genetic tests

Genetic tests can now tell us a lot about our risk for developing Alzheimer's disease. But that doesn't mean people are prepared to receive the information.

Traditional blood tests still do a better job flagging common inherited diseases. Gene sequencing can be useful for detecting some conditions, but the results can be difficult to interpret.

A variety of genetic tests are available to screen both fetus and parents. One option that's growing in popularity is called an expanded carrier screening. The results can be useful and overwhelming.

There's an explosion of interest in personalized diet approaches and at-home test kits are popping up everywhere. Part of the approach includes analyzing your DNA, but genes can only tell us so much.

A study of whole genome sequencing found that while many people discovered genetic variations linked to rare diseases, they didn't overreact to the news.

A very rare genetic mutation causes some people to develop Alzheimer's in their 30s. It also makes these people the ideal candidates for tests of potential Alzheimer's drugs.

A company has priced its test for mutations linked to breast and ovarian cancer at $249 — far less than the thousands of dollars another firm charges. But is there a downside for the worried well?

Genetic profiling of cancer cells can help guide treatment, but such profiles can be ambiguous. Results would be more accurate if all labs tested normal cells from each patient, too.
