What to watch with HLA-DQ2 and Schlaf?

HLA-DQ2 is a genetic risk factor for celiac disease, but most carriers never develop the condition. Regarding sleep (Schlaf), the link is indirect: undiagnosed celiac disease or non-celiac gluten sensitivity can cause sleep disturbances through inflammation, iron deficiency (restless legs), magnesium or B-vitamin depletion, and gut-brain axis disruption. However, evidence is mostly observational and not strong enough to recommend dietary changes based solely on HLA-DQ2 status. Sleep issues have many causes; a genetic test alone does not diagnose celiac disease. If symptoms like fatigue, bloating, or poor sleep persist, consider serological testing (tTG-IgA) and clinical evaluation. Nutrient status (iron, magnesium, vitamin D, B12) should be assessed via blood tests, not genetics. Evidence: human-moderate.
