Personally, I am happy to participate in DNA research at 23andMe. Our collective data, used anonymously, can save lives.
Here's an article about what they are doing to find a cure for Parkinson's.
A 63-year old adoptee does the MyHeritage DNA test. Her initial match list includes an uncle and she is soon speaking to her 86-year old mother.
If your DNA is on My Heritage, your DNA match details are now consolidated into one place with different sections that will help you discover how the match may be related to you.
I like the way they do this. Read about it here.
If you have autosomal DNA test results from any of the major tests, you can upload your data for free to GEDmatch.
If you haven't done all the tests, you will probably pick up some new matches. If you have a family tree, upload your GEDCOM file too.
There are lots of powerful free tools for analyzing your data.

Here's a heartfelt story of a man who used DNA testing to ultimately identify his biological father.
He shares many good insights and demonstrates that persistence is important.
DNA testing of ancient skeletons can lead to surprises.
Here's another published DNA success story.
Published stories like this are just the tip of the iceberg. Most DNA-driven reunions are not covered by the media.
During the month of September (2017), Houston-based Family Tree DNA will be donating a portion of their sales to Hurricane Harvey disaster relief efforts.
If you have some additional testing to do or just want to stock up on test kits for later use, place your order now.
In case you're wondering, the FTDNA office and labs are fine. Flooded roads just kept the staff from getting to work for a few days.
Don't waste your money! I keep getting emails from companies selling DNA tests for skin care, supplements, weight loss, exercise etc. There is not enough science to support such claims.

Here's another DNA success story that reunites a man and both parents.
If you have DNA results from Family Finder, 23andMe or AncestryDNA, you can upload your raw data for free into the My Heritage DNA database.
This will yield new matches and another interpretation of your ethnic ancestry at zero cost.
I recommend that adoptees and any serious genealogists get into every database
An independent and ongoing review of the Helix DNA test by DNA Testing Adviser
Rob Warthen received an FGS technology award for his work on DNAGedcom. The site includes many innovative free tools for adoptees and genealogists working with DNA matches. Check it out.
About once a month I send out an email newsletter with a summary of recent news for genealogists and adoptees. You can sign up with just your email address. I don't need to know your name and I won't share your address with anyone.
For signing up, you get to download a free PDF file of my latest "Guide to DNA Testing." See this page on my web site:
You and another person have a certain amount of DNA in common, as reported by one of the autosomal DNA tests. So what is your likely relationship?
Blaine Bettinger's Shared cM Project--based on 25,000 user reports--has been updated. See averages, minimums and maximums for any measurable relationship.
Be sure to download the PDF for complete instructions on how to use the data.
Here's another reunion made possible by genetic genealogy DNA testing. Two brothers find their mother after 46 years.
If you did the health testing option at 23andMe, you may be interested in this VERY detailed discussion of 23andMe raw data in an Alzheimer's forum. I admit, I could not spend the time to read it all.
People from close-knit societies, such as Ashkenazi Jews and others, will get a lot more DNA matches on an autosomal DNA test than the typical user. Furthermore, those relationships will often be more distant than predicted.
To learn more about the concept of endogamy in DNA testing see this page on the ISOGG Wiki.
This blog post about single-segment autosomal DNA matches is six years old and I just stumbled on to it. While I don't pretend the follow all the math (feel free to skip), the basic conclusions seem sound and important today.
I had hoped that Amazon would let those who had already purchased my Guide to DNA Testing download the newer Kindle version for free. They won't. In fact, they won't even let you buy it.
If you have Version 2.0 of my Guide, you will want to see all the new and updated content in Version 3.0. Click this link for a free workaround.
How long does it take for an adoptee to go from DNA test results to speaking with her birth mother? In this case it was less than 48 hours.
The article says it was an AncestryDNA test; but the accompanying video shows a 23andMe test kit.
If an adoptee identifies a birth mother but she refuses contact, should he or she contact a sibling? That issue is discussed in detail in this great blog post by Lorraine Dusky. I agree with her completely.
If you're an adoptee or otherwise separated from biological family, the place to turn for advice and support is The DNA Detectives group on Facebook.
This article covers just a few of their many success stories.
Both the Internet and retail stores are now filling with DNA tests that make outrageous claims. Skin care? Weight loss? Pinpointing your ancestry to a specific village or tribe? Don't waste your money. On every page of my web site (in the left column) I now include a list of the only five DNA testing companies that I recommend.

To give every DNA tester personal control over their test results, AncestryDNA has made a number of changes in how multiple family members are managed.
This post on their blog will help you understand the new procedures for managing multiple kits.
One of the built-in features of the 23andMe DNA test is the ability to see which of your matches have overlapping segments. Blogger Jim Bartlett shares a step-by-step process for taking advantage of these Triangulated Groups.

We can't be serious all the time about DNA testing. Here is one writer's humorous look at the subject.
Using DNA tests with Jewish ancestry can be challenging because of endogamy. Briefly, there were lots of marriages within a close-knit society. The bride and groom often had ancestors in common.
That can make DNA matches appear to be closer than they really are. But there are still many successes as illustrated by this story
