Did you buy one of these ancestry DNA tests? Were your results what you expected based on what you know about your family history? Take our poll and let us know: https://t.co/RB0KFMsFCo https://t.co/stL3i2YVqZ

Good morning! Here it is... hot off the press. Well... sort of.😎
My latest for @cbcmarketplace.
We put top selling DNA ancestry kits to the test.
What can your spit really tell you?
Just how accurate are they ?

For everyone asking.... no we did NOT plan this !
catch the full @cbcmarketplace investigation into DNA ancestry kits tonight at 8pm ET.

New from @cbcmarketplace: Twins get some 'mystifying' results when they put 5 ancestry DNA kits to the test @CBCharlsie
|January 18, 2019 at 10:30AM||@cbcmarketplace|
Ancestry DNA kits are growing in popularity, so we decided to test the tests, and learned the results aren't 100 per cent accurate. https://t.co/mhiKeS2bGA @CBCharlsie

Have you ever bought or been tempted to buy one of those ancestry DNA kits? Here’s why the results you receive aren’t 100 per cent accurate. https://t.co/mhiKeSjMy8 https://t.co/lD39WfGBI0

Sharing my personal DNA story to help educate consumers on what your spit can and can't say about who you are and where you come from.
With a little help. @SNCarlyAgro puts on her investigative journo hat for this one.

Marketplace investigates the science and marketing behind popular DNA Ancestry kits. Just how accurate are they? Charlsie Agro tests 5 top brands... and we’re sending in the saliva of her identical twin sister, Carly Agro, too.

@skmonckton It looks like the bioinformatics prof quoted (Mark Gerstein) in the article is on Twitter. I wonder if he could shed some more light on where he suspects the variance arose from? @MarkGerstein
|January 18, 2019 at 10:18AM||@Ibycter|
@skmonckton @MarkGerstein Aside from wet lab issues, these companies likely have similar analysis and pattern-matching strategies, so likely there would be several points along the pipeline where minor variance could be introduced. Any suspicions where?
|January 18, 2019 at 11:24AM||@edyong209|
"Despite having virtually identical DNA, the twins did not receive matching results from any of the [five genetic ancestry] companies." https://t.co/Q916EAOYN8
|January 18, 2019 at 11:41AM||@Maikel_Boot|
Great video by @MarkGerstein's group (here at @Yale) in the article as well. They compared the DNA sequences and concluded that the ancestry should have been identical.

big takeaways from this week's @cbcmarketplace investigation into DNA ancestry kits:
🧬remember, these are statistical estimates.
🧬have some fun, but don't take your results to heart.
🧬your results may change!
🧬we're actually a lot more alike than we are different.

While he can't say for certain what accounts for the difference, Gerstein suspects it has to do with the algorithms each company uses to crunch the DNA data. "The story has to be the calculation. The way these calculations are run are different." https://t.co/RuSwBjUcg1
|January 19, 2019 at 01:22PM||@tmpear|
This doesn’t exactly inspire confidence in commercial DNA ancestry kits.
|January 19, 2019 at 01:38PM||@LeighGTurner|
"Usually in science we have a process like peer review & make the data accessible, & make the algorithms accessible, that's how we ensure the high quality of the data. In this case, we don't have access to that because the companies keep the data private." https://t.co/T7AGI1LHFR

Probability is a mathematical concept NOT a scientific truth! Wrongly applied in too many situation for self interest with misleading results. Twins get some 'mystifying' results when they put 5 DNA ancestry kits to the test

At home kits are still a fun novelty but their results should be taken with a grain of salt https://t.co/0iO6R8F050 #genomics #23andme #ancestry

Another reason to avoid giving your DNA to online testing sites: the results may be far from accurate! “Twins get some 'mystifying' results when they put 5 DNA ancestry kits to the tests.” https://t.co/8El9CsGJjV

Identical twins, different ancestry profiles |"The biggest DNA ancestry companies have tested millions of people..despite [their] popularity, there is absolutely no government or professional oversight of the industry to ensure the validity of the results"

“Identical” twins with #DNA 99.6% the same, receive widely varying results from all 5 DNA ancestry analysis companies tested

#DNA #test tells with statistical accuracy which continent your ancestors came from, not which country or town. Really? Why bother! Twins get some 'mystifying' results when tested with 5 DNA ancestry kits. #genetics https://t.co/kdiJhcfoGP

What happens when identical twins get DNA ancestry testing? Not only did the 5 companies used give different results, but 23andme found different ancestries for the two twins--with identical DNA: https://t.co/HjotcrIBUm

@Ibycter @skmonckton @gamzeandgursoy @MarkGerstein They do let you export your data for testing on other platforms.
I’ve had two done from DNA to analysis for comparison (Ancestry and Nat. Geo.). Results were very comparable with differences likely related to different analysis objectives for the two organizations.
|January 20, 2019 at 10:47AM||@docdez|
@Ibycter @skmonckton @gamzeandgursoy @MarkGerstein I’ve also exported data to run my own analyses via third parties. Ditto.
Notably, also, recent DNA predictions very closely match my family oral and written history (Mennonite diaspora). And likely relative hits match individuals who claim shared ancestors with me.
|January 20, 2019 at 10:49AM||@docdez|
@Ibycter @skmonckton @gamzeandgursoy @MarkGerstein That said, most people won’t have the training to play around with the data or understand the statistical nuance, so it’s easy to see how there can be confusion.
