Dwelling DNA testing has gone from a curiosity to a aggressive market prior to now decade, with no less than a dozen firms now competing with trailblazers equivalent to Ancestry and 23andMe. However earlier than we examine and distinction the out there choices, let’s check out precisely why you’d spend money on a DNA testing service — together with the upsides and the caveats.
Providers out there
Should you’re utilizing a house DNA testing service, you are doubtless searching for certainly one of three issues:
Ancestry and household historical past: The primary huge draw of a full DNA check is that you will get an in depth breakdown on ancestry and ethnicity, and the migration patterns of your ancestors. Spoiler alert: Your ethnic background could also be radically completely different than you assume it’s.
Relative identification: Along with your permission, some DNA companies will allow you to join with relations you by no means knew you had — folks with matching DNA who’ve used the service and likewise given their permission to connect with doable relations.
Well being and illness information: DNA testing can even point out which circumstances for which you could have a preponderance. It is a controversial function, to make sure. Figuring out that you’ve a genetic predisposition to a sure type of most cancers could make you extra vigilant for testing, however it could additionally result in elevated stress — worrying a few potential situation that will by no means develop, even if you happen to’re “genetically prone” to it. The potential of false positives and false negatives abound — any such data needs to be mentioned together with your physician earlier than you act upon it.
How the assessments work
Afraid of needles and drawing blood? Excellent news: That is not a difficulty with these assessments. All you want to do is spit right into a vial or rub a swab in your mouth — all of the genetic information wanted for these assessments is current in your saliva — and ship it to the corporate for evaluation.
The rationale that saliva works in addition to blood (or hair follicles or pores and skin samples) is that your DNA — which is brief for deoxyribonucleic acid — is current in all of them. It is the essential genetic code current in your entire cells that makes up your key attributes, from the colour of your eyes to the form of your ears to how prone you might be to ldl cholesterol.
The important thing phrases you want to know when evaluating DNA testing companies are:
SNP (single nucleotide polymorphism): Genotyping is completed by measuring genetic variation. One of many extra frequent is SNP genotyping, which measures the variations of a single nucleotide polymorphism. In our service summaries under, we focus on the variety of SNPs. That is as a result of the extra an organization measures, the extra granular the variations analyzed.
Autosomal DNA testing: This check will be administered to each women and men, and traces lineage again by means of each the maternal and paternal bloodlines.
Y-DNA: The Y-DNA check can solely be administered to males, and traces DNA again by means of the patrilineal ancestry (principally from father to grandfather to nice grandfather).
mtDNA: The mtDNA is matrilineal and allows you to hint your ancestry again by means of your mom, grandmother and nice grandmother.
Autosomal assessments can get you high quality genetic data going again about 4 or 5 generations. As a result of the Y-DNA and mtDNA assessments are extra centered on one aspect of the road, you will get data going again farther, however with much less information about household construction.
four essential caveats
Earlier than you utilize any of the companies we have highlighted under, preserve these essential components in thoughts.
Match database dimension: Should you’re searching for household relations, that is essential. Merely put, the larger the pool of accessible information, the higher the possibility you will have of discovering a match.
Privateness issues: Nothing is extra non-public than your well being information, which is why you must be certain a potential DNA testing web site follows the identical best-practice on-line safety protocols you’d count on out of your financial institution or e mail supplier. You will need to search for two-factor authentication, an encrypted password database and so forth.
However for DNA testing suppliers, you must also examine how they’re sharing your genetic information — even when anonymously — and the way lengthy they preserve the info. It is not simply educational: Authorities not too long ago recognized a suspect within the Golden State Killer murders because of an open-source DNA and family tree service generally known as GEDmatch (not profiled right here).
Should you’re creeped out by how a lot data Fb, Google and Amazon have on you based mostly in your on-line searching habits, simply do not forget that these DNA testing companies are getting what’s successfully your medical historical past. Be sure of their insurance policies earlier than turning over that beneficial information. Additionally, even if you happen to do not share your DNA with a service, your familial DNA information could also be out there if a relative shared their genetic materials. The privateness points can get very advanced.
Do not count on excellent accuracy. They can provide you indications, however taking a DNA check will not magically produce a historical past e-book of your loved ones’s background.
Seek the advice of a health care provider on any well being information: Most cancers. Leukemia. Coronary heart illness. Alzheimer’s. There are a variety of scary afflictions on the market, and your DNA testing could properly point out which of them you might be genetically predispositioned to. However the information from DNA testing exists in isolation. It is best to seek the advice of your physician to discover the info from any of those assessments. They’re going to make it easier to decide methods to implement any way of life modifications or followup testing consequently, if it is price doing so.
With these explanations and caveats in place, we current to you 9 of one of the best DNA companies we have discovered. Some are higher than others, so you shouldn’t solely take our data under consideration when spending on a service, however search for evaluations and tales posted by those that have used the companies to see what their experiences have been.
