I Tried a Bunch of DNA Tests and All we Got Was a Bunch of Useless Data

As a immature child, any morning during morning we would arise adult to daub dance on a square outward my mom’s bedroom door, many to my bad mom’s chagrin. These morning salutations became an quick family story, as did my robe of removing adult with a sun. Imagine my surprise, then, when a DNA exam recently suggested that we am, in fact, a night owl.

This personal discernment came to me around SlumberType, a new DNA investigate “app” that looks during 10 opposite genetic variants compared with nap in sequence to indication your genetic chronotype, or, as a association puts it, “where we tumble along a spectrum of ‘morningness’ to ‘eveningness.’” SlumberType is one of some-more than a dozen new DNA products in a new DNA “app store” recently launched by a consumer genetic contrast startup Helix. The apps, that rest on DNA sequencing regulation a user purchases from Helix, operation in purpose from a simply interesting to those dictated to assisting people sleep, eat and practice better. But as we competence imagine, a tip to a good night’s nap is a tiny some-more difficult than DNA alone.

The thought behind SlumberType, Ron Andrews, a CEO of a primogenitor company, Exploragen, told me, is to assistance people get a improved night’s nap by bargain what genetics competence contend about their healthy tendencies. The company’s scientists combed by dozens of studies on sleep, and chose genetic variants many strongly compared with nap to build a regulation for displaying people’s particular chronotypes. Andrews pronounced his exam helped him comprehend that he’s a “bee,” (a morning person) and adjust his nap patterns accordingly. My possess regulation had suggested we am during a distant finish of a spectrum, my arise activity hours descending in a diminutive hours of a night. we am typing these words, by a way, during 5:00 a.m., after descending defunct during my laptop operative during a oh-so-late hour of 9:00 p.m.


In a past decade, DNA sequencing has gotten really, unequivocally cheap, paving a proceed for an assault of direct-to-consumer genetic contrast companies that effect to offer a answers to all from what booze we competence like to a form of practice optimized for your body.

Typically consumer DNA tests need that we separate in a tube, send your separate into a lab, and a few weeks after get behind a one-time report. Helix, though, has a opposite vision. For an initial price of $80, a association sequences what’s famous as a exome, a 20,000 or so many critical genes of a tellurian genome. It’s a distant some-more endless exam than a genotyping companies like 23andMe and Ancestry.com perform. Customers can afterwards collect and select what pieces of information they competence like from their genome, purchasing third-party DNA apps from a Helix store. These apps embody those labeled “entertainment,” like Insitome’s stock app designed to establish what commission of your DNA is from Neanderthals. It includes health apps from partners like a Mayo Clinic to assistance surprise people what genetic diseases they competence carry. And it includes app advising people on lifestyle choices like practice and nutrition, a difficulty of contrast that has perceived a many critique from scientists. The thought is that business will lapse to a DNA app store again and again via their lives.

I’ve previously reported on a pseudoscientific inlet of many lifestyle DNA tests. The grounds simply inspires skepticism—a elementary separate exam that tells we how to best live your life? Many tests rest on possibly deficient science, or an deficient bargain of how many your genetics describe to who we are.


But we was still curious—could we reap something useful from these tests, something I’d never considered? I tested out a handful of DNA wellness apps from Helix’s app store, as good as from Orig3n, another consumer genetic contrast association that offers lifestyle DNA tests. On a whole, we found myself besieged by so many (often conflicting) information that it was tough to make any clarity of what it unequivocally meant. I was sold on a promises of “unlocking a whole new turn of information,” for a “truly personalized” proceed to my health, yet what we unbarred instead was a data-driven headache.

One gene in Orig3n’s Bliss exam confirmed that we am indeed a morning person, calming me that SlumberType had been wrong. Other tests contradicted contribution we know to be true, such as a exam that told me we have naturally high levels of B12; progressing this year, we started holding vitamin B supplements after a blood exam during my doctor’s bureau suggested my levels of vitamin B were intensely low. Individual tests also seemed to infrequently protest themselves, as did a exam that sensitive me we was both not during risk for plumpness (hooray!) and disposed to plumpness (damn) formed on opposite genes.

One genetic variant suggested we competence have reduce levels of a bad kind of cholesterol. Another indicated “higher cholesterol levels than a endorsed levels.” One exam pronounced we metabolized caffeine and ethanol normally. Another pronounced we was quick to metabolize caffeine and delayed to metabolize alcohol. While there seemed to be no agreement on either we can ambience sourness in food, my ambience buds assure me that we can.

In 2008, an European Journal of Human Genetics article suggested that direct-to-consumer genetic tests are mostly tiny improved than horoscopes that tell people information they were already compliant to believe. Like a horoscope, we found myself nodding along to information that already fit into my pre-conceived thought of self, and tossing aside anything that didn’t.


“Most of this things is bogus,” Eric Topol, a geneticist during Scripps Research Institute, told me as he corkscrew by Helix’s DNA app store on a other finish of a line. “I can find frequency any scholarship that backs many of this up. It’s going to give genomics a bad name.”

