DYS710 Micro-Alleles
|
The DYS710 marker is a high frequency mutating YSTR that is very useful for near range (family) genealogy studies. Many alleles carry a N.2 micro-allele which further increases the variability of this marker. I just have fixed the bug in Ymatch which prevented entering the micro-allele, so you are able now to store the allele with- or without a microallele in your DNA-Fingerprint account.
Here is a frequency distribution chart for the first 142 results.
The marker can be ordered from Family Tree DNA in the advanced orders panel.

Working Draft of the Y Chromosome Tree Below R-M269
|
This draft shows a portion of the Y chromosome tree in extension to Karafet et al. [1] and the ISOGG tree [2]
I have added the recently discovered SNP markers and I implemented the topology from our latest evaluation runs. Some positions on the tree are only verified by single samples. Additionally I have marked the uncertain assignments which are either work in progress or which cannot be tested by our laboratory due to missing control samples. More information on the SNP details can also be found at Ymap [3].
Note that because I'm frequently updating the tree you may need to refresh the web page to see the latest version. Most browsers cache the graphics from the first visit.

Many thanks to all voluntary participants of the genealogical testing community for sharing their testing data from deCODEme and 23andMe chips and some of them providing control samples for my evaluation test runs. Special thanks also to David Reynolds who sketched out the first draft at DNA-Forums and helped me to refine the topology by cross checking all sources. This work wouldn't have been possible without the great spreadsheets from Ann Turner and Adriano Squecco who collected the SNP data and made them available to the public.

Website Functionality Restored
|
After my web server provider has switched from PHP4 to PHP5 in July users had problems to log in and new users couldn't even register. It took me a while of work to find out the actual reasons. It turned out that the SESSION variable wasn't properly stored and I had to call
register_shutdown_function('session_write_close');
in Postnuke's includes/pnsession.php (right after ini_set('session.auto_start', 1);)
in order to get it working. Thanks to TiMax
Now the login and register functions should work again. Sorry for the inconvenience and thanks for your patience.

Y Chromosome Browser
|
Dear genealogists,
During my current work on Y chromosome markers I frequently ran into the question where exactly those markers are located. The location of the markers is often the key to understand the recombination mechanisms and if multiple markers are aligned to the same reference sequence we find out that markers with different names may in fact be one and the same location on the Y chromosome.
Looking up marker positions in public databases has been time consuming and needs a lot of knowledge in molecular biology. For this reason I have collected information about all kind of Y chromosome markers and their positions along the current HUGO reference sequence. To make this all accessible to the public I have arranged the data in a HapMap style genome browser and we have setup a webserver at Family Tree DNA so that it can be accessed at a high speed internet connection.
The web address is easy to remember:
http://ymap.ftdna.com
Note that there is no www in the URL!
The browser usage is very simple:
Just type in a marker name into the Landmark or Region field and submit the Search. Examples: M201, DYS456, or a region like Yq11.221
The browser will show the position of the marker in the Overview graphic and it will zoom at the propitiate range in the Details view. If you zoom out a little bit, you will see the markers in the neighboring region. The marker of interest will be highlighted in yellow so that you don't loose its position. If you click on the marker it will display more detailed information and sometimes a link to more external resources like NCBI or GDB. The numbering of the reference DNA sequence is exactly synchronized with other ressources like the UCSC genome browser (Human March 2006 http://genome.ucsc.edu/)
The Y chromosome browser is still under development, so essential features and markers are still missing, but I thought that it is already very helpful for the advanced DNA genealogist and I didn't want you to wait much longer before you can try it. The database already contains more than 40.000 features and it will be updated frequently. I believe that some specialist genealogists out there may find errors and missing features. We intend to make the browser as complete as possible, so please send all requests to my e-mail address: thomas@familytreedna.com . Thanks for your help and have fun exploring the Y chromosome!

DNA Transfer DNAFP to FTDNA
|
Dear DNA-Fingerprint Customers,
I just wanted to mention that Astrid is currently in Germany and this is the last good and easy opportunity to transfer your DNA from DNA-FP to FTDNA. Astrid will fly back on Saturday this week (May 5th 2007).
So if you want to transfer your DNA to the Houston lab and didn't indicate this before, please log in into your DNAFP account and choose FTDNA-Transfer from the Main Menu. On Friday when Astrid has packed her luggage we will remove the automatic transfer option from the website. The transfer will be then much more complicated for us, so please be considerate and use this last opportunity.
For those who don't want to transfer the extracted DNA will be simply stored in Germany as promised at -20 C in a regular freezer, but we can't guarantee 100% uninterrupted frozen storage in case of a failure of the freezer because we can't fix it so quickly from here in Houston. So we recommend the storage in the automatized REMP SSS storage in Houston (see www.remp.com) for everybody who wants his DNA in a safe place.
Thomas Krahn
May 4th. 2006: The transfer form is now closed.

New Search Engine For Autosomal Markers: Amatch
|
Please note that I have now setup a search engine for autosomal STR markers and CCR5. It is accessible from the main menu under the name Amatch. If you don't want that your autosomal alleles are searchable by the public, please switch your account to be not viewable by the public or setup an account just for the autosomal markers which you can protect for your privacy.
The new geographical mapping interface is functional now at Amatch, Xmatch, Ymatch and MTmatch. The maps don't reflect the reality because not enough users have updated their country of origin information, yet. So please, whenever you have time for it, please update your country information.
All alignment and blast functions should be available and functional now for mtDNA. The https secure webserver still needs to be configured on the new platform. I hope to be able to follow up on this in the next weeks.

Happy New Year!
|
Happy new year to all DNA-Genealogists! The DNA-Fingerprint website has successfully been transferred to the provider Variomedia.de . The most important functions are working, but there are still many bugs to resolve. The userpages and the YMatch/XMatch/MtMatch databases are working, but the Excel- and Blast functionallity still needs to be configured. Please report all bugs, so that I can fix them. I'm working on it and I'm trying my best allthough I don't have a high speed internet connection in Germany anymore!

Merry Christmas!
|
We wish all DNA genealogists a peaceful and nice holiday season! We're looking forward to a great new year with many new scientific projects which we want to realize together with Family Tree DNA in Houston next year. The DNA Fingerprint website needs to be transferred to a German provider, because until now it was running on my own physical web server in our house. We will not continue our DSL connection, so the web page will be installed on a server platform of a commercial web hosing company. This means that the access will be much quicker in the future, but there may be some bugs and quirks to fix while installing on the new platform. So we can't exclude a possible downtime of the website for several days. In any case we promise to be back online as soon as possible in January 2007. Happy new year!
Astrid and Thomas

Online Form For Transfer Of Sample And Results to FTDNA
|
We have created an online form for submitting DNA and results to our new laboratory in Houston. DNA Fingerprint customers can transfer their DNA sample to Family Tree DNA and save the money for the transfer from the U of A which takes longer and is more complicated. If you want to merge your results and transfer your DNA sample you must log in into your account and select FTDNA transfer from the main menu.
Please be patient. We need to check every transfer manually for consistency. So the data may only show up several weeks later at FTDNA. For technical reasons we can now only transfer the results for full FTDNA panels to the existing FTDNA database. Once this is upgraded to a new database format we are able to include the remaining markers.
