23andMe genetic testing

on


 

 

 

 

 

Very long post today (3000 words) but you have the weekend to read it– and it’s worth reading.

A genetics researcher and director of the National Institutes of Health once said:

“Genetics loads the gun and environment pulls the trigger.”

I think a more meaningful quote comes from the bank robber character at the start of the 1971 Dirty Harry movie, who’s trying to figure out how many shots Clint Eastwood has fired from his revolver:

“Hey– I gots to know.”

 

23andMe background

I’m a tech geek, and I’ve followed startup companies for years. 23andMe came to my attention because a 23andMe co-founder is married to a Google co-founder, and nearly six years ago Google’s $3.9M early-stage investment in 23andMe was considered a controversial choice for Google’s venture funds. However 23andMe used the money to develop one of the industry’s fastest and most thorough automated analyses of genetic data. They quickly established their credibility by earning Time magazine’s 2008 “Invention of the Year” award.

Back then the company was charging as much as $499 to analyze sections of a customer’s genome, along with a monthly fee for access to their research and genealogy databases. It was an intriguing idea, but I’d also decided that decoding my genome was also way out of my price range. I was financially independent, but I didn’t get there by shelling out $499 for this sort of purchase. What would I do with the data?

23andMe eventually dropped the price to $299 to attract more customers, but I still didn’t see the value. Nearly 200,000 other people ponied up, however, so 23andMe’s databases grew large enough to be statistically significant. Researchers and specialists use the (anonymous) data to search for the genetic roots of many diseases. Pharmaceutical companies are also using the data to develop effective drugs and possibly even gene therapies. These corporate customers are willing to pay a lot more than $299, and rapid growth is financial catnip to a venture capitalist. Late last year 23andMe secured $50M in a venture round and announced their pursuit of a database of one million genomes. Shortly after they cashed that check, 23andMe accelerated their sales (and the growth of their database) by dropping the price to $99 with free lifetime membership.

$99?!? I can make room for that in our budget. Ironically the announcement came shortly after the start of the holiday shopping season, so we made it an ohana Nords present: the gift of self-awareness.

Like Dirty Harry’s bank robber, I’d suddenly found an intense personal reason for my curiosity. My father developed Alzheimers four years ago in his mid-70s and is currently deep into mid-stage symptoms in a care facility. (He’s doing well, but the disease’s progress is relentless.) His father lived until age 97 but spent his final 14 years(!) in a care facility under the vague 1980s diagnosis of “dementia”. My mother and her father both died in their 40s, so we’ll never know their genetic flaws. However my mother died of breast cancer and I wanted to know if I’d passed those genes on to my daughter. My spouse has a few questions about her own genealogy, and I’m pretty sure our daughter has wondered many times if she’s really related to the people who tried to raise her.

 

How it works

Each box contains a test tube, instructions, and the return shipping label.  You just add your spit.

23andMe boxes arrived in the mail

The process is straightforward: spit it out. Literally. You sign up on the company’s website, charge your credit card, and wait for the snail mail. A few days later a specially loaded test tube shows up in your mailbox and… you expectorate into it. (Only about 15 milliliters– one spitball.) It comes with directions (in an ambitious 14 languages and pictures) and plenty of helpful spitting advice. You seal the test tube, drop it in a plastic bag, and return the (postage pre-paid) box to 23andMe. After a couple of weeks they e-mail you the announcement that your data is on their website.

Fill it, cap it, bag it, and send it back in the box.

The spit tube with cap and preservative.

The actual analysis has been industrialized and automated.  Your spit ends up on a slide tray coated with nearly a million different copies of various genetic fragments.  When your genes match any of these fragments, a chemical reaction occurs to trigger a sensor on the slide.  A scanner reads the sensors and pulls the results out of the 23andMe database.

Better still, this is not “one and done”.  Samples can be saved for a very long time and sent back through the analysis.  As researchers find more interesting genes to analyze, bioengineers will improve the sensitivity of the chip and the number of genes it can detect.  All 23andMe does is provide more data to the researchers and pharmaceutical companies who are paying them for answers to specific questions, but a copy of your data is also uploaded on your account.

