If you did @23andMe years ago and haven’t looked since, it’s time to log back in!
Your DNA hasn’t changed, but what we can learn from it has. Genetics research moves fast, and we’re always turning new discoveries into reports you can actually use.
One big example is polygenic risk scores. Instead of looking at one gene at a time, they combine hundreds or thousands of small genetic signals to estimate your risk for conditions like heart disease. Knowing where you stand can help you and your doctor plan ahead.
Go see what’s new in your results. Some of you may need to upgrade to our newer chip to get everything. Learn more at my link in bio.

My favorite meeting of the year is ASHG (@geneticssociety). Being surrounded by scientists and learning is such a privilege, and it was great to visit Montreal to support our @23andMe Research Institute team.
I loved seeing so many people at our booth talking about what becomes possible when millions of participants contribute to research. This is the most fascinating scientific pursuit we could be taking on, and there are so many exciting opportunities ahead as we learn how to predict, prevent and cure disease.
If you’re at #ASHG26, stop by our booth and say hi to the team!

From talking about why the healthcare system can’t fix itself to why research data should be open to everyone, I had a great conversation with @fuelfive on “Progress” by @fiftyyears.
When most people join a research study, they help one group answer one question. At @23andMe, the average participant has contributed to over 230 studies, from Parkinson’s to heart disease to mental health. That only works because people trust us with their data, and they can opt in or out at any time. I believe that kind of choice and transparency is what will bring millions of people into research in an AGI world.
The full episode is out now. Watch at the link in my bio.

Lung cancer rates are rising, particularly in people who are not smokers. When my sister Susan was diagnosed in 2023, we were shocked. When I read the news about Pope Leo XIV, I was again shocked. I hope this is a wake-up call for the world that anyone can get lung cancer, regardless of their history with smoking. More people die of lung cancer than of breast, prostate, and colon cancer combined, and we need a new approach to screening and treatment.
Why is that? Lung cancer often comes with a stigma. The first question everyone asks about my sister is, “did she smoke.” There is almost an assumption that people with lung cancer deserve it.
No one deserves lung cancer. My sister’s foundation, @susanwfoundation, is dedicated to understanding how we can screen, detect and prevent lung cancer.
There is a critical need for broad screening for everyone. Low dose chest CT’s are an effective way of screening for lung cancer and future lung cancer risk. New technologies like Sybil can give a five year risk off a single chest CT. Too few people get a chest CT when they are eligible for screening but there are no guidelines for broad screening for non smokers. We need new screening guidelines and new ways, like blood tests, to screen for lung cancer.
We don’t know why there is a rise in never-smoker lung cancer. There are some genetic associations but they account for a small percentage of cases. @23andMe just published a paper in @sciencemagazine around a genetic variant in EGFR that significantly increases risk of lung cancer. For individuals who have never smoked, carrying the inherited EGFR T790M variant raises the risk of lung cancer by more than 60 times.
23andMe is continuing to study lung cancer with the Lung Cancer Community and I am hopeful we can one day uncover more of the genetic associations. If you or someone you know has lung cancer, please join the community.
We are wishing Pope Leo XIV a smooth recovery. I hope this unfortunate moment can help catalyze the momentum we need to understand the root cause of the rising cases of lung cancer and how we can prevent and treat it.

Today is National Mammography Day. If you have a mammogram coming up, ask: “Is AI being used to read my mammogram?”
About 1 in 5 breast cancers are missed on mammograms the way they’re read today. AI can catch more cancers, estimate your future cancer risk and even spot markers of heart disease risk. I believe this should be standard for everyone, at no extra cost. Until it is, we have to ask for it!
And if breast or other cancers run in your family, talk to your doctor about genetic testing. When you know your risk, you can take steps to prevent cancer or catch it early.
@23andme has a great resource that covers certain types of hereditary cancer risks and genetic testing. Read it at the link in my bio.

