Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

Should You Get Your Genome Sequenced?

By Mark Sisson

Genetic Disease ConceptEarlier this year, I explored the “evolution” of human dietary requirements in the last 10,000 years by examining some of the SNPs – single nucleotide polymorphisms, or variations in genetic sequences – that relate to diet and nutrition. I concluded that while certain genetic changes to the way we process certain foods have arisen in certain populations, for the most part we’re still best off eating from an ancestral, Primal spread of animals, sea creatures, and plant life. Nothing has changed on that front in my mind, but people are still understandably curious about their genetic predispositions toward various conditions, and, with the recent reduction in price for SNP sequencing from 23andMe (to $99 with no subscriptions required), as well as slightly more affordable full-on genome sequencing (~$1000) on the not so distant horizon, it’s easier than ever to actually do it.

But should you?

I definitely don’t think everyone should do it. It’s the least expensive it’s ever been, but there are other factors to consider before making your choice and taking the plunge.

The stress of “knowing.”

What if you were to do it and the results came back showing you carried the allele for an increased risk of heart attack? Would you go on statins? Would you change your diet? Would you freak out and bounce from veganism to Primal to fruitarian? You might not even change anything about your lifestyle, continuing to eat healthy and exercise regularly and get plenty of sleep only, but with the addition of a nice helping of useless stress to go along with it and complicate matters. And the added stress can make the threat of disease even higher.

Laymen misinterpreting data.

“The gene for” is a scary phrase that’s permeated our culture. We worry about the gene for breast cancer, the gene for Alzheimer’s, the gene for baldness, and so on, but the reality of genetics is much more complex. Most of us aren’t equipped to evaluate the data we get from these services, and trying to do so may get us into trouble.

An excess of data and paucity of interpretation.

We know a good amount, but the field of personal genomics is still in its infancy. What if you come up with a particular SNP that has successfully predicted a disease in several studies – you’re gonna get that disease, right? No. In all those studies that showed a connection, not every single person with that SNP got the disease. There could be other, unknown alleles that interact with the original “bad” SNP, countering it and rendering it null. There could be lifestyle factors that affect the expression of the gene variant, intensifying or negating it. We just don’t know yet. And in case you thought we just need more data to get it right, getting more elaborate sequencing may confuse things even more, at least until the experts are better versed in analyzing the results.

Inaccurate results.

They’re still working out the kinks on this stuff, as one journalist who tried out several different competing genome sequencing services and got wildly varying results discovered. Or how when Razib Khan, a huge proponent of 23andMe and other sequencing services, used the ancestry feature set and found out that while he was 40% Asian, his daughter was only 8% Asian. He was able to adjust the parameters and get it figured out, but the average consumer may be misled.

That said, it’s true that the more people get sequenced, the more data the experts will have to draw on and learn from. Thus, doing it could help “the greater good,” if you care about that sort of thing. I actually think that’s a legit reason to get the sequencing if you’re going to do it, but it may not be enough to justify it in your eyes (and wallet).

If you’re a chronic worrier, a person who assumes the worst and runs to Google whenever you get an odd symptom (remember, everything’s cancer on Google), use caution. Sequencing your genome or getting an SNP analysis could ease your worry and show you that you’ve got nothing going on, or it could kick start your mania and make things even worse. If you thought Primal blogs and message boards get unnecessarily arcane, check out the level of analysis on personal genome sites! I was tempted to write “overanalysis” back there, but did not, because the complexities of genome research are such that detailed analysis is often required rather than overkill. And that’s my point: if you don’t have the time for it – if you’ve already got a busy schedule and heaping more work on top of it would only add stress – it’s probably not worth it.

If you’re the curious sort, a person who wants to know how much Neanderthal blood you’ve got and whether your earwax is moist or dry, go for it. You’ll likely find some interesting data to play around with. If you can afford it, you’ll probably be glad you got sequenced.

If you’re already doing everything right, wowing the doctors with your health markers, losing weight if you have some to lose, improving in the gym, and generally just feeling fantastic, you probably don’t need it. You might learn a few things, but it won’t all of a sudden invalidate your current healthy habits.

If you’re the type who needs a kick in the pants to get going and get healthy, if you’ve been lagging and feeling crummy, if you need the fear of the genome to get you moving in the right direction, getting sequenced might be worth it. 

