I'm forming a small study group of people with Dupuytren's contracture who have taken a test from 23andMe. This type of test looks at about 500,000 markers scattered across the entire genome. These markers would not be directly relevant for Dupuytren's, but they might reveal a common denominator.

A similar product, Family Finder from Family Tree DNA, could also be utilized.

One family study has implicated a region on chromosome 16. I think it might be possible for people to compare their results and confirm, rule out, or maybe even narrow down the chromosomal region where the mutation occurred. This thread tells a little bit more about my notion.

Please respond to me directly, DNACousins@aol.com, if you're interested.

Disclosure: I have a consulting arrangement with 23andMe, but the statements expressed above are my own and not official policy of 23andMe.

I bought the test offered by the National Geographic "Genographic" project, and allowed that data to go to Family Tree DNA, but I haven't purchased any additional products from Family Tree. Could I contribute anything to your study?

Sounds a little like a marketing effort to me. Please excuse if it is not!
