If you've participated in the Sorenson Molecular Genealogy Foundation’s (SMGF) DNA study, you may be able to get your genetic genealogy test results for just $19.50.

SMGF’s collaboration with the DNA-enabled social networking site Genetree has provided an avenue for SMGF to release the DNA profiles in what study director Scott Woodward calls a “compelling, confidential” way.

To be eligible for the offer, you must have ordered an SMGF participation kit prior to Oct. 23, 2007, and returned the properly completed kit to SMGF postmarked no later than Dec. 31, 2007.

If that’s you, you’ll be able to access your mitochondrial (mt) DNA profile (with genetic information passed from mothers to their children), along with the pedigree information you submitted to SMGF, online through Genetree.

You’ll need a free Genetree basic membership to view your profile. It’ll take about two weeks for your request to be filled—get instructions for obtaining your results on Genetree's "unlock" page.

The SMGF study started in 2000 at Brigham Young University’s Center for Molecular Genealogy, with researchers collecting blood samples and pedigree charts at genealogy conferences. The goal? Build a database of DNA and corresponding genealogical information.

Several years ago, the project outgrew the university and moved to SMGF, where the database now contains nearly 100,000 DNA samples and more than 6 million corresponding genealogical records from people in 170 countries.

You can search SMGF databases and contact potential relatives through the site, but until now, participants didn’t receive their test results.

On Genetree, which launched in beta last October, you can create profiles for yourself and deceased relatives, add DNA test results or order an mtDNA test ($99 or $149), search for relatives, share memories, build a family tree, and invite relatives and friends to participate.