There are copiousness of explanations for a inconstancies we found in my tests. In some cases, a scholarship was simply shaky, formed on studies that were too small, too few or too slight to extrapolate for a ubiquitous population. When it comes to nutrition, several experts told me that there is simply not adequate investigate to behind adult a infancy of a many “nutrigenomics” tests now on a market. (There are a few exceptions. For example, a genomics behind genes that outcome in lactose dogmatism are well-studied.) Different tests demeanour during opposite genes to tell we a same square of information. And methods of interpretation vary. SlumberType, for example, built an algorithmic indication of my chronotype formed on several genetic variants. Orig3n, on a other hand, simply tells users about all of a particular genes they have and what any various competence mean, that is since some of a regulation seemed contradictory.

The other join is that we are, of course, some-more than a sum of a genetic parts—my bent towards morning is formed on some-more than usually a As, Ts, Cs and Gs that contain my DNA code. Children and aged people generally arise early; teenagers stay adult late during night. Gender, diet, ethnicity, practice and other environmental factors can all play a role.


“I’ve been disturbed for many years that in a open sermon there is this summary that we are a DNA,” UC Berkeley geneticist Rasmus Nielsen told me. “The biggest problem is that this things is marketed as actionable and there is no justification of that. If they’re offered lizard oil, it’s since of this substantial explain that we can somehow urge your health.”

Test that give consumers information about illness contingency go by a FDA capitulation process, yet differently consumer genetic contrast has so distant evaded regulatory approval. The biggest risk in removing a genetic palm reading is expected to your bank account. But critics prove out other discouraging possibilities. For one, a flourishing marketplace of pseudoscientific tests competence give consumers a disagreement of genetics.

The remoteness we give adult when giving out your genetic information is a concern—a justice of law could enforce companies to palm over your DNA. And, as all genetic contrast companies prove out in their excellent print, while a Genetic Information Non-Discrimination Act protects opposite health insurers requesting your genetic data, it does not forestall providers of life, incapacity or long-term caring word from doing so when a exam has already been done.


Nielsen also told me tests doling out aptness and dietary recommendation could breeze adult enlivening people to adopt lifestyle habits that are not unequivocally right for them. Many tests advise that users find out a recommendation of a alloy before creation lifestyle changes, yet mostly it’s in a excellent print, or somewhere equally easy to miss.

Even if a information is useful, some studies have suggested consumers don’t indeed change their behavior formed on genetic tests anyway.

“It’s tough to know if these tests are protected yet meaningful how people are unequivocally regulating them,” pronounced Neilsen. “In general, we have to ask if it’s unequivocally good to have some-more information if we don’t unequivocally have a skills to use that information?”

For me, application was a biggest adhering point. we had a torrent of information about my health and fitness, yet there were so many information points we had no thought how to make clarity of them. Some regulation were intriguing, such as a idea that a deleted GSTM1 gene means we need to eat some-more cruciferous vegetables to assistance my physique make adult for a lacking enzyme that helps with detoxification. Most of a time, though, a information usually wasn’t useful.


This isn’t to contend there are no genetic tests that are worthwhile. Tests like that for a BRCA gene, for example, can assistance a lady make critical decisions about her possess health, and parents-to-be mostly advantage from anticipating out either they are carriers for critical genetic disorders.

“Some of these things have value,” pronounced Topol, indicating to a patrimonial cancer exam set to entrance in a Helix marketplace soon. “But cholesterol, we don’t need a genetic exam for that. It doesn’t matter if we have a gene variant. Either we have high cholesterol or we don’t.”

Robert Green, a Harvard geneticist and confidant to Helix, told me that while he doesn’t consider any DNA app on a marketplace is useful or scientifically valid, he does consider that a blast of a consumer genomics marketplace will assistance to teach consumers and eventually to democratize DNA.


“There is a tragedy between building on legitimate scholarship and selling things that wandering so distant from a scholarship or prove lifestyle application that hasn’t been proven,” he told me. “There is an blast going on in personalized genomics and it’s not going to delayed down. we don’t consider we can stop it, so we consider we have to start going in a other direction.”

Green pronounced he anticipates a margin being disorderly for a while. In a end, though, he sees lifestyle products like those Helix and Orig3n offer as “relatively submissive ways to start training about genetics.”


James Lu, co-founder and arch scholarship officer of Helix, was upfront about a stipulations of what his company’s genetic contrast can tell you.

“Historically there has been this viewpoint that DNA is this book of all answers, a Magic 8 ball, per se,” he said. “Science has definitely proven that’s untrue.”

His hope, though, is that as a margin progresses, a apps in a Helix app store will be means to do a improved pursuit contextualizing information to assistance consumers make clarity of what all that information means.


“We’re going to have to combine DNA and other information together to yield finish answers,” he said. “It’s still a early days. we consider a lot of a problems we see in a margin will solve themselves.”

Some of a products we attempted did give me useful information about how to review my results. DNAFit offers several aptness and nourishment products by a Helix app store. When we get your results, before divulgence them a association guides we to a page that explains “everything about who we are is comprised of a communication between dual factors — how we are innate (our genetics), and what we do (our sourroundings and lifestyle).” Understanding your genetics, it says, can assistance we to change a second partial and grasp a happier, healthier you.

In a end, though, information is usually profitable if we can make clarity of it.

DNAFit’s fine-print reveals something that reads closer to a truth: “Genetic Information is theme to poignant limitations”; “some of a interpretations that we yield competence not be applicable”;”“Genetic Information reported has not been clinically validated.”


In a end, what use did training we have genes that prove we am a night owl unequivocally do? My genes are partial of who we am. But who we am is not a night owl, no matter what any DNA exam competence say.
