Can (and should) a doctor tell my biological relative my genetic results without my consent?

Because genetic changes that cause cause health complications can be hereditary, the information affects not only the person with the mutation but also their biological relatives.

How a scientist says he made a gene-edited baby – and what health worries may ensue

Chinese researcher He Jiankui told a spellbound audience how he created gene-edited babies. With a couple of revealing slides, we can see what he did and speculate what health problems might ensue.

Genetic testing: Should I get tested for Alzheimer’s risk?

Alzheimer's is not only the third leading cause of death in the U.S. but also the most dreaded diagnosis. Genetic testing can help determine susceptibility, but knowing whether to test isn't easy.

Genetic ancestry tests don’t change your identity, but you might

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.

As genetic testing for breast cancer gene mutation expands, questions arise about treatment decisions

A genetics testing company recently won approval from the FDA to market a test that can identify a breast cancer gene mutation. But what are women supposed to do with that information? There's risk involved.

Five things to consider before ordering an online DNA test

Online genetic testing promises many things. Some are the stuff of fantasy, while others, even if scientifically feasible, still carry risks. Consider these five things before ordering a test.
More knowledge about your genetic makeup enables you to make better-informed choices – but at what cost? Shutterstock

Not all genetic tests should be publicly funded – here’s why

It's exciting to think we're on the brink of a genomic revolution in health care. But just because new technology becomes available, it doesn't mean it should automatically be publicly funded.

You’ve got your DNA kit: Now what can you do with it?

The rapid growth of genetic testing and data-gathering could revolutionize health and medicine if governments work to protect people against privacy and societal risks.

Why we should test everyone’s genes to predict disease

If you could take a test that would reveal the diseases you and your family might be more likely to get, would you want to do it?
