Regional Ancestry by Insitome

Shill alert!

When readers and friends found out I was going to work with Spencer Wells, many asked about ancestry analysis. By and large I said “wait.”

Wait no longer. This is now a 3 day pre-sale promotion for our Regional Ancestry product. Basically, you can get it for $19.99. I wrote a blog post on the product, Ancestry as a window onto your past.

The customers who have already purchased Neanderthal and Metabolism will probably get their results first, because remember that Helix apps reuse the original data sequenced and typed. Those who have already gotten previous results on any Helix app will be able to get results almost immediately when the app is live (the constraint here is compute time).

Currently, we are projecting the appl to be live starting January 8th, 2018 (being conservative).

Also, at $19.99 this is a great way to get into the Helix ecosystem.

(note the current ancestry product is autosomal analysis. no Y and mtDNA)

Reify my genes!


In the comments below Antonio pointed me to this working paper, What Do DNA Ancestry Tests Reveal About Americans’ Identity? Examining Public Opinion on Race and Genomics. I am perhaps being a bit dull but I can’t figure where its latest version is found online (I stumbled upon what looks like another working paper version on one of the authors’ websites). Here’s the abstract:

Genomics research will soon have a deep impact on many aspects of our lives, but its political implications and associations remain undeveloped. Our broad goal in this research project is to analyze what Americans are learning about genomic science, and how they are responding to this new and potentially fraught technology.

We pursue that goal here by focusing on one arena of the genomics revolution — its relationship to racial and ethnic identity. Genomic ancestry testing may either blur racial boundaries by showing them to be indistinct or mixed, or reify racial boundaries by revealing ancestral homogeneity or pointing toward a particular geographic area or group as likely forebears. Some tests, or some contexts, may permit both outcomes. In parallel fashion, genomic information about race ...

Analyzing ancestry with ADMIXTURE, step by step

Over the past few months I was hoping more people would start doing what Zack Ajmal, Dienekes, and David, have been doing. There are public data sets, and open source software, so that anyone with nerdy inclination can explore their own questions out of curiosity. That way you can see the power and the limitations of  genomics on your own desktop. I wonder if one of the biggest reasons that more people haven’t started doing this is formatting. It can be a pain to convert matrix formatted files into pedigree format, for example. But the data gusher isn’t ending, look at what’s coming out (and has come out) in the 1000 Genomes project!

I’ve been thinking I need to write up a post which is a “soft landing” for people so that we can reduce the “activation energy” for this sort of thing…once you get hooked, you only go deeper. Luckily an anonymous tipster has sent me the link to a URL with a huge data set which has been merged, already pedigree formatted. Here are the populations:
