Gluten Sensitivity
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.
Gluten Sensitivity — Why do some people react strongly to gluten while others can eat it without issue? The answer often lies in our genes, particularly in the HLA gene family. This report examines genetic factors that influence both celiac disease and non-celiac gluten sensitivity, mapping out how different
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.
Check labels for gluten-free certification, and aim to maintain this diet consistently, as even small amounts of gluten can cause symptoms to recur in sensitive individuals.
Identify foods that trigger negative reactions in your body, such as digestive issues, allergies, or headaches, and eliminate them from your diet entirely.
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.
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.
