This report reads your DNA and sorts every result into one of five plain-language groups, so you can see at a glance what deserves attention and what does not. Nothing here is a diagnosis. A flagged result means your genetics place you above or below the average person for that trait — a reason to ask a question, not a reason to worry.
Sleep — At one point or another, we’ve all tossed and turned in bed, desperately trying to get some much needed rest. Trouble sleeping can lead to chronic tiredness, irritability, difficulty concentrating, and a general lack of energy [R].
These are ordered by how closely they relate to your flagged results — not generic health advice. Marrow does not prescribe, dose, or tell you to take anything. Diet and lifestyle changes are listed first because they are yours to make. Anything you would swallow is listed separately, by name only, as something to raise with a clinician who knows your history and your medications.
Use an airflow device, such as a continuous positive airway pressure (CPAP) machine, every night during sleep.
Schedule and attend sessions in a hyperbaric oxygen therapy chamber as your doctor prescribes, typically for TA about 60 to 90 minutes per session.
Perform airway muscle training exercises daily for at least 30 minutes.
Consider using a body or side pillow to maintain the position throughout the night.
Wear a mandibular advancement device (MAD) during sleep every night.
Visit a licensed acupuncturist for a session, typically lasting between 30 to 60 minutes, once or twice a week.
Aim for 7-9 hours of sleep per night.
Maintain this setup continuously every night during sleep to mitigate symptoms related to GERD or acid reflux.
Finish your last meal of the day at least 3 to 4 hours before you go to sleep.
Practice yoga for at least 20 to 30 minutes a day, most days of the week.
TA the muscles in your feet for 5 seconds, then relax for 30 seconds, and progressively work your way up through the major muscle groups of your body, tensing then relaxing each for 5 and 30 seconds respectively.
Limit red meat to a few times a month and include a moderate amount of dairy products.
These came up in the research behind your flagged results. They are listed by name so you can ask about them. Marrow is not recommending them, and gives no dose. Supplements interact with prescription medication and with each other — that conversation belongs with your clinician.
Of the 15 results in this package, these 3 came back furthest from the population average. Each one below explains what it is, where you sit, and which report it came from. Start here.
Key Takeaways: About 10-40% of differences in people's chances of developing sleep apnea may be due to genetics.
Other important risk factors include being male, older, overweight, nasal congestion issues, a smoker, and drinking alcohol.
Sleep apnea is a disorder that interrupts your breathing while you sleep.
Snoring is a common issue of disrupted breathing during sleep due to restricted airways.
A variety of factors can influence susceptibility to snoring, including your genetics.
While snoring once in a while usually isn’t a serious problem, regular snoring can disrupt your sleep.
Not everything in a genetic report is a warning. These came back protective or better than average.
Daytime sleepiness is the feeling of excessive sleepiness during the day.
People with excessive daytime sleepiness often complain of not feeling well-rested, having difficulty waking up, or accidentally falling asleep during the day, among others [R, R, R].
Daytime sleepiness is usually a consequence of poor sleep duration or quality.
The remaining results, grouped by what they mean. Every one of these is explained in full — with the genes and variants behind it — in the technical version of this report.
Genetics is a predisposition, not a verdict. The single most useful thing you can do with this document is take it to a clinician and talk through the flagged findings — especially any that line up with symptoms you already have or conditions that run in your family. Nothing here changes: your DNA is the same at 60 as it is today, so this report does not expire.
Genotyping was performed on DNA extracted from a buccal (cheek) swab using a genome-wide array. Results are derived from peer-reviewed genome-wide association data and, where applicable, published clinical guidelines. Each report was scored independently against its own reference set. Percentile figures describe where your result sits relative to a reference population.
This is a laboratory-developed test. It has not been cleared or approved by the U.S. Food and Drug Administration. Genotyping does not detect all variants in the genes assessed; the absence of a flagged result does not exclude risk. Predisposition is probabilistic and is modified by environment, lifestyle, ancestry and family history. Results must be interpreted by a qualified healthcare professional and must not be used alone to diagnose, treat, or alter any medication regimen. Marrow does not recommend, prescribe, or dose any supplement or medication.
