DNA testing is becoming more popular.
Taking a DNA test kit sounds like harmless fun but some people end up getting more than they bargained for.
DNA is a trove of personal information that can be hard to keep track of and protect.

Both Macron and Madonna have expressed concerns about genetic privacy. As DNA collection and sequencing becomes increasingly commonplace, what may seem paranoid may instead be prescient.
Many researchers are interested in the genetic history of the Khoe-San.
The South African Khoe-San communities are no strangers to exploitative research. One research team is trying to provide genetic ancestry results to community members. But they still face many challenges.

Many people are filing lawsuits after discovering that sperm banks failed to verify information from donors about their medical and personal backgrounds.
Direct-to-consumer genetic testing can help scientific researchers.
Scientists who work in local companies have acquired local knowledge and are therefore able to work with South Africa’s unique genetic diversity better than anyone else.
Individuals who upload their DNA test results to databases may not have much control over how it’s used.
Can the new owner of GEDmatch ,a genealogy database preserve its original purpose while allowing a seamless service to law enforcement?
Direct-to-consumer genetic tests are not an accurate source of health information. Users should also consider the future privacy implications of sharing their genetic data.
DNA testing kits will be a popular gift this holiday season. Before mailing off your saliva, it’s important to understand what these kits can and cannot tell us.
No, a DNA swab can’t tell you if you’re gay, or likely to be obese, or depressed. And it can be damaging to believe so.
Genetic apps claim to reveal fundamental insights about your health, well-being, and even intellect. But it’s not just spurious science - believing these traits are genetic can have harmful consequences.
More than 200 gene variants have been linked to outstanding sporting performance and this number could increase as we continue to research the link between genetics and athlete performance.
Genetic testing could help us build targeted and effective training routines for athletes, but the emerging science could also introduce opportunity for discrimination in the sporting world.
Scientists explain why commercial gene testing should be used with caution.
Is it worthwhile to know you’re 25% Irish?
We asked five experts if DNA testing was worthwhile. Four out of five said yes.

Genetic testing companies are offering tests that analyze the ends of your chromosomes – telomeres – to gauge your health and your real age. But is there scientific evidence to support such tests?
Polygenic risk scores currently account for only a small proportion of your total genetic risk.
Most common chronic diseases are the outcome of complex interactions between genetic, environmental and social risk factors, so a genetic risk score, on its own, isn’t much help.
If you’ve got the raw data, why not mine it for more info?
New research investigated who uses the wide array of tools available to people who’ve received their own raw genetic data and want to maximize what they learn from it.
We’ve underestimated the extent of mixing between ancestral groups throughout human history.
Estimating our ancestry is hard – because our backgrounds are much more mixed up than we thought. So don’t take your DNA ancestry test results literally: they’re just a prediction.
A woman uses a lancet on her finger to check her blood sugar level with a glucose meter.
Direct-to-consumer genetic testing company 23andMe is now offering a new ‘polygenic risk score’ that reveals your risk of developing Type 2 diabetes. Does it work? Are our family physicians ready?
Genetic ancestry testing might all seem like harmless fun, but there is a downside.
The results of genetic ancestry tests are grossly over-simplified. A new study shows the tests reinforce what you want to believe rather than offering objective, scientific proof of who you are.
Genetics is influencing more and more of our decisions, but we can’t make the right choices if we don’t understand it.
Users may want to know more than what’s in a basic report from a genetic testing company.
Data and privacy issues are tangled up in the DNA reports consumers get from big genetic testing companies – and the third-party sites they turn to in order to glean more from their raw DNA.
It all begins with spitting in a tube like this one.

More people are sending off saliva samples to find out about their genetic roots. But the raw DNA results go way beyond genealogical data – and could deliver unintended consequences.