Recently, I sat down with @duncancj_ on his podcast, “Artificial Happiness: Fulfillment in the Age of AI,” to talk about rebuilding @23andme as a nonprofit and the work ahead.
Twenty years ago, we started 23andMe to radically empower each person to be in charge of their health. We also set out to overcome the massive conflicts of interest in healthcare by crowdsourcing research and making discoveries that matter to all of us.
Those goals have never changed. As a nonprofit research organization, we’re even more determined to pursue them, and I believe our collective power to do research will transform our understanding of genetics and health.

Thank you to Jeffrey Randall Allen (@legacy.831) and Jennifer Allen (@jwwoo) for coming to the 23andMe office to screen their film, “Life of Lucas,” which chronicles their son Lucas’ experience living with Creatine Transporter Deficiency (CTD). CTD is a rare cerebral creatine deficiency syndrome caused by genetic variants in the SLC6A8 gene, which prevents the body from transporting creatine into the brain and muscles. As of now, the type of CTD Lucas has doesn’t have a cure. Lucas is the reason Jeff competed in (and won 🏆) season one of “Beast Games” hosted by @MrBeast.
It’s always remarkable to me how rare disease parents become the leaders in changing healthcare. Jeff and Jennifer have brought so much awareness to Lucas’s condition and to what families with rare disease go through. They’ve also shown how much more we need to do, and how much more we could do.
Their visit got me thinking about what we can do to make life better for rare disease families. We can’t be part of their day-to-day, but we can help with research, whether that’s building community for people who carry rare disease variants or giving data to researchers. In 2021, our participants helped us find new genetic associations for 33 rare diseases — for some, the first study of its kind ever done.
Stories like Lucas’s are a reminder of why this work matters. If you haven’t yet, I encourage you to watch “Life of Lucas” on YouTube.

Researchers from the @23andMe Research Institute and @DanaFarber identified a rare inherited variant in the EGFR gene, T790M, as the largest known single genetic risk factor for lung cancer. Carriers had 25x higher odds of developing the disease.
Swipe through to learn the science behind the finding and how the variant was traced back to settlers who expanded into Southern Appalachia in the early 1800s.

Why do some people get lung cancer when they have no risk factor? Is it genetic? For some people it just might be.
The @23andMe Research Institute in collaboration with @DanaFarber just published a major study in @sciencemagazine that could have a huge impact in the world of lung cancer research and screening.
The study found that people carrying the rare genetic variant, EGFR T790M, have 25x higher odds of getting lung cancer. Our researchers also traced the ancestry of British and Irish immigrants who carried the rare variant and settled in Southern Appalachia about 200 years ago. Now, that variant is carried by 1 in 2,000 people in parts of the southeastern U.S., compared with 1 in 15,000 nationally.
“One of the remarkable findings here is just how strong an effect a single mutation can have,” said Alexander Gusev, Ph.D., a quantitative geneticist at Dana-Farber. “To my knowledge it’s one of the strongest, if not the strongest, cancer risk increasing mutations that has ever been found.”
These findings are exactly why the 23andMe Research Institute exists. Our large-scale genetic datasets give us and partner researchers the ability to study rare diseases that have been understudied in the past.
These discoveries were made possible thanks to the 3.3 million 23andMe consenting research participants who shared their lung cancer histories for this study. We’re so grateful.
Congratulations to the teams on this work! I look forward to getting this information to people and the opportunity to save lives.

Before @annewoj23 was challenging the healthcare system, she was learning how to challenge it at home.
Her childhood medical record actually came with a warning about her mother, a fierce advocate who questioned doctors, wanted to understand every decision, and taught Anne that you should never be afraid to ask why.
That lesson stayed with her.
Because advocating for your health starts with believing you have the right to understand it.
Hear more about the experiences that shaped Anne’s approach to healthcare and ultimately led her to co-found 23andMe on Breaking Precedent.
Comment EPISODE and we’ll send the full conversation straight to your inbox.
These conversations are stronger because of the partners behind them. Thank you @taskrabbit, @justworks, and @awaysquared for supporting Breaking Precedent and the people willing to question the status quo.
