an ID of the form HRPnnnn known to only you and me.

What do you get?
All results of ancestry analysis (individual and group) will be posted on this blog under the Harappa Ancestry Project category. This will include admixture analysis as well as clustering into population groups etc.

I suggest you read about Dienekes’ analysis on South Asians for an idea about what to expect.

You can access all blog posts related to this project from the Harappa Ancestry Project link on the navigation menu on every page of my website. You can also subscribe to the project feed.

Personal Genomics: DNA Test

Last year in April, 23andme were having a sale for DNA Day, selling their 550,000 SNP test with ancestry and health information for $99 instead of its regular price of $499 at that time. So I decided to take the plunge and sent my spit from the East coast to the West to be analyzed.

Then 23andme had another sale ($99 again but with the catch of a minimum of a year of $5/month subscription in addition), I got my wife and my sister to do it on 23andme’s new version 3 genotyping chip with more than a million SNPs.

I got my results in May 2010 and have been having fun with them since. So let’s take a look.

There are reports for your genetic risk of a bunch of diseases. Those are interesting and useful in some cases, but there is still a lot of work to be done in the area of genetic associations of diseases and for now except for a few important discoveries, family history is probably a better predictor of your disease risk than genetic testing. Oh yeah and there are a couple of scary-looking numbers in my reports.

The health reports also show carrier status and drug response.

In terms of other traits, it’s mostly information I already knew like:

  • I can taste bitter tastes
  • I have wet earwax
  • My eye color is brown
  • I have curlier than average hair

One thing that was a surprise was that I am likely to be lactose intolerant. It’s possible I am somewhat tolerant due to environmental reasons.

Since I wanted more analysis than the 23andme reports gave, I downloaded Promethease which is a freeware software which uses all the information at SNPedia to create a report about your SNPs and what features, traits and health factors are influenced by them. The report it generates is long and interesting, though not formatted very well.

PS. Yes, this is the sort of topic I alluded to in my return announcement.

While there is more navel-gazing coming (mostly about ancestry and genetics), there’s going to be posts of more general interest. Let me just go ahead and say that the friend Razib mentioned is me.