Gene expression is still king. Just because you got your results back and have the SNP “for” a particular condition doesn’t mean you’re going to get it. You might be more likely to get it provided you engage in certain behaviors. However, many of these behaviors are things you are already (or should be) avoiding: sitting inside watching TV all day, eating processed refined food for all your meals, eating food fried in rancid seed oils, failing to exercise or move your body on a daily basis, being socially isolated, never experiencing nature, failing to use your brain, and rarely laughing or smiling. Sure, a few genetic states might conflict with the general Primal advice:

  • Like a sunlight allergy; if you’re allergic to the sun, you’ll know it because it might feel like “hot wax” on your bare skin.
  • Folks with hereditary hemochromatosis may absorb and store excessive amounts of iron, which can increase inflammation and lead to various illnesses. Testing ferritin levels, giving blood and limiting dietary iron – or consuming iron-chelating coffee, tea, and red wine with iron-rich foods – are good moves for people concerned about hemochromatosis.
  • Some people carry an allele that impairs their ability to utilize and convert folic acid, but that just means you should be getting your folate from leafy greens and organ meats rather than folic acid supplements – which you should be doing anyway.

Overall, I like the potential of genetic sequencing, but it’s not quite there yet. Family history trumps genetic data, at least for now. Ask Grandma about her parents and parents’ parents, look at old family photos, explore causes of death for your relatives – these will give you a nice general picture of the state of your genetic susceptibility to various diseases. It’s not as “exact” as genome sequencing, but it’s much easier to analyze.

In the end, whatever your genome has to say about you, the basics are always going to work out. Eating plants and animals, walking a lot, lifting heavy stuff, sprinting, and all the other usual Primal Blueprint advice is never going out of style. For that reason, I’m not very interested in getting my genome or SNPs sequenced. Over the course of almost sixty years, I’ve got a pretty good handle on what makes me tick, what makes me feel like crap, and what makes me healthy, happy, strong, fit, productive, and energetic. If, for argument’s sake, I discovered that whatever I’m currently doing to feel all those awesome things would somehow negatively interact with a random gene mutation, I still wouldn’t change a thing.

But I sure as heck might worry more.

Thanks for reading, folks. I’d love to hear from you, now. Have you had your genetics sequenced? Are you interested?

I actually want to get my husband’s genome sequenced before we have kids. He’s adopted so we know absolutely nothing about his family medical history. I’d really like to know what kinds of things to keep an eye out for from our possible offspring (and for his possible health as he ages).

I agree this is a dangerous walk to take. My mom’s also adopted and knows nothing of her medical history. What if she had found out her possible predispositions before having us? Would she have skipped having kids after seeing some of the things that manifested? Knowing my mom, I have a feeling she would have been very miserable without the four kids she has, despite the health issues that have arisen. What if you find out about a predisposition to something awful – are you going to forgo children? Would you really be ok with that? Or, are you… Read more »

I think your behavior and diet have a much bigger impact on your health than your DNA does. Pretty much every male in my family is bald. When I was 20 my hair started falling out at a faster rate and I began freaking out. First I tried rogain and then moved to propecia. The propecia worked and stopped my hair from falling out and I maintained at that level of hair. About a year ago when I went back on paleo I decided to stop taking the propecia mainly because I was lazy and forgot to go to the… Read more »

My aunt died of cancer. There were enough irregularities in her case that she was offered free gene sequencing so they could research it some more. She refused, because there is currently nothing in US law that says an insurance company would not be able to use that data in determining her daughters’ eligibility and rates for medical insurance.

This is a very well-balanced article. I’m a genetic counselor and get a lot of questions about sequencing or SNP testing. It is so important that people educate themselves and not oversimplify the information. Genetics is so complex and much of the data received from this test cannot be fully understood. Genetic counselors can be very helpful to put things in perspective. Also, the “$1000 genome” will be raw data. Making sense of the data will cost quite a bit more in the near future while we are still trying to make sense of it. That being said, I would… Read more »

I am a science writer and biology teacher, and I’ve had a lot to say on this subject in the recent past.

However, I and most of my family got the 23andMe kit when it first came out.

I don’t plan on taking anything to heart. One thing I’ve learned in the last couple of years is don’t put a lot of faith into anything you read or numbers you might see. One thing Primal has taught me is that our genes are not our destiny. I won’t become full blown diabetic as long as I stay Primal. I caught it. I stopped the progress – at least down my direct line (probably will be no kids anyway). And since health insurance is being forced on us – no worries there either.

