How Trillions of Bacteria in Your Body Can Change Your Genes

New research is spurring exciting developments in the microbiome, the trillions of bacteria that make up communities living in our bodies. Scientists are exploring how being aware of imbalances in these bacteria could lead to new diagnoses and treatments. All this could have a positive impact on people’s health.

Why Would Men Need Genetic Testing for Breast Cancer Too?

Men can carry BRCA1/2 mutations too, and they increase a man’s risk for developing prostate cancer, melanoma, pancreatic and testicular cancer — as well as breast cancer (though very rare in men).
It also impacts their daughters’ genetic outlook because fathers pass down the BRCA genetic mutation in the same way as mothers do.

If you know the drug won’t work well for you, do you request more options? These questions aren’t just hypothetical. They’re at the heart of pharmacogenomics. Pharmacogenomics is the study of how your … Read More

3 Ways Genetic Knowledge is Power

“Patients in waiting.” It’s a term we in the world of genetics hear from time to time. The idea is that for certain conditions where there is no cure — or where it may be years before a patient shows symptoms — genetic testing can cause anxiety without providing steps for care. I don’t believe … Read More

A Genetic Test You Don’t Need

As a geneticist and researcher, I believe in the power of genetic testing. By identifying genetic mutations, we can improve care and save lives. But just because we can test something doesn’t always mean we should. Take the MTHFR gene, for example. MTHFR codes for an enzyme that helps your body convert homocysteine into an … Read More
