EDIT 2/8/2014 – I am happy to report that the group originally organized by CeCe Moore is still planning to work on standards, guidelines, and certification for Genetic Genealogists, and thus I will continue to work with that group. Thank you to everyone that expressed support, and I will try to contact you soon.
Below, I’m taking the unenviable position of disagreeing, at least in part, with an editorial by Melinde Lutz Byrne and Thomas W. Jones in National Genealogical Society Quarterly entitled “DNA Standards.” (1) I’m writing to share my viewpoint and my thoughts about moving forward, and to provide a venue for continued discussion on the subject.
This is also the first post in a series of posts about “DNA and the Genealogical Proof Standard,” culminating with a presentation with the same title at SCGS Jamboree 2014 (on Friday June 7, 2014 at 2:30 PM).
In addition to many presentations on DNA Day (Thursday), there are DNA-related presentations planned throughout Jamboree (Friday through Saturday).
Browsing through the schedule (links at top of page here), these are the presentations I found either directed to DNA or explicitly utilizing DNA:
Blaine Bettinger (FR018) – “DNA and the Genealogical Proof Standard”
CeCe Moore (FR019) – “Why Should I Take a DNA Test?”
Nicka Smith, Angela Walton-Raji, Bernice Bennett and Shelly Murphy (FR024) – “The Future of African American Genealogy”
Bennett Greenspan (SA037) – “The Future of Genetic Genealogy”
ISOGG (SA049) – “Ask the Experts about DNA and Genealogy”
Maurice Gleeson (SU020) – “Ireland and the Slave Trade”
Drew Smith (SU024) – “DNA 102: Understanding and Using Test Results”
Blaine Bettinger (SU029) – “Begging for Spit”
My Other Presentations
I’m especially excited about presenting “DNA and the Genealogical Proof Standard.” This topic has not received nearly enough coverage by the genealogy community, and I think it’s very important. I will absolutely be asking for input from others, so feel free to share your thoughts below (or on a future post I’m planning). Here’s the short summary of the presentation:
Last year’s “Family History and DNA: Genetic Genealogy in 2013″ was the first of its kind and was a huge success As a result, the Jamboree organizers have organized a second DNA Day, which will held all day on Thursday, June 5, 2014, which is the day before Jamboree begins.
The keynote speaker at Family History and DNA: Genetic Genealogy in 2014 will be Dr. Maurice Gleeson, a popular speaker and the organizer of Genetic Genealogy Ireland 2013, Ireland’s first conference on genetic genealogy. I had the opportunity to speak with Dr. Gleeson at last year’s event (including about his interesting iCARA project), and he’s both engaging and extremely active in the genetic genealogy field. I have no doubt his presentations and keynote will be fascinating.
Following a trend inspired by discussions at the recent Conference for Family Tree DNA Group Administrators, Family Tree DNA has released a new set of updates. This week’s update includes the ability to change the location for your most distant known maternal or paternal ancestors, and the ability to determine which of your Family Finder matches actually match each other. Although this functionality was previously available, it was cumbersome and was not accompanied by any visualization.
From Family Tree DNA:
Weekly Information Technology/Engineering Update (10 Dec 2013)
Matches Maps Locations Clear Button
Some users have requested the ability to clear their stored map coordinates for their most distant known maternal or paternal ancestors. We have added a Remove Location button to Step 3 of the Update Most Distant Ancestor’s Location wizard.
Yesterday, 23andMe provided an update on its blog (see “23andMe Provides An Update Regarding FDA’s Review”) about how it will respond to the FDA’s recent warning letter. In a nutshell, the company will continue to sell the same Personal Genome Service (“PGS”) kits, but new customers will only have access to ancestry-related genetic information and tools, and to their raw data. No health-related information will be provided, for now. Existing customers will continue to have access to all tools, including health-related information.
I’ll note that this is exactly what I predicted would happen in my blog post about the FDA warning letter (see “The FDA Orders 23andMe to Stop Marketing Medical Tests”). You heard it here first! It’s really the most logical approach while 23andMe communicates with the FDA.
You only have to go back about 5 generations to start losing ancestors from your Genetic Family Tree.
So many of the issues that newbies run into can be resolved or prevented through understanding of these concepts.
The Coop Lab
The lab of Graham Coop, an associate professor in the Department of Evolution and Ecology at UC Davis, maintains a blog where they often discuss genetics. Today they published an interesting blog post entitled “How much of your genome do you inherit from a particular ancestor? In the post, they perform a handful of different analyses using data they had for one generation of transmissions which was compounded over multiple generations.
In 1991, German tourists in the Alps discovered the mummified remains of a man who died approximately 5,000 years ago. Named Ötzi, the remains have been studied extensively and have revealed a wealth of information about life in this region.
Of note to genetic genealogists, Ötzi’s DNA has also been the subject of extensive analysis. In February 2012, sequencing of Ötzi’s full genome was announced (see here and here) which revealed, among other things, that the Iceman probably had brown eyes, belonged to blood group O, and was lactose intolerant. He may also have had Lyme disease, as the genome of the infectious agent Borrelia burgdorferi was also identified in the sequencing effort.
Ötzi’s Y-DNA belongs to a subclade of Haplogroup G defined by the SNPs M201, P287, P15, L223 and L91 (G-L91). As far as I know, he has not yet been typed for any of the subclades downstreaming from G-L91. More information can be found at the G-L91 page of the Haplogroup G Project, and elsewhere online.
There has been a great deal of coverage this week of the new patent issued to genetic testing company 23andMe. U.S. Pat No. 8,543,339 is entitled “Gamete donor selection based on genetic calculations” and is directed to methods for predicting traits for a child based on the DNA of candidate parents, and selecting a preferred donor based at least in part on the prediction.
Published today at MATTER is “Uprooted,” an in-depth look at genetic genealogy and DNA testing. The article contains numerous quotes from several names you’ll recognize, including CeCe Moore and me. Much of the story focuses on genealogist Cheryl Whittle and her roller-coaster quest to find her biological roots using DNA testing. From the preview of the roughly 10,000 word article:
“In Issue 11 of MATTER, award-winning writer Virginia Hughes tells Cheryl’s story, and describes how the twin revolutions of the internet and DNA testing have turned genealogy into a privacy minefield. After all, your genetic code is as personal as it gets — yet thanks to the web, you are no longer the only person who gets to control it.”