They have no guidance, no support. Read their posts and ask if you want to go there. . . ask your spouse, parents & children. Because when you test yourself, you are also testing a part of them.

I’ve done it, had a discount code and had it done when it was $99 (before it went up then came back down) so only paid $50. I find this stuff very interesting, but don’t worry too much about it. I figure if I have a 5% chance of getting something, that means I have a 95% of not, so odds are still in my favor. The ancestry bit was really interesting, and the Neanderthal especially. At 2.9% I’m pretty up there.

I think a big exception would be people with known or suspected Ashkenazi ancestry, or other certain ethnic groups with high levels of Autosomal recessive diseases such as Cajuns or Amish. I had some known and some suspected Ashkenazi ancestry, 23andme made it clear how much I had and which autosomal recessive diseases I carried (not many, none serious). You used to have to fret about this and go to a genetic counselor to get the final say. If I had found I carried Tay Sachs I would definitely take a different approach to child-bearing.

I understand the point of view but I have to respectfully disagree. Especially with the $99 pricing from 23andMe, any information that educates a consumer is a step in the right direction. Too many people rely on a broken symptom care system and do not take charge of their own health. While in its infancy, your results should not change so you can always look at your SNPs with the current algorithm.

Of course, this information is best used in conjuction with a pertinent family health history and consulting with a knowledgeable doc about how to approach any mutations that may be bothersome.

No junk either, or flour products or white sugar, sticky. But i have 2 bowls of rice a day, no bread etc.

There is nothing wrong with being vegetarian, as look at Mark Sisson’s son. He is vegetarian and is as healthy as Mr. Sisson. What I’ve learned over the years, is that we are a diverse species, many cultures and tribes from all over the world have different diets. Meat-heavy eaters like the Inuit, or plant-heavy eaters like the Polynesians. They are all very, very healthy but with just different ratios of food. If you really want to know what to eat, look into your ancestry, I’m a northern European and I’ve looked into a meat-heavy diet.

It’s a testament to the flexibility of our stomachs. However, “reasonably healthy” doesn’t mean ideal or even thriving. The Polynesians live in the tropics and have far less stressors to deal with than the Intuits. (Polynesians also have a predisosition to become very overweight.)

Heather

I think it works both ways, if you had your DNA sequenced you would not change a thing and you take care of your health. I think that if people knew what they were pre-disposed to (do a short family medical history and you can at least have a guess) people would not change their behaviour. In fact, even when people do get diagnosed behaviour is difficult to change.

I think the key element here for some people is increased worry…I would certainly stress more knowing my unexpected genetic predispositions.

http://www.personalgenomes.org/ It is not a question of “the” test, there are only a few common mutations in specific genes that are correlated well enough with disease to be worth testing. What’s far more interesting is the effect that a person’s collection of variants may have on gene regulation, and what sorts of degenerative or spontaneous conditions this might predispose them to. Joining a project like the PGP (Personal Genome Project) addresses both the need for larger sample sizes in evaluating genetic associations, and potentially decoding certain epigenetic aspects that interface the genome and transcriptome. The amount of data being generated… Read more »

I had some genetic testing done for health issues, was told I needed to eat a low fat, low protien, high carb diet. Which I tried and felt terrible on. Around that time, I found paleo/primal and decided that since I felt better on it, I would continue on it. 6 months later I got a letter from the genetics lab saying due to new research, the category I fell into should eat low carb, not high carb. Do what your guts tell you is right, nobody else

Annalee, what gene site told you to eat a low carb diet — couldn’t of been 23andme.com — If there is a site out there that you can upload your raw data and get that info, would be interesting.

My wife and I did 23andMe to prior to having kids just to check for shared carrier genes.

On that front, our kids would be very safe from any disease.

But I came out with a hugely increased chance of DVTs. This actually got my doctor to write a note for a sit/stand desk at my work which is awesome.

With the knowledge I gained from 23andMe it was that much more motivation to adopt primal living.

I’m hoping to get an official diagnosis for a mental disorder then live the rest of my life thriving on a disability pension.

I’m coming in a little late here – I recently purchased a kit and received my results from 23andme and I’m not sorry I did it. As stated, there are lots of holes to be filled, however what it did tell me is very accurate. Much of the health I know about myself. I didn’t learn anything shocking or that I’m dwelling on, and I also know that while I may not be susceptible to certain diseases, it doesn’t mean that I’m free and clear of those diseases should I live my life in a way that would cause a… Read more »