 

Psychological, ethical, and legal issues

Although genetic testing is “affordable” and the technique is established, the concept has incited an explosive ethical and legal debate. I doubt that the controversies will ever be resolved, but we have choices. I can’t presume to recommend how you should tap-dance your way through these minefields, but here are some issues to consider before you decide to get tested.

The first question is whether your awareness would actually lead to behavioral change. We all “know” that we’re supposed to eat healthy and exercise– how’s that workin’ for ya? Why in the world would we expect that our genetic data would inspire us to pursue an enlightened self-interest?

If you found out that you’re carrying genes which have a marginally statistical link to a fatal disease, would you change your habits? How far are you willing to go? Most heart attack survivors fail to make significant lifestyle changes (like quitting smoking) to improve their health and reduce their cardiac risk, so what makes you so sure you’d change your behavior? What statistical risk would cause you to change: 25%? 50%? 100%? A few women at high risk for breast cancer have opted for preemptive double mastectomies– what if your genes are linked to a 10-25% chance of breast cancer? If you’re at an elevated risk for prostate cancer… ouch, I don’t even want to think about it, and my Dad’s a prostate-cancer survivor.

Other questions: What if you learn that you’re adopted? What if the guy you’ve called “Dad” all your life learns that he’s not your biological father? If you’re carrying the genes for a serious disease, do you want to have kids? What if you decide to get tested but your spouse isn’t interested? If your unborn child turns out to have a genetic disease, would you choose an abortion?

Geneticist Bryan Sykes has documented dozens of situations in his books. What if your ancestry has a statistically significant percentage of other races in what you thought was a homogeneous family tree? What if your ancestors include both Thomas Jefferson and Sally Hemmings? What if you’re descended from Neanderthals? What if your culture’s creation beliefs might be more mystical than factual? What if you believe in the power of specific prayer for your own situation– or for others? These may seem like minor controversies if you’re not part of a the affected culture, but there’s been a huge uproar in many societies around the globe.

What about other risks? What if your genes keep your body from responding to certain chemotherapy drugs? What if you’re exceptionally sensitive to a drug, and a “normal” dose could kill you? What if you’re violently allergic to a food you’ve never tried? What if your college daughter turns out to be genetically slow to metabolize alcohol? Hey, I’m just reporting the news here, I don’t judge.

Could this affect you financially? If people learn about your genetic profile, how will they treat you? More importantly, how will your health insurer treat you? Can you still get life insurance? How much will you pay for long-term care insurance, if you can even get it? Will the insurance company insist on checking your genome for the longevity gene before they quote you a price on an annuity?

It turns out that your genome is legally protected by federal law against genetic discrimination in health insurance– and employment. Although there may be a statistical link between your genome and some diseases, that statistical link is not considered significant enough to affect health insurability (and certainly not employment). You can’t be turned down for health insurance because of your genome any more than you can be turned down for tobacco or alcohol consumption. However the law does not cover life insurance, disability insurance and long-term care insurance. The law may also be changed someday to allow different rates for different risks, and maybe an insurer could require genetic testing before setting those rates. Even if you’re protected by the full power of the law, do you really want to have to defend yourself through years of stress and costly litigation?

23andMe promises to keep your data private, but the Internet’s history is littered with the corpses of confidentiality vows. What if your genome is splashed across the Web, and on your Facebook profile? What if you’re blackmailed or humiliated or bullied because of your genome? This isn’t hypothetical or ancient history– you only have to glance at today’s headlines to read about ethnic atrocities. Even when the privacy controls work the way they’re supposed to, any data you make public could be compared to other public ancestry databases to personally identify you. And although 23andMe promises to keep your data private today, what if they get a court subpoena for a criminal investigation or a paternity suit? What if they just decide to change their policy and sell your data to the highest bidder? Oh, wait, they’re already doing that– although they promise to keep it anonymous. As far as you can tell.

