My 23andMe DNA Test Results - Post 1

I gave myself a 23andMe autosomal DNA test for Christmas, and sent the sample into 23andMe on 19 January 2013 (after finding where I had hidden the box).

Previosuly, I had tested my autosomal DNA with FamilyTreeDNA and AncestryDNA, my Y chromosome DNA with GeneBase, and my mitochondrial and Y-chromosome DNA with GeneTree (from the SMGF testing about 10 years ago).

I knew that I was in the R1b haplogroup from my previous Y chromosome tests, and in the K haplogroup from my previous mitochondrial DNA test.

I was notified that my 23andMe test results (all but the DNA Relatives matching) were available yesterday, and have been reviewing my health and medical risks and my ancestral results.  Here, in brief, are my test results:

1)  Autosomal Ancestry Composition (Map View):


Am I the "whitest" guy in the world?  99.3% European.  But only 11.5% British and Irish, 7.2% French and German, 1.5% Scandinavian, and 66.4% Nonspecific Northern European.

The above is the "Standard Estimate."  The "Speculative Estimate" is:


The speculative estimate is 43.0% British and Irish, 25.2% French and German, 2.7% Scandinavian, 26.1% Nonspecific Northern European, 0.4% Iberian, 1.2% Nonspecific Southern European, 0.7% Nonspecific European, and 0.6% Native American.

The intriguing part is the 0.6% East Asian and Native American, and the 0.1% Unassigned.  Huh?   Now that whets my research interest - where did that come from?  I need to know how many generations back that might be - I'm guessing in the 6th (128 ancestors) or 7th great-grandparents (256 ancestors).

My FamilyTreeDNA Family Finder results were:  89.15% Western European and 10.85% Middle Eastern.

My AncestryDNA results were 94% British Isles and 6% Uncertain.

2)  Autosomal DNA - Chromosome View:


That's pretty bland, isn't it?  All of that East Asian and Native American, and the 0.1% Unassigned, are on chromosome 12.  If I can find DNA Relatives with that same segment, it should narrow my search for those ancestors.

3)  Mitochondrial DNA Test:


So I'm K1b2b.

I did not know the sub-grouping of this from my GeneTree results - only that I was K.  So this is more definitive.  From what I know about my matrilineal line, it goes through English and Irish (perhaps Scots/Irish) families.  It will be interesting to see if I have mitochondrial DNA matches with somebody specific and not just "50 generations" back.

4)  Y Chromosome Test:



I'm R1b1b2a1a.  The only person identified as such on the list of Famous People is Malcolm Gladwell, so I'm in great company!

My GeneBase test results (20 markers) said I was haplogroup R.

My GeneTree (SMGF) test results (43 markers) said I was haplogroup R-M207, and subgroup R1b1b2a*-S128.

5)  My Neanderthal Ancestry:


I'm 2.9% Neanderthal ancestry, above the average Northern European percentage of 2.6%.  Some Facebook friends would say that accounts for my conservative political views...

When I get some DNA Relatives matches, I will report on them also.

I am struck by the seeming differences between the autosomal test results from 23andMe (11.5% British and Irish), Ancestry DNA (94% British Isles) and the FamilyTreeDNA Family Finder (89% Western European).  Why are they so different?  I guess they are not really that different, since my genealogical research shows that I have about 75% British Isles (almost all England) and about 25% Northern Europe (German, Dutch, French) ancestry in the 6th generation back.

This 23andMe test, which I paid $99 for on their special deal (still available, I believe!), was well worth the money.  In addition to the Health Overview material, I received a more refined mitochondrial DNA reading, a more refined Y chromosome DNA reading, and another autosomal DNA test with a better defined ancestry composition.

Have you compared the raw numbers, where available, between the various tests you've taken to see how they compare? I'd be interested to know how the Y-DNA test numbers of one company match up with another company's numbers. Ideally, they will be the same for the same markers, and only the refinement of the matching process is different and/or has changed over time. If the raw numbers are different, I'd be extremely curious as to an explanation for why they are different.

Randall,
I've thought about this, but it seems like the results fed back are sooo complex. Did you find the report "user friendly" or did you do lots of pre-search before finally ordering the test? I think $99 sounds pretty cheap, but I don't want to waste $$ on something I won't understand...thoughts?

Whoops, that comment was posted with the blogger acct that i nolonger use, so I would ask that you reply (if you do ) to my word press acct instead. Thanks again!

You got some interesting results. Technology that makes testing easier improves the quality of health care. This is the case all across the world, whether we are thinking of so called developed countries or other nations.

When people can get access to medical and DNA information quickly, they can make decisions about their health more speedily. In cases where it is hard to do a blood test or any other kind of medical check, individuals have to wait and battle with uncertainty. Developments that eliminate this are a move forward.

I know what we all are in my family. But I am Germanic and my wife is Malay. We know fairly well what we are. Though our kids are unique and we just want to see that in our genes. We want a record for future progeny as well. Combining our genes is just amazing.

How much did the whole package cost for 23andme? You had maternal tested. So that was $200 on top of the $100?

Also, if "DNA doesn't lie", why are the 3 different companies a little different in their results?

Finally, one person commented that you are African. That's funny. When I was in school, we did not com from Africa. In fact, I just looked it up yesterday, and does not make sense to me at all. Anyhow, I heard that all Europeans are 40% African and 20% Asian. Why didn't that show up in your test? Thank you for your time.
