This very interesting article on BBC News UK Magazine "Your DNA's in the post" discusses how the author spent about $985 bucks for the services of DeCodeMe, a company that provides an at home DNA analysis including risk factors for diseases, genetic traits, and ancestral background.
The author of the article discovered he has a higher than average risk factor for Crohn's disease.
"I scan the list of 25 traits again and settle on Crohn's disease. Here I'm told the research indicates that I have a lifetime risk 1.42 times the average."
Of course I already know I likely have the genetic marker for Crohn's and have tested positve for the Prometheus labs test. But it is an interesting idea to get my DNA tested. I would be very interested in getting my husband's tested as he knows very little about his Dad's side of the family. They are reportedly "Black Dutch" which no-one has much of an idea of what that actually means. It might mean a mixture of Native American, European, African American, etc. I think it would be very cool if my kids had Native American and African American genes. They are already a mix of 1/2 Jewish, 1/4 Korean, and that last 1/4 is the part we are not so sure about. Maybe "American Heinz 57 varieties?"
23andMe is another company that provides at home DNA analysis.
There is also this option from Family Tree DNA project where you can take part in a study of your surname.