Let’s bring this down to personal finance: if you have a 50% chance of developing a fatal disease in your 50s, then what’s your “safe” withdrawal rate? More importantly, when would you choose to retire? Would your spouse want to care for you when some horrible genetic event comes to pass? Would you abandon your family responsibilities and spend your 401(k) “experimenting” with “alternative lifestyles” while checking off your bucket list? If you have the fabled (and rare) “longevity gene”, then should you invest 100% of your portfolio in an inflation-adjusted annuity? Should you buy extra disability insurance? What about self-insuring for long-term care?

Enough questions. Luckily 23andMe has thought about this too. They’ve added checkpoints to their results that you have to acknowledge and unlock on your profile before you can learn the facts. When you review your data on their website, you have to click several confirmation windows to find out about genetic susceptibilities to diseases like Alzheimer’s. You have to specifically opt in to share your data, and frankly Facebook could learn a lot from 23andMe’s incremental privacy & sharing settings. You can’t actually delete your data from 23andMe’s servers and pretend that this never happened, but you can keep it as secret as today’s Internet tech can reasonably achieve.

Remember this: once you share, you can’t take it back. You can turn the feature on & off, but shared data can be copied and stored by the people you share it with. You cannot un-ring the bell.

 

What you get

23andMe organizes the results very well.  Once you unlock your main page, you can elect to unlock each of the subcateory summaries.  (Over 35 pages of printed summary alone, with hundreds more in the details.) Your personal web pages are broken down into dozens of categories with deeper links to background information, references, and other studies.  You can spend hours reading up on your “favorite subject”.  They compare your data to the averages and the statistics. You see all the research citations and you’re guided through some of the implications of the information. Once your genetic profile is in their database, they keep updating it with the results of new studies & data. You can answer survey questions and volunteer for research. Even better, those researchers and pharmaceutical companies will share their data as well, and you might be invited to join the FDA trials.  You can join 23andMe forums to discuss your genome with others who have a similar profile.  You can share your genetic data with anyone else who’s also a 23andMe customer.  (I shared mine with my spouse and my daughter.)  You can build your family tree and post it on 23andMe for their database to track down your distant cousins.

 

My results

Let’s cut to the chase:  Was it worth it?

Heck yeah.  Not only for me, but also for my spouse and our daughter.

In fact our daughter is even luckier to be alive than she’s already been told (many times). I should’ve paid for this even when it was $499. I should’ve mortgaged our home to pay for it.

If you’re closely related to me then I strongly recommend that you sign up for 23andMe and get tested. (If you’re one of my cousins, or if you’re even considering having kids with one of my cousins, then please have this done today. Seriously. Stop reading and go to 23andMe’s website now. If $99 seems too expensive then we need to discuss your budget priorities.) If you’re contemplating an intimate relationship with my daughter… well… you were already in for some interesting Q&A with her– and now it’s going to get even more focused. (Good luck with that.) Oh, and it turns out that she really is my daughter, to 85% certainty. Sorry, honey.

For everyone else, I’d suggest that the ethical minefields are not your biggest concern. You should worry whether you’re a ticking time bomb. Not just your own blissful ignorance– what if the “professionals” in your life are also ignorant or negligent? If you develop an exotic disease or cancer, you’re hoping that your doctor thinks to check your genome to find out if you’ll respond to a medication– or whether a “low dose” could kill you. If you’re even considering procreating then I think you owe it to your hypothetical life partner (and your hypothetical kids) to understand the risks you’re imposing on them.

Scary example: I’m a carrier of cystic fibrosis. Luckily my spouse had already decided that I’m done procreating (me, too, sorry ladies) and everything worked out fine, but I wish we’d known this info about, oh, 21 years ago. [Insert "dodging a bullet" metaphor here.] If we’d had this information before starting a family then we would’ve definitely opted for additional testing, and the results would’ve justified the minimal medical risks of the testing.

