As the costs of sequencing our DNA shrink and the roles of digital media in our lives expand, we will need to understand who (or what) controls the ownership, access and use of our genomic information.
From state regulation to Google to Facebook, who controls the acquisition, transmission and replication of our genomic information and material will become an important battle in the 21st century. Read more »

As I’m doing my PhD in clinical genomics, I’m really interested in the connection between the Internet and medicine. I was happy when Pathway Genomics, one of the newest direct-to-consumer genetic companies, offered me a free genetic test.
After an interview I did with them, I sent my saliva sample back and 3-4 weeks later, I received an email that my results were ready. This is my experience and the things I found interesting. As I got a free test from Navigenics a year ago, I plan to compare these services. I was very interested in the service of Pathway Genomics because of what they analyze:
1) Sampling: It was quite an easy process with only a few papers to fill (though it’s always hard to solve FedEX issues from Europe) and clear instructions. A video about a patient showing the whole process in 1-2 minutes, including saliva collection and filling out the paperwork, would be useful.
2) Preparations: I liked that I had to complete a questionnaire focusing on my lifestyle and patient history (Your Environment and Lifestyle, The Shape You’re In, and You and Your Family). As family history is the best genetic test out there, so it’s important to use that data while analyzing genetic results. Though, I couldn’t calculate my BMI (couldn’t use kg and centimeter) and the family history application wasn’t working for me. Read more »

A little over two years ago, I confessed that I was “just a little scared of genetic testing.” I have two young children and almost every day I see traits in them that I’m pretty sure they inherited from me whether via genes or behavior. If you’re a parent, I’m sure you can imagine that there’s a lot of self-blame going on in our house.
So when it comes to genetic testing, I should want to know but I don’t. At least not right this minute. Haven’t I got enough to worry about?

Genetic testing is all the rage. Thousands of tests are now available over the Internet, costing people anything from $60 to $3000 per test. While some DNA sequences are fairly well understood (like the BrCA gene or the chromosomal anomaly that causes Down’s Syndrome), most of them are only loosely associated with specific diseases and health outcomes. Experts agree that one day we’ll have a better understanding of the complex interplay of multiple gene sequences, but that day is still far off.
A recent post at GigaOM (h/t to KevinMD ) was critical of genetic testing in general, noting its potentially prohibitively expensive consequences:
Somewhere between 10 and 50 percent of autopsies reveal diseases other than the one that killed the patient. If consumers test themselves, then tell their doctors, the medical system could wind up treating 50 percent more diseases than it does today — even those that wouldn’t have killed the patient.
I interviewed Dr. Joanne Armstrong, senior medical director for Aetna, and assistant professor of obstetrics and gynecology at Baylor College of Medicine in Houston, Texas, about the current state of genetic testing. To listen to the full conversation, please click here.
Dr. Val: First of all, could you tell me a little bit about your work, and what got you interested in genetics in the first place?
Dr. Armstrong: I am the head of the Women’s Health division of Aetna, and about 8 years ago when BrCA testing (the test for predisposition to breast and ovarian cancer) became widely available, I began thinking about the educational initiatives that needed to support this testing. I knew that it would become part of mainstream medical practice and wanted to make sure that patients understood the tests and what to do about them.
Dr. Val: In your view, what are some legitimate and appropriate genetic tests?
Dr. Armstrong: There are about 1200 genetic tests available now, and most of them are not medically appropriate or clinically valid. Read more »
It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
Book Review: Is Empathy Learned By Faking It Till It’s Real?
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
The Spirit Of The Place: Samuel Shem’s New Book May Depress You
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
Eat To Save Your Life: Another Half-True Diet Book
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
