What to watch with FUT2 and Haut?

The FUT2 variant (fucosyltransferase 2) affects fucosylation of glycoproteins on the gut mucosa, influencing microbiome composition. Some studies suggest links to vitamin B12 absorption and skin barrier function, particularly in inflammatory skin conditions like atopic dermatitis. However, evidence for direct skin recommendations from a DNA test is weak. MyBody-X does not provide specific skin risk scores for FUT2. Practically, ensuring adequate B-vitamin intake and a gut-friendly diet (fiber, fermented foods) may be supportive. Caveat: No clinically validated skin interventions based on FUT2 alone. For skin issues, always consult a dermatologist.