I’m also a carrier for hemochromatosis. I have a couple of susceptibilities for exotic chemotherapy medications that I hopefully won’t ever encounter, and I’m at nearly a 3x elevated risk of deep vein thrombosis. I have a marginally lower statistical risk for prostate cancer– but I’m still going to keep an eye on my PSA.

Since my daughter and I have shared our profiles, she knows which parent to blame for a host of minor issues. Nothing serious or heartbreaking, but definitely things that I wish I’d known at her age.

I was highly amused when my spouse’s ancestry turned out to be slightly above the global average of Neanderthal genes… until we learned that I’m much higher at 2.9% (the max is 4%). That just confirms the suspicions of many people in my military chain of command. (Sorry, XO, I really was born that way.)

My ancestry? 100% purebred free-range Scandinavian Viking on both sides. (I guess we could’ve seen that coming from my surname.)  Very few of my shipmates seem surprised.

My spouse’s genes? Well, no surprises there. The family longevity claims turned out to be fact. She’s already drafting her acceptance speech for our alma mater’s “Oldest Alumna” award. She assures me that she’s going to be around for a very long time… chronologically as well as relativistically. As for the rest of her genome, my relatives & friends would agree that I married up. Way up.

 

Alzheimer’s

Well, enough of the humor & snark. You regular readers of the blog are already wondering: “Hey, Nords, cough it out. Your grandfather died of dementia and your Dad has Alzheimer’s. Are you gonna get Alzheimer’s or not?!?

I clicked through all of 23andMe’s website acknowledgments and warnings to learn the results, but I’m not ready to share that info yet. When I do share it, I can’t change my mind and take it back.

Alzheimer’s Disease is estimated to have a 60%-80% chance of heritability, so 23andMe tests for the APOe4 variant (which may be the primary cause of Alzheimer’s). There’s another gene which may actually offer some protection, and 23andMe tests for that too. Based on those gene combinations, the probability of showing Alzheimer’s symptoms between the ages of 50-79 can swing from as low as 7% (the general Alzheimer’s population of that age group) to 44%. There may be other factors, but 23andMe doesn’t test for them.

The main reason I’m not sharing is because I don’t want you guys to treat me any differently than you already do. You don’t know whether I’m protected or at risk, and I’d rather be judged on the purported quality of my writing than on the documented quality of my genome. Neanderthal or not.

Besides, I doubt the Federal Long Term Care Insurance Program will lower anyone’s premiums based on 23andMe results. At least I’ll always have Tricare, and I no longer have to care about employment.

 

Would I do it again?

I’m glad I did the testing, and $99 is a compelling bargain for ensuring that I’m invested in the results. I’m happier knowing about it than being blissfully ignorant. Dirty Harry’s revolver could be loaded with more than one cartridge, but it still has empty cylinders. I stopped drinking two years ago, I don’t smoke, I take vitamins, and I’m not going to widen my horizons of any other illicit experiences. (Sorry, ladies.) My myosatellite cells and my mitochondrial metabolism may be spluttering and my recovery time sucks, but exercise and healthy eating are no longer hypothetical benefits: they’re preventive medicine. My chocolate-chip addiction is heading toward sugar-free and possibly abstinence. Those last 10 pounds? They’re outta here. Luckily paleo still favors bacon and cacao, so life remains worth living.

No psychological worries. I may be disgusted by aging, but I no longer fear it. There’s encouraging research into every dark corner of the human genome, and lab rats are being treated with experimental therapies, but human trials seem to be perpetually a decade away. It’s my job to be alive (and sentient) when the FDA puts out the call for trials volunteers.

This experience definitely checked my priorities. I’m not going to make any hasty lifestyle decisions but I sure am glad that I’m already financially independent. Whatever happens during however much time I have left, I’m especially grateful that I have not traded any of the last decade for corporate employment. I’m already insured for financial longevity by my military pension. Long-term care insurance is always a good idea whether your risk profile is at 1% or 99%, and we can also afford it. I’ll revisit that purchase when we’re in our 60s.

