ist in reis gluten — can a DNA test help?

The question 'is there gluten in rice' is straightforward: rice is naturally gluten-free. A DNA test cannot help diagnose gluten intolerance or celiac disease, which requires blood tests and medical evaluation. The provided context contains no information about gluten or celiac; it discusses other genes (FADS1, APOA2, PPARA, APOE) with small effect sizes and marketing-driven claims. According to the context, these DNA tests are for informational purposes only, not diagnostic, and evidence is rated as 'marketing' or 'unclear'. For gluten-related issues, a doctor should be consulted for proper testing (e.g., anti-tTG IgA, duodenal biopsy). Some DNA tests include HLA-DQ2/DQ8 genotyping, but this is not mentioned in the context and is not sufficient for diagnosis. Therefore, based on the given knowledge, a DNA test does not help answer whether rice contains gluten or whether you have a gluten problem.
