23andMe Updates

From the comments on my 23andMe posts:
Ann Turner asks:

Mark, if you or any of your readers are homozygous for the mutation conferring lactase persistence (both alleles are A), I’d like to compare notes on how far the homozygosity extends along the chromosome.

If this applies to you, leave a comment or send me an email and I’ll make sure Ann gets it.
Andrew Scheidecker posts:

If you can’t wait for 23andme to add support for raw data export, I’ve released the source code for a program that can extract the raw data from their website:


It can store the data in its own encrypted file format or export it to CSV.

I haven’t had the chance to try this program yet, but look forward to doing so soon.
Finally, Gary Wolf has an excellent post up on his experience with 23andMe so far. He ends his post:

But for now, I’m looking for ways to make my 23andme results more relevant. I welcome suggestions.

I’m in the same boat.


  1. can’t seem to get comments working on the excellent Gary Wolf article.
    Gary focus on the SNPs listed in Category:On_chip_Illumina_Human_Hap550 which is the chip used by 23andMe.
    And if Andrew’s Personal Genome Explorer works the way I hope, your 23andMe results are about to get a lot more interesting.

  2. I always suspected you were a homozygous.
    Sorry, too easy.

  3. http://snpedia.blogspot.com/2008/01/promethease-decodes-23andme.html. Does it make it ok if I say trackback? 😉

  4. Sweet, I will use this after I decode my genome.