No matter what’s in my genetic revolver, I’d don’t want to miss my chance of a lifetime. When my spouse reaches our college’s oldest living alumna milestone, I want to be there with her as a reminder that there’s still one more alumnus who’s just a little bit older!

      Thanks, Judy– great article on how the field is going to have to address the issues.

      Interestingly enough, one of my family members has decided that they’d rather not have the analysis… even if someone else pays for it.

    Wow, Doug. This was enlightening. I haven’t heard of 23andMe before this. But as the father of two young children, I’m very interested in learning more about myself, and my health. I need to be around to take care of my girls!

    Reading this article also comes at a time when I am making a lot of small lifestyle changes – eating better, becoming more active, becoming more informed, etc. Small changes and constant personal growth are amazingly effective.

    Thanks for sharing.

      Those small changes add up, and this time I think they’re going to stay a part of my lifestyle.

    Thanks for the write up! I’ve had my eye on 23andme for a while, and always thought it was too expensive. Now that they’ve gotten rid of the monthly fee I am so tempted… after reading your post last night I was very close to ordering a kit.

    After thinking it through, I decided to continue to hold off, because for me this would really boil down to a source of entertainment more than anything. I will keep my eyes open for “sales” that the supposedly have occasionally though… I think they’ve had sales on “DNA Day” in April in past years?

    • Doug Nordman

      March 10, 2013 at 3:52 AM

      Thanks, Kudy! There’s a lot of entertainment, true, but you’ll also find out if you’re at an elevated genetic risk for a syndrome or a condition, or hypersensitive to foods or prescription drugs.

    Thanks Rob, it’s the best spending I’ve done all year!

    Mike, there’s enough information to keep you happily reading for hours. And if you’re a genealogy enthusiast like my spouse then you’ll keep going for months. “DNA USA” is a fascinating book, as is “Saxons, Vikings, & Celts”.

    You’re absolutely right about using the data to drive your behavior. That’s exactly how I felt when I read my results, and it’s the best motivation I’ve found in over 25 years. Even better, my daughter found our family’s info to be a tremendous relief and especially empowering– we can stop wondering, start planning, and keep an eye out for potential trouble.

    I’m heading down your path after coming from a different direction. Fitbits will be showing up in our house soon, as well as a few other tracking apps, because the habits only seem to change when you’re logging the behavior. But that’s a post or two for another day.

    As a data junkie, you know I’m doing this. I already track my steps, weight, exercise, food, financial status, and any number of other things daily, so I might as well add my genetic data! Nice post Nords! One of my favorites!

    VERY enlightening article, Doug. Thank you very much for being brave enough to share what you did.

    Has this experience changed your thinking about what you’d put into an advanced medical directive in case you get found on the beach flubbering after getting whacked in the head with your surfboard?

    • Doug Nordman

      March 8, 2013 at 5:37 AM

      Thanks, Jason! I have a few relatives who need to read this post too, and I didn’t want “fear of disclosure” to miss that sharing opportunity. Of course I’m going to be mightily annoyed if one of my elders says “Oh, yeah, we knew about that. Nobody told you?”

      My medical directive won’t have to change– it already advises not wasting any time resuscitating me. If there’s no hope for recovery then stop feeding me, unplug me, harvest the transplants, let the medical students carve on the rest, cremate whatever’s left over, and scatter me over the White Plains Beach surf break.

      I still remain confused on the Alzheimer’s caregiver dilemma. My Dad can’t form any new memories and he’s lost a lot of old ones, but he’s the happiest he’s ever been. His directive declines further heroic intervention (like chemotherapy if his myeloma returns) and I’d do the same thing if I was in that situation. But Alzheimer’s is much, much harder on the caregiver than on the patient. If I could no longer pass a mini-mental state exam then maybe it’d be kinder for all concerned to just let me paddle out a few more times to see if I remember how to find the beach again.

Comment? Question? What's on your mind?
